Antiviral drugs could be �...

Scientists Gain Insight Into How COVID Harms the Heart

New research shows the COVID-19 virus can directly infect coronary arteries, inflaming fatty plaque inside them, which can increase the risk of heart disease and stroke.

This may explain why some people who get COVID-19 have a greater chance of developing heart disease. It also may shed light on why those who already have heart trouble develop more heart-related complications.


Is the First Cure for Advanced Rabies Near?

Rabies virus is incurable and almost always fatal once it has invaded the central nervous system, with the victim doomed to suffer a horrible death.

But researchers now think they’ve found an effective and simple treatment that can cure even advanced cases of rabies.

A monoclonal antibody injected into lab mice successfully protected them from a lethal dose of rabies virus, resear...

RSV Vaccine Given in Pregnancy to Help Shield Newborns Receives Full U.S. Approval

Women may soon have a vaccine they can take during a pregnancy to help protect their newborn from respiratory syncytial virus (RSV).

Following approval one month ago by the U.S. Food and Drug Administration, the Centers for Disease Control and Prevention on Friday also approved the shot, called Abrysvo. That marks the last hurdle needed for the vaccine to become widely available.

However, experts say the public should react to this latest surge not wit...

COVID Virus Is Evolving Three Times Faster in Deer Versus Humans

COVID-19 variants are evolving three times faster in white-tailed deer than in humans, according to a new study.

    European Man May Be 6th Person to Be 'Cured' of HIV

    It's rare for someone with HIV to go into remission and be considered "cured," but a European man may be the sixth to do so.

    First diagnosed with HIV in 1990, the man had been taking antiretroviral drugs since 2005 and received a stem cell transplant two years ago to treat a rare type of blood cancer.

    Known as the “Geneva patient,” the Swiss man in his 50s is one of only six peo...

    Could Your Genes Guard You From the Symptoms of COVID Infection?

    In the world of COVID-19 infections, the majority of patients develop symptoms, while about one-fifth mysteriously don't develop a cough, sore throat or other tell-tale signs of illness.

    COVID Could Harm Men's Sperm Months After Infection

    Having even a mild COVID-19 infection could trigger a months-long drop in sperm, a new study finds.

    Researchers found both lower sperm concentrations and fewer sperm that were able to swim when studying men an average of 100 days after COVID-19 infection, which is enough time for new sperm to be produced.

    “There have been previous studies that show semen quality is affected in th...

    Diabetes Med Metformin Might Help Prevent Long COVID

    A safe, generic diabetes pill can help people avoid long COVID, a new clinical trial shows.

    Metformin cut the risk of long COVID by about 40% for patients who received a two-week course of the drug while battling their infection, the researchers reported.

    The results were even more dramatic if COVID-19 patients began taking metformin soon after infection. Starting on the drug w...

    Your Risk of COVID-Linked Smell Loss Is Much Lower Now: Study

    One of the signature symptoms of COVID-19 infection in the early months of the pandemic was a loss of the sense of smell.

    Now, new research finds that is no longer the case, thanks to the new variants that have been circulating more recently.

    The risk of losing sense of taste or smell is now only about 6% to 7% of what it was during the pandemic's early stages, according to researc...

    1 in 6 Unvaccinated People Struggle With Symptoms 2 Years After Getting COVID

    People unvaccinated for COVID-19 have significant odds of lingering illness if they get the virus, with one in six still suffering symptoms two years later, new research shows.

    Long COVID Can Make It Tougher to Exercise, and Research Is Revealing Why

    Lack of energy for exercise is a common problem for folks with so-called long COVID.

    New research pinpoints the most likely reason why: diminished capacity to get the heart pumping fast enough to support the effort. The name for this is chronotropic incompetence.

    “The amount of aerobic exercise an individual can do is limited largely by the delivery of oxygen by the heart, lu...

    Experts Devise Symptom Checklist to Help Define Long COVID

    Researchers have developed a definition and symptom checklist for long COVID, based on initial findings from a study of nearly 10,000 Americans.

    The study identified a set of 12 long-term symptoms that can occur following infection with COVID-19. These symptoms — ranging from "brain fog" to chest pain — are linked to the effects of the coronavirus on multiple organ systems.


    New Clues to Why Some People Suppress HIV Without Drugs

    Some HIV patients are naturally able to keep the virus fully in check without any medicinal help, a phenomenon that has intrigued scientists for decades.

    New research appears to identify at least one reason why: an abnormally powerful version of an infection-fighting white blood cell called CD8+ T cell.

    CD8+ T cell's are a type of T cell, a normal feature in everyone's immune s...

    Mpox Virus Can Replicate on Surfaces for Days: Study

    Most cases of mpox are spread from skin-to-skin contact, but it is possible to catch the virus by touching a contaminated surface in a house or a hospital room, according to a new study.

    Researchers studying this found temperature made a difference. The virus could survive at room temperature on a surface for up to 11 days. At 4 degrees Celsius (39 degrees Fahrenheit), it could survive f...
