What diseases are coming back?

There are a number of diseases that are seeing a resurgence in recent years, mainly due to a combination of factors such as reduced vaccination rates, increased travel, and overall population growth. One disease that has been on the rise in many parts of the world is measles, which is highly contagious and can be fatal in some cases.

In the United States alone, there were over 1,200 cases of measles reported in 2019, which represents a significant increase from previous years.

Another disease that is making a comeback is polio, which was nearly eradicated in many parts of the world until recently. Although there are now effective vaccines available for polio, there are still many people who are not vaccinated, particularly in developing countries. In 2019, several cases of polio were reported in countries that had previously been considered polio-free, such as the Philippines and Malaysia.

Tuberculosis is also seeing a resurgence in many parts of the world, particularly due to the rise of drug-resistant strains of the disease. This makes it more difficult to treat and control, as the existing antibiotics are becoming less effective. Tuberculosis remains a major public health concern in many parts of Asia and Africa, where it is one of the leading causes of death.

Other diseases that have been on the rise in recent years include pertussis (whooping cough), which can be particularly dangerous for infants, and diphtheria, which is a bacterial infection that can cause severe respiratory problems. Both of these diseases can be prevented with vaccines, but there are still many people who are not vaccinated, either due to lack of access or refusal to vaccinate.

The resurgence of these diseases is a reminder of the importance of vaccines and public health initiatives, as well as the need for continued vigilance in controlling and preventing the spread of infectious diseases.

What is the most recent disease that has been cured?

The most recent disease that has been completely eradicated from the global population is smallpox. This was achieved through a comprehensive vaccination campaign led by the World Health Organization (WHO) that began in the mid-20th century. Over time, this campaign succeeded in completely eliminating smallpox from the face of the planet, making it the first and only disease to have been fully eradicated in human history.

While smallpox has been taken off the list of infectious diseases due to successful eradication, the medical community is still actively in research and development into new treatments and vaccines for numerous diseases that impact the global population. In recent years, promising developments have been made in treatments for diseases like HIV, some forms of cancer, and hepatitis C. These breakthroughs offer hope for the millions of people affected by these diseases around the world.

while we may not know the most recent disease that has been cured, it is important to remember that scientific research is continually evolving and that there is hope for the eradication of more infectious diseases in the future.

When was the last time a cure was found for a disease?

The development of a cure for a disease takes a significant amount of time and resources, with years of research, clinical trials, and scientific testing required. While there have been numerous advancements in the treatment of various diseases, finding a complete cure for a widespread illness remains challenging.

However, recent medical breakthroughs have shown positive results in developing treatments that can significantly improve patients’ quality of life and, in some cases, lead to remission or even a complete cure. For example, in 2019, the U.S Food and Drug Administration approved a new gene therapy treatment for spinal muscular atrophy, which is a rare genetic disorder that affects the muscles and leads to disability and death.

Another example of a recent advancement in disease treatment is the development of immunotherapy for cancer, which involves using the immune system to fight cancer cells. While it is not a complete cure, immunotherapy has shown promising results in cancer treatment, leading to remission and prolonged survival for some patients.

Furthermore, the ongoing COVID-19 pandemic has resulted in unprecedented global efforts to develop treatments and vaccines for the virus, leading to several breakthroughs. For example, the development of mRNA-based vaccines has led to an effective way to prevent the spread of the virus.

While finding a complete cure for a disease remains challenging, ongoing medical research and advancements in science and technology provide hope for better treatment and improved quality of life for patients with various illnesses.

What are the 7 killer diseases?

The 7 killer diseases, also known as the seven major non-communicable diseases (NCDs), are a group of chronic diseases that are responsible for a significant portion of all deaths worldwide. These diseases include cardiovascular diseases (CVDs), cancer, chronic respiratory diseases, diabetes, kidney diseases, liver diseases, and neurological disorders.

Cardiovascular diseases (CVDs) are the leading cause of death globally and include conditions such as heart attacks and stroke. It is estimated that around 17.9 million deaths occur every year due to CVDs, accounting for approximately 31% of all deaths worldwide.

Cancer is the second leading cause of death globally and is responsible for approximately 9.6 million deaths annually. This disease can affect any part of the body and involves the uncontrolled growth of abnormal cells that can invade and destroy adjacent tissue.

Chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), are a significant cause of disability and death worldwide, with an estimated 3 million deaths attributed to this disease per year.

Diabetes is a chronic disease that results in high blood glucose levels and affects more than 420 million people globally. It can lead to serious complications, such as heart disease, kidney failure, and blindness.

Kidney diseases, including chronic kidney disease (CKD), affect millions of people worldwide and can lead to kidney failure, which requires dialysis or a kidney transplant to treat.

Liver diseases, such as cirrhosis, hepatitis B, and hepatitis C, can also be fatal if left untreated. These diseases are on the rise globally due to various factors such as alcohol consumption and viral infections.

Neurological disorders such as Alzheimer’s and Parkinson’s disease, affect millions of people worldwide and can have a significant impact on quality of life.

The 7 killer diseases are a significant health concern globally, and efforts are underway to prevent and manage these chronic conditions. As these diseases are largely preventable, lifestyle changes such as healthy eating, regular exercise, and abstaining from smoking and excessive alcohol consumption can help reduce the risk.

Additionally, early diagnosis and appropriate treatment can improve outcomes for those with these conditions.

Is polio curable now?

Polio is a viral disease that mainly affects children under the age of 5. It has been a devastating illness for centuries, leading to paralysis and, in some cases, death. The great news is that polio is now considered to be curable, thanks to the development of a vaccine.

The polio vaccine was first introduced in the 1950s and has been extremely effective in reducing the number of polio cases worldwide. In fact, according to the World Health Organization, the number of polio cases has decreased by over 99% since the introduction of the vaccine.

The vaccine works by stimulating the immune system to produce antibodies that protect against the poliovirus. It is usually given in two oral doses, spaced a few weeks apart, although some countries have switched to an injectable form of the vaccine.

While the polio vaccine is extremely effective, there are still some challenges when it comes to eradicating the disease completely. Some countries have struggled with vaccine hesitancy, which means that not enough people are getting vaccinated to provide herd immunity. In addition, some areas of the world are difficult to access, which makes it challenging to reach everyone with the vaccine.

Despite these challenges, there is hope that polio will be completely eradicated in the near future. The World Health Organization has set a target date of 2023 for global eradication, and has made significant progress towards this goal. As of 2020, polio is now endemic in just two countries – Afghanistan and Pakistan – down from over 125 countries in the 1980s.

Polio is now considered to be curable thanks to the development of an effective vaccine. While there are still challenges to completely eradicating the disease, progress has been made and there is hope that we will see the end of polio in the near future.

What human disease has been completely eradicated?

One of the few human diseases that have been completely eradicated is smallpox. This disease was notoriously deadly and highly contagious, with a mortality rate of up to 30 percent in those infected. The eradication of smallpox is an incredible achievement for humanity, which required the efforts of various international health organizations, including the World Health Organization (WHO).

The eradication program began in 1958 and involved a massive global vaccination campaign, which targeted millions of people living in affected countries.

The main vaccine used to fight smallpox was the live-virus vaccine, which was highly effective at preventing the disease. The vaccine was administered through a small puncture in the skin, usually on the upper arm, and produced an immunity that lasted for years. The vaccine’s success was largely due to the efforts of public health officials who worked tirelessly to deliver the vaccine to remote and hard-to-reach areas, often facing numerous obstacles and challenges along the way.

The last case of smallpox was recorded in Somalia in 1977, after which the WHO declared the disease eradicated. The eradication of smallpox is considered one of the most significant public health achievements of the twentieth century, as it has saved millions of lives and prevented countless others from suffering its devastating effects.

It also serves as an inspiration for future health initiatives, highlighting what can be achieved when the global community works together towards a common goal.

Is TB making a comeback?

Tuberculosis (TB) is a bacterial infection that primarily affects the lungs, but can also spread to other parts of the body such as the brain and spine. TB has been a significant public health problem for centuries, causing millions of deaths around the world. With the development of drugs and vaccines, the number of cases of TB has decreased significantly over the years.

However, recent evidence suggests that TB may be making a comeback in some parts of the world.

There are several reasons for this resurgence of TB. One of the most significant factors is the emergence of drug-resistant strains of Mycobacterium tuberculosis, the bacterium that causes TB. These strains are resistant to one or more of the drugs commonly used to treat TB, making it much more difficult to cure the infection.

In addition, many of these strains are also highly infectious, allowing them to spread easily from person to person.

Another factor contributing to the comeback of TB is the growing number of people with weakened immune systems. People with HIV/AIDS or other conditions that affect the immune system are much more susceptible to TB infection, and are at a higher risk of developing active TB disease once they are infected.

As the number of people living with these conditions increases around the world, so does the number of cases of TB.

Finally, the rise of global travel and migration has also played a role in the resurgence of TB. Travelers from areas with high TB prevalence can unknowingly bring the disease with them to other parts of the world, where it can spread quickly through local populations.

So, in conclusion, TB may be making a comeback due to a combination of factors, including the emergence of drug-resistant strains, the increasing number of people with weakened immune systems, and the rise of global travel and migration. It is essential that public health officials and medical professionals remain vigilant in monitoring and controlling the spread of TB to ensure that we continue to make progress in the fight against this deadly disease.

Why has there been a resurgence of TB?

There are several factors contributing to the resurgence of tuberculosis (TB) in recent years. One of the primary reasons is the emergence of drug-resistant strains, which are incredibly difficult to treat and can spread rapidly. The development of drug resistance is primarily caused by inadequate treatment of TB, often due to factors such as insufficient resources and poor adherence to treatment protocols.

Another key factor in the resurgence of TB is the increasing spread of the disease in vulnerable populations, such as people living with HIV/AIDS and those living in crowded, unsanitary conditions. Poverty, malnutrition, and other socioeconomic factors also increase the susceptibility of individuals to TB infection.

Additionally, the global movement of people through travel and migration has enabled TB to spread more quickly across borders, as well as presenting new challenges to TB control efforts. This is especially true in low-income countries with weaker health care systems, where cases of TB often go undetected, untreated, or under-treated.

To combat the resurgence of TB, efforts need to focus on improving access to treatment, strengthening public health systems, and investing in the development and dissemination of effective TB vaccines. Additionally, addressing the underlying social determinants of TB infection, such as poverty and poor living conditions, is essential for reducing the prevalence of the disease.

a multi-faceted approach is required to tackle the complex factors contributing to the resurgence of TB, and increased global cooperation and resources are needed in this effort.

What is the future outlook for tuberculosis?

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and has been a major public health problem for decades. Although progress has been made in reducing the global burden of TB in recent years, it remains a significant cause of morbidity and mortality worldwide. The future outlook for tuberculosis is influenced by various factors, including advances in diagnostics and treatment, continued investment in research and development, and socioeconomic determinants.

One possible future for tuberculosis could be the development of improved diagnostic tools, such as rapid point-of-care tests, that can accurately diagnose TB and drug-resistant TB quickly and efficiently. Advanced imaging techniques such as computerized tomography and magnetic resonance imaging may also help in the early diagnosis of TB and better management of TB-associated complications.

The development of new drugs and vaccines is also crucial to control TB in the future. There are currently several new treatment regimens in clinical trials, and drugs such as bedaquiline, which were previously only available under compassionate use, are now approved for use. Vaccines, such as the M72/AS01E vaccine, which targets both latent and active TB, are in advanced clinical trials, and show promise in improving TB control.

However, despite these advances, tuberculosis has become more difficult to treat in recent years due to the emergence of drug-resistant TB. Multi-drug resistant TB (MDR-TB) and extensively-drug resistant TB (XDR-TB) pose a serious threat to global TB control efforts, and the World Health Organization (WHO) has set a target of achieving a 50% reduction in TB incidence rate between 2015-2030.

To achieve this target and control drug-resistant TB, a combination of active case-finding, appropriate treatment regimens, effective infection prevention and control measures, and enhanced research and development efforts is required.

Another key factor that will impact the future of TB control is the role of social determinants of TB. TB disproportionately affects individuals and communities living in poverty, migrants, and those with co-morbidities such as HIV, malnutrition, and diabetes. Addressing the social determinants of TB such as poverty, poor living conditions, and inadequate healthcare systems will require cross-sectoral collaboration and political commitment.

The future outlook for tuberculosis is a complex and multifaceted issue. Advances in diagnostics and treatment tools, development of new drugs and vaccines and addressing the social determinants of TB will all play a significant role in controlling the global TB burden in the years to come. It will require a collective effort from governments, healthcare providers, researchers, and communities to reach the WHO targets and achieve a TB-free world.

Is TB a thing anymore?

Tuberculosis (TB) is still a significant global health concern, albeit the prevalence of the disease has decreased in recent years. TB is an infectious disease caused by the bacteria Mycobacterium tuberculosis. It typically affects the lungs, but it can also affect other parts of the body, such as the joints, spine, and kidneys.

TB has been around for thousands of years, and it remains a leading cause of death from a single infectious agent worldwide. According to the World Health Organization (WHO), in 2019, there were an estimated 10 million cases of TB globally, and 1.4 million people died from the disease. While these numbers are concerning, there has been a gradual decline in the number of people affected by TB over the past few decades, thanks to increased awareness, diagnosis, and treatment efforts.

TB is a highly infectious disease that spreads through the air when an infected person coughs or sneezes. People at the highest risk of TB infection are those who live in overcrowded or poorly ventilated areas and those with weakened immune systems such as people living with HIV/AIDS.

The symptoms of TB include coughing, fever, night sweats, weight loss, and fatigue. While TB can be treated with antibiotics, the treatment can be lengthy and complicated, involving multiple medications taken over several months. Incomplete treatment is a significant cause of the emergence of resistant strains of TB.

Tb is still very much a thing, and it remains a significant global public health challenge. Nevertheless, significant progress has been made in the diagnosis, prevention, and treatment of TB, and ongoing efforts are being made to eradicate the disease entirely. It is crucial to continue raising awareness about TB, ensuring that people living with TB have access to diagnosis and treatment, and preventing the spread of the disease.

Why did they stop vaccinating for TB?

Bacillus Calmette-Guérin (BCG) vaccine was developed in the early 1900s as a vaccine against tuberculosis (TB). It was named after its developers, a Frenchman Albert Calmette, and a Guinean veterinarian Camille Guérin. The vaccine was first used in humans in 1921 and was widely used in Europe in the following decades.

However, the use of the BCG vaccine for TB control has been controversial and has undergone several changes over time. In some countries, BCG vaccination is given routinely to newborns, whereas in others, it is given selectively to high-risk groups.

One of the main reasons why BCG vaccination has been stopped in some countries is its variable efficacy against pulmonary tuberculosis, which is the most common and transmissible form of TB. Several studies have shown that BCG is highly effective against severe forms of tuberculosis, such as TB meningitis and disseminated TB in children, but its protection against pulmonary TB in adults is variable and generally lower.

This is due to several factors, including variations in the vaccine strain and host factors.

Another reason why some countries stopped BCG vaccination is the low prevalence of TB in their population. Although TB is still a major global health problem, with about 10 million new cases and 1.5 million deaths each year, the disease is highly concentrated in certain regions, such as Africa and Asia.

In some countries, such as Australia and the United States, the incidence of TB is very low, and vaccination may not be cost-effective or necessary.

In addition, BCG vaccination has been associated with certain adverse events, such as injection site reactions, regional lymphadenopathy, and disseminated BCG infection in immunocompromised individuals. Although these adverse events are rare, they have raised concerns about the safety and feasibility of BCG vaccination.

Finally, the availability of more effective and safer vaccines against TB has also contributed to the discontinuation of BCG vaccination in some countries. Several new TB vaccines are currently under development, such as the M72/AS01E vaccine, which has shown promising results in clinical trials. These vaccines are expected to provide better and more long-lasting protection against TB and may replace BCG in the future.

The decision to stop vaccinating for TB depends on several factors, including the efficacy and safety of the vaccine, the prevalence of TB in the population, and the availability of alternative vaccines. Although BCG vaccination has been highly effective in some settings, its variable efficacy against pulmonary TB and its potential adverse events have led some countries to discontinue its use.

However, BCG remains an essential vaccine for TB control in many countries, especially in low- and middle-income countries with a high burden of TB.

Can you still get TB after being vaccinated?

Yes, it is possible to get tuberculosis (TB) after being vaccinated. The BCG vaccine, which is the most common vaccine used to prevent TB, has been found to be effective in preventing severe forms of TB in children. However, it does not confer complete protection against TB infection in adults. Additionally, the vaccine may not be effective in preventing all strains of the TB bacterium.

The BCG vaccine works by stimulating the immune system to produce a response against the bacterium that causes TB. However, the response generated by the vaccine can vary widely from person to person, and may not be strong enough to completely prevent infection in some individuals. Moreover, the effectiveness of the vaccine can also be influenced by factors such as the age at which it is administered, the dose used, and the strain of the bacterium causing the TB infection.

Furthermore, the vaccine does not provide any protection against other types of mycobacteria that can cause TB-like symptoms. In some cases, a person who has been vaccinated with the BCG vaccine may still become infected with other mycobacteria, which can lead to a TB-like disease.

It is also worth noting that the BCG vaccine may cause false positive reactions on tests for TB infection, which can lead to unnecessary treatment and other complications. This is because the vaccine can cause a mild TB-like reaction in some individuals, which can be mistaken for a true TB infection.

While the BCG vaccine can be effective in preventing severe forms of TB in children, it does not provide complete protection against TB infection in all cases, and may not be effective against all strains of the TB bacterium. It is therefore important for individuals who have received the vaccine to continue taking precautions to avoid TB infection, such as avoiding close contact with people who have active TB disease, and seeking prompt medical attention if they develop symptoms of a TB infection.

What has led to the resurgence of tuberculosis in the 1990’s?

There are several factors that have led to the resurgence of tuberculosis in the 1990s. One of the major reasons is the emergence of HIV/AIDS epidemic. People infected with HIV have weaker immune systems, which makes them more susceptible to tuberculosis infection. HIV weakens the immune system by attacking the T cells or CD4 cells, which are responsible for fighting off infections.

When the T cells are damaged, the body is less able to fight off infections like tuberculosis. Globally, it has been estimated that around 40% of people living with HIV are co-infected with tuberculosis.

Another factor that contributed to the resurgence of tuberculosis in the 1990s is the increasing number of people living in poverty. Poverty is associated with poor living conditions, overcrowding, poor nutrition, and limited access to healthcare. These conditions make people more vulnerable to tuberculosis infection and more prone to developing severe forms of the disease.

In addition, poverty often leads to poor adherence to tuberculosis treatment, which increases the risk of drug-resistant tuberculosis. It is estimated that around 80% of the world’s tuberculosis cases are concentrated in low and middle-income countries.

The emergence of drug-resistant tuberculosis is another major factor that contributed to the resurgence of tuberculosis in the 1990s. Drug-resistant tuberculosis occurs when the bacteria that cause tuberculosis become resistant to the drugs used to treat the disease. This can happen when people do not complete their full course of tuberculosis medication, or when they are not given the correct drugs or dosage.

The emergence of drug-resistant tuberculosis has made it more difficult to control the disease and has led to an increase in deaths.

Social factors such as migration and urbanization have also contributed to the resurgence of tuberculosis in the 1990s. People who move to urban areas or across borders are often exposed to new strains of tuberculosis, making them more vulnerable to infection. Urbanization also leads to overcrowding, which increases the risk of tuberculosis transmission.

In addition, urban slums often lack basic amenities like clean water, which increases the risk of tuberculosis infection.

The resurgence of tuberculosis in the 1990s can be attributed to several factors, including the emergence of HIV/AIDS epidemic, increasing poverty, drug-resistant tuberculosis, migration, and urbanization. To effectively control tuberculosis, it is important to address the underlying social determinants of the disease, such as poverty, poor living conditions, and limited access to healthcare.

Treatment of HIV/AIDS is also important for preventing tuberculosis and reducing the burden of tuberculosis in people living with HIV. Furthermore, it is crucial to improve tuberculosis diagnosis and treatment programs and to introduce new vaccines and drugs to combat tuberculosis.

Is TB becoming more common?

Tuberculosis (TB) is an infectious disease that has affected humans for centuries. Despite significant advancements in medicine and public health practices, TB continues to be a global health threat. According to recent statistics from the World Health Organization (WHO), TB is one of the top 10 causes of death worldwide, affecting approximately 10 million people annually.

The incidence of TB varies widely by region, with the majority of new TB cases occurring in low- and middle-income countries. Factors such as poverty, malnutrition, crowded living conditions, and limited access to healthcare contribute to the high rates of TB in these areas. In addition, the emergence of drug-resistant strains of TB has further complicated efforts to control the disease.

it is difficult to make generalizations about whether TB is becoming more common, as trends vary by country and region. Some areas have seen a decrease in TB rates over time, while others continue to struggle with high rates of the disease. In general, efforts to control TB involve a combination of prevention, early detection, and effective treatment.

This includes measures such as vaccination, targeted screening for high-risk populations, and access to quality healthcare services. Additionally, public health education and awareness campaigns can play an important role in reducing stigma and promoting adherence to treatment protocols.

While the incidence of TB may fluctuate over time and across regions, it remains an urgent global health challenge. Addressing this issue will require sustained investment in public health infrastructure, research, and community-level interventions.

Is active TB increasing in the US?

According to the Centers for Disease Control and Prevention (CDC), the number of active cases of tuberculosis (TB) in the United States has been declining overall. However, there are still certain populations that are at higher risk for the disease, such as people born in countries with high TB rates, people who have spent time in correctional facilities or homeless shelters, and people who inject drugs.

In 2019, there were a total of 8,920 reported cases of TB in the US, which represents a 1.1% decrease from the previous year. However, the decline in TB cases has slowed in recent years, and there has been a small increase in the number of cases among non-US born individuals.

One reason for the decline in TB cases overall is the widespread use of antibiotics to treat the disease. However, the emergence of drug-resistant strains of TB is a growing concern, as these strains are more difficult to treat and may require longer, more expensive treatment regimens.

To continue the decline in TB cases, it is important to identify and treat cases early, as well as to provide preventive treatment to those at high risk for the disease. The CDC recommends targeted testing and treatment for people at increased risk for TB, as well as continued efforts to detect and treat cases in the wider population.

Additionally, efforts to address the social determinants of health, such as poverty and access to healthcare, can help reduce the incidence of TB in the US.
