Sexually transmitted infections (STIs) are a global public health challenge. This can lead to many health risks, including serious reproductive, physical, and mental health issues. Furthermore, STIs can also amplify the risk of transmitting HIV. As per a 2019 study by Rowley et al., the rates at which people have contacted STIs are increasing globally, with more than 1 million STIs daily.
New data however indicates that the spread of STI may be slowing down, as the rate of total cases for three major infections fell by 2% in 2023 as compared to the previous year, reveals the Centers for Disease Control and Prevention (CDC).
As per the data, more than 2.4 million people were diagnosed with syphilis, gonorrhoea, and chlamydia last year, which marked a 2% decrease from 2022 and a 4% drop from the year 2019. The data also reveals 10 states in the US with the most number of STIs, despite the drop in the overall cases. The top 10 states, starting with the state on number 10th are:
9. Arkansas: 869.5 cases per 100,000 people
8. South Carolina: 882.8 cases per 100,000 people
7. North Carolina: 911.5 cases per 100,000 people
6. Alabama: 952.3 cases per 100,000 people
5. Georgia: 996.5 cases per 100,000 people
4. South Dakota: 1,013.9 cases per 100,000 people
3. Alaska: 1,063.4 cases per 100,000 people
2. Mississippi: 1,067.7 cases per 100,000 people1. Louisiana: 1,181.5 cases per 100,000 people
As per a 2021 study, published in the book Sexually Transmitted Infections: Adopting a Sexual Health Paradigm, also published in the online portal of the National Center for Biotechnology Information, 2.6 million infections were found to be prevalent in the United States in 2018. 6.9 million infections common to people between the ages of 15 and 59. Another 2021 study states that women are 6 times more likely than men to have a prevalent infection.
The most common STIs as per CDC data are syphilis, chlamydia and gonorrhoea. The latest data shows that the cases were recorded at 734 per 100,000 people.
More than 209,000 cases of syphilis were reported in the US in 2023. While this was the highest number reported since 1950, it was just 1% increase from 2022, with an overall decrease in the total cases of STIs being reported.
As per the World Health Organization (WHO), this is a preventable and curable bacterial STI. However, many people do not get to know about it as it does not have any symptoms. It can be transmitted during oral, vaginal, and anal sex, in pregnancy and through blood transfusion.
Round, painless and hard sore near genitals, anus
Non-itchy rashes on palms and feet
White or grey lesions in moist areas could be anus or labia
Between 2022 and 2023, the cases of chlamydia were steady and decreased by less than 1%. It is one of the most common STIs caused by Chlamydia trachomatis. It does not cause any symptoms, which is why people would not know if they have it. However, it is curable. You can have chlamydia if you have unprotected sex, or can be passed down in pregnancy.
The cases of gonorrhoea also fell in 2023 and dropped by 8%. It is also one of the most common STIs, with 1 in 10 men being infected and 5 in 10 women infected by the same. It is caused by Neisseria gonorrhoeae by vaginal intercourse, oral sex, and anal sex, and can be passed to a child in pregnancy. However, it is curable.
Unusual vaginal discharge in women
Unusual discharge in men from the tip of the penis
Pain or burning sensation while passing the urine
Inflammation of the foreskin in men
Bleeding between periods, heavier periods and bleeding after sex in women
Shingles, a painful viral infection due to the reactivation of the varicella-zoster virus (VZV), is primarily known for its blistering rash and nerve pain. New research indicates, however, that shingles vaccine can be significant in preventing dementia. This recent finding paves the way to new avenues to understand the association between viral illness and brain wellness, which might change preventive treatment against cognitive degeneration in aging individuals.
Once a person has had chickenpox, he or she carries the varicella-zoster virus for life. The virus lies dormant within nerve cells and may reappear years later as shingles, commonly because of compromised immunity with age, stress, or illness.
Shingles appears as a painful rash, typically on one side of the body, and may persist for weeks. Aside from the rash, the infection may cause severe complications like postherpetic neuralgia (PHN), a long-term nerve pain syndrome that lasts for months or even years. In rare instances, shingles may infect the eye, causing blindness.
The Centers for Disease Control and Prevention (CDC) estimates that approximately 1 in every 3 Americans will develop shingles at some time during their lifetime. Vaccines have been recommended to avoid the condition, but recent studies indicate they might also have an added bonus—prevention from dementia.
Dementia, such as Alzheimer's disease, is a rapidly increasing worldwide health issue, with millions of older adults at risk. Although the causes of dementia are still unknown, researchers have long suspected that some viruses, specifically those in the herpes family (which includes VZV), may play a role in cognitive decline.
A study recently published in Nature determined that getting the shingles shot lowered the risk of developing dementia dramatically. Scientists followed more than 280,000 elderly people in Wales who got the original shingles vaccine, Zostavax, and identified a 20% decrease in dementia incidence over the next seven years.
Lead author Dr. Pascal Geldsetzer of Stanford University said the results were "very robust" and added that women appeared to gain more benefit from the vaccine than men. Since women are at greater risk for dementia, these results could have important implications for future prevention efforts.
Although no one knows the exact mechanisms, several theories discuss how the shingles virus might enhance the risk of dementia:
Inflammation and Brain Damage: The varicella-zoster virus has the ability to cause inflammation in the body, including the brain. Chronic inflammation is recognized to speed up cognitive decline and may play a role in neurodegenerative diseases such as Alzheimer's.
Vascular Effects: The virus has the ability to infect blood vessels in the brain, leading to clots or constricting blood flow. Decreased cerebral circulation is a well-documented risk factor for dementia and stroke.
Amyloid Protein Formation: A study by the University of Colorado Anschutz Medical Campus indicates that shingles can encourage the formation of amyloid plaques, a characteristic of Alzheimer's disease. These adhesive proteins clump together in the brain, interfering with normal function and speeding up cognitive decline.
The research suggests that shingles vaccination can lower the risk of dementia by inhibiting reactivation of the virus and triggering inflammation in the brain. It is unclear, however, whether the same protective mechanism works for the newer, more effective Shingrix vaccine, which supplanted Zostavax in 2020.
In contrast to Zostavax, which had a live but attenuated form of the virus, Shingrix is a genetically modified vaccine that consists of certain viral proteins to stimulate an immune response. Shingrix has been 97% effective in preventing shingles in clinical trials, versus 51% for Zostavax. Whether it can help prevent dementia, however, is an open question scientists are eager to investigate.
The CDC advises Shingrix for people aged 50 and above, as well as younger adults with compromised immune systems. The vaccine is given in two doses, spaced a few months apart, and is very effective in preventing shingles and its complications.
With these advantages, however, vaccine acceptance continues to be low, with less than 40% of eligible Americans having gotten their shots. The most frequent side effects are mild flu-like symptoms and pain at the site of injection, but experts point out that the advantages far outweigh the risks.
Although shingles vaccination holds great potential for dementia prevention, it is not the only answer. Experts suggest an integrated approach to brain health that involves:
Living an Active Lifestyle: Physical exercise on a regular basis enhances circulation to the brain and averts cognitive loss.
Healthy Nutrition: A diet modelled on Mediterranean cuisine, featuring high intakes of fruits, vegetables, whole grains, and healthy fats, is supportive of brain function.
Social and Mental Stimulation: Mental activity with reading, puzzles, or social engagement may build cognitive reserve.
Control of Chronic Illnesses: Control of high blood pressure, diabetes, and cholesterol lowers the risk of dementia.
The association of shingles with dementia risk demonstrates the complex ways infectious illnesses affect overall well-being. Finding that shingles vaccination can decrease risk of dementia adds yet another persuasive argument to convince older people to be vaccinated. Although more study is necessary to validate the results, the study holds out hope that a straightforward vaccine has a key part to play in maintaining cognitive capacity and enhancing the quality of life among aging groups.
As scientists continue to investigate the link between viral infections and brain health, one thing is certain: guarding yourself against shingles might have advantages that reach far beyond the skin. With the increasing global burden of dementia, interventions such as vaccination could become a key part of the arsenal in the battle against cognitive decline.

Dr. Jayanta "Jay" Bhattacharya, has officially assumed office as the 18th Director of the National Institutes of Health (NIH), bringing a new era of leadership to the country's leading medical research agency. His confirmation, approved by the U.S. Senate on March 25, 2025, represents a major change in NIH's direction, in line with President Trump's Make America Healthy Again Commission.
Dr. Bhattacharya comes on board amid widespread federal health system reorganization. HHS Secretary Robert F. Kennedy Jr. just announced a comprehensive overhaul that involves firing about 1,200 NIH staff. In an all-staff letter, Dr. Bhattacharya accepted the challenges to come, promising staff that he will make changes with compassion and openness.
"I am aware that I am coming into NIH during a period of unprecedented change. Every corner of the federal government is being scrutinized — and NIH is no exception," he wrote. Grateful for the efforts of the affected employees, he went on to say, "Many of our good colleagues are losing their jobs, and that in no way reflects the quality of their effort.". I wish to thank most sincerely those who will be impacted for all that you have done for the mission of the NIH."
A leading Stanford health economist and physician, Dr. Bhattacharya has been a long-time advocate for scientific integrity and academic freedom. His mission is to reaffirm public faith in biomedical studies, with priority placed on maintaining integrity, being reproducible, and being innovative in NIH-sponsored research.
Most importantly, our findings will only be impactful if the public is confident in our results and believes that we are working on their behalf," said Dr. Bhattacharya. NIH will, under his leadership, focus research on solving directly the nation's most critical health priorities, especially chronic conditions like cancer, diabetes, heart disease, and obesity.
NIH has experienced deep budgetary shifts over the last few months, with grant support suspended and restored, and indirect university research costs capped prior to the intervention of a federal judge. Dr. Bhattacharya is anticipated to negotiate these budget intricacies in order to secure ongoing support for innovative scientific discoveries.
Secretary Kennedy voiced his confidence in the new director, stating, “Under Dr. Bhattacharya’s leadership, NIH will restore its commitment to gold-standard science. I’m excited to work with him to ensure NIH research aligns with our Administration’s priorities — especially tackling the chronic disease epidemic and helping to Make America Healthy Again.”
Dr. Bhattacharya has been vocal about the importance of free speech in scientific discourse. In October 2024, he tweeted on X (formerly Twitter), "If you support government regulation of disinformation, you are an enemy of free speech." Now, as NIH Director, he has directed agency personnel to prepare a list of grants and contracts focused on fighting misinformation and disinformation, a step that could be evidence of a change in how government agencies handle scientific controversy and public messaging.
Prior to coming to NIH, Dr. Bhattacharya was a tenured professor at Stanford University, where he worked on population aging and chronic diseases, especially among vulnerable populations. He co-authored the Great Barrington Declaration in the COVID-19 pandemic, calling for a focused protection strategy instead of broad lockdowns.
As he enters this critical position, Dr. Bhattacharya is charged with guiding NIH through trying times, keeping research priorities in synch with public health needs, and reaffirming the agency's commitment to scientific integrity. His tenure will begin a new era for NIH, one that holds the promise of reforms to promote innovation, accountability, and reinvigorated faith in medical research.

Val Kilmer, the legendary actor, passed away at 65 after enduring years of health struggles. Diagnosed with throat cancer in 2015, he underwent a tracheotomy that cost him his voice. Though he initially kept his illness private, Kilmer later chose to share his journey, raising awareness about the disease.
Hollywood mourns the loss of Val Kilmer, the beloved actor known for his popular roles in Top Gun, Batman Forever, and The Doors. The 65-year-old star passed away in Los Angeles on Tuesday, as confirmed by his daughter, Mercedes Kilmer. The cause of death was pneumonia, a deadly lung infection which remains one of the leading causes of death worldwide.
Kilmer died after having spent a decade struggling with complications related to health. Diagnosed with throat cancer in 2014, he endured multiple treatments, including chemotherapy, radiation, and a tracheotomy. Though he successfully fought cancer, the medical procedures left him with lasting health challenges, including the inability to speak naturally. His battle with illness was documented in the 2021 film Val and in his 2020 memoir 'I’m Your Huckleberry', where he opened up about his struggles for the first time.
Although his fans thought he had recovered, his previous health conditions might have predisposed him to the infections that came as a result of respiratory problems, including pneumonia, which ultimately caused his death.
Pneumonia is a type of infection that will cause inflammation to the air spaces in one, or both lungs, filling it with pus, or fluid and causing breathing issues. Pneumonia can result from bacteria, viruses, and fungi and most especially poses great danger to someone with a low immune system, or an individual with preconditions.
For elderly people and those with pre-existing health issues, pneumonia can become life-threatening very rapidly, as happened to Val Kilmer. Pneumonia is still a leading cause of hospitalization and death, despite advances in medicine, particularly among people with a history of cancer, respiratory conditions, or weakened immune systems.
Throat cancer and its therapies may have a lasting effect on breathing health. Kilmer's struggle with throat cancer resulted in large-scale medical interventions, such as a tracheotomy, that changed his voice and breathing to be less normal. This medical procedure, in which an incision is made in the neck to assist the air in entering the lungs, may predispose people to getting respiratory infections, such as pneumonia.
Additionally, chemotherapy and radiation therapy, which are often used to treat cancer, can impair the immune system. This makes patients more susceptible to infection, including infections that attack the lungs. The long-term use of feeding tubes, swallowing problems due to cancer of the throat, and aspiration of food or liquids into the lungs can also contribute to the risk of pneumonia.
Kilmer's situation highlights the long-term dangers that confront cancer survivors even after they have been declared cancer-free. Although his cancer was remission, the long-term consequences of his treatment were most likely responsible for his vulnerability to pneumonia, underscoring the need for ongoing monitoring and respiratory therapy in cancer survivors.
Pneumonia is usually underappreciated but can quickly develop into a deadly disease, particularly for those with compromised immune systems. This is how pneumonia becomes lethal:
Severe pneumonia may result in respiratory failure, with the lungs failing to supply the body with sufficient oxygen or clear carbon dioxide. It can result in hypoxia (oxygen deficiency), damaging essential organs such as the brain and heart.
Pneumonia has the potential to cause sepsis, a potentially fatal response to infection in which the body's immune system attacks its own tissues. Sepsis can result in organ failure, such as kidney failure, heart failure, and permanent lung damage, which leads to death if left untreated.
Cancer survivors and patients, such as Kilmer, are at increased risk of suffering from serious complications of pneumonia. Their immune systems have been weakened by previous treatments, which makes it more difficult for their bodies to combat infections. Moreover, structural damage to the lungs from previous radiation or surgery can also hinder their recovery.
On occasion, pneumonia results in fluid buildup around the lungs (pleural effusion), further complicating breathing. If the infection becomes systemic, it can cause respiratory failure and multi-organ failure.
Val Kilmer's death reminds us of the quiet risks of pneumonia, especially for those with a background of serious disease. His journey—from battling throat cancer to overcoming the odds and returning to the screen—was an inspiration to many.
