Animal Study Offers Hope for a Better Herpes Treatment

Aiming to deliver a one-two punch to the herpes virus, animal research on an experimental drug found it tackled active infections and reduced or eliminated the risk of future outbreaks.

Existing treatments, such as Zovirax, Valtrex or Famvir, are only effective at the first task; they can help treat cold sores and genital eruptions once a herpes outbreak occurs. But...

Living With HIV Raises Odds for Sudden Cardiac Death

People living with HIV have to take powerful drug cocktails to keep their disease in check, but a new study finds they also need to worry about a doubled risk of sudden cardiac death.

Unlike a heart attack caused by a blocked heart artery, sudden cardiac death can happen without warning and is triggered by an electrical malfunction that causes an irregular heartbeat. Within minutes, there...

Less Than 1% of People Who've Had Severe COVID Get Re-Infected

People who have had severe COVID-19 and worry about going through another bout of it can relax: New research finds that less than 1% of people who've had a severe coronavirus infection get re-infected.

Compared to adults, the babies produced relative...

Will People Really Need a Yearly COVID Booster Vaccine?

As the number of people fully immunized against COVID-19 rises into the hundreds of millions, immunologists and infectious disease experts now are pondering a new question in the unfolding pandemic.

Namely, how long will vaccine immunity last, and will people who've gotten the jab need booster shots to maintain their protection?

It's an important question, as waning immunity in the ...

Colds, Bronchitis Cases Resurged After Texas Eased COVID Rules

After Texas relaxed COVID-19 restrictions, other respiratory illnesses -- such as colds, bronchitis and pneumonia -- made rapid rebounds.

Pathologists from Houston Methodist Hospital found that the rhinovirus and enterovirus infections that can trigger these illnesses started rebounding in the fall of last year after Texas eased capacity limits in bars and restaurants.

Are Some Foods Super Bitter to You? You Might Have Lower COVID Risk

If you can't stand broccoli, celery or kale, you may be a supertaster, and it just might protect you from COVID-19.

Supertasters are folks who are highly sensitive to bitterness. They're not only less likely to get COVID-19 than people who aren't so sensitive to sharp, pungent flavors, they're also less likely to wind up hospitalized with it, the researchers said.

What's more, super...

In 10 Years, COVID-19 Could Be 'Just the Sniffles'

The virus fueling the COVID-19 pandemic could become just an ordinary sniffle-causing nuisance within the next 10 years, a new study suggests.

Researchers stressed that the projection is based on mathematical models, and not a crystal-ball prediction.

But, they say, given what's known about the human immune response to SARS-CoV-2 -- the virus that causes COVID-19 -- it is possible t...

'Brain Fog' Can Linger With Long-Haul COVID

MONDAY, May 24, 2021 (HealthDay News) - As researchers work to learn more about COVID-19 and so-called long-haulers, a new study suggests "brain fog" can persist and even worsen for those who were infected months before.

Long-haulers continue to have symptoms long after their COVID diagnosis, and these symptoms can be mental as well as physical.

"People have trouble problem-solving,...

In Newly Discovered Case, a Coronavirus Has Jumped From Dog to Human

A new coronavirus that appears to have jumped from a dog to a child has been discovered from a case three years ago, but it's unclear what threat it may pose.

Many Kids Who Develop Severe COVID-Linked Syndrome Have Neurologic Symptoms

In very rare cases, children infected with the new coronavirus can develop a severe illness known as multisystem inflammatory syndrome (MIS-C). Now, research finds that these young patients often develop neurologic symptoms along with the respiratory issues they might face.

These neurologic symptoms were present in half of children who were hospitalized with MIS-C, U.K. researchers say.

U.K. Variant Won't Trigger More Severe COVID, Studies Find

Two new studies out of Britain find that although the now-dominant "U.K. variant" of the new coronavirus does spread more quickly, it does not appear to lead to more severe disease in those made ill.

The findings should help allay fears that more patients will die after infection with the variant, officially labeled B.1.1.7.

Scientists published the findings online April 12 in two

Bright Side: Sunnier Areas Have Lower COVID-19 Death Rates

COVID-19 might have a tough new foe: The sun.

New research shows that sunnier regions of the United States have lower COVID-19 death rates than cloudier areas, suggesting that the sun's UV rays might somehow provide some protection against the disease.

The effect is not due to better uptake of the healthy "sunshine vitamin," vitamin D, noted the Scottish research team led by Richard...

Two Vaccines Show Effectiveness Against Emerging COVID Variants

Two COVID-19 vaccines appear to work well against a rapidly spreading coronavirus variant that arose in California, but less effective against a variant that first emerged in South Africa, researchers report.

No Proof COVID Vaccines Can Trigger Guillain-Barré Syndrome

Two people in the Johnson & Johnson COVID-19 vaccine trial developed Guillain-Barré syndrome, but it's highly doubtful the vaccine is to blame, according to a just-published case study.

Although both people were in the same trial, one was given the vaccine and the other was given a placebo of saline solution.

"That strengthens the possibility that the case in our report may have be...

A Few People With COVID Went a Crowded Bar: Here's What Happened

COVID-19 is so contagious that even a single breach of social distancing measures can have far-reaching consequences.

A case in point: An explosion of new COVID-19 cases traced to five people who joined in on a bar's opening night in rural Illinois in February.

Four of the five who attended the crowded gathering (the bar's capacity was 100 people) were already experiencing symptom...
