Fungal viruses have been important in reducing the impact of fungal diseases on chestnuts in Europe.
Technology is allowing scientists to better understand fungal viruses, with the aim of managing them more effectively.

Cuba's access to internationally produced vaccines was nearly impossible due to the U.S. blockade. Its decision to make its own vaccines stands to pay off handsomely.
Pollen can suppress how the body’s immune system responds to viruses.

As climate change drives pollen counts upward, that could potentially result in greater human susceptibility to other viruses, as well.

As the world has focused on the COVID-19 pandemic, other microbial foes are waging war on humans. Antibiotic-resistant bacteria pose a growing threat. But viruses may defeat them.
For many, distinguishing between fact and fiction is difficult.

With the vaccines now being administered at sites around the US, it is important to address misinformation surrounding the effort.
Fatigue, brain fog, breathing problems and many other COVID-19 symptoms can persist for months.

'Long COVID' – in which people have symptoms lasting more than a few weeks – is turning out to be very common. People hospitalized for COVID-19 are at highest risk, but they aren't alone.
Occasionally, a mutation will give the virus a better chance of surviving and reproducing itself, and will result in a new population (known as a new lineage)
One of Tanzania’s approaches to managing the spread of the new coronavirus is through prayer.

The pandemic will not end for anyone, anywhere until it is controlled in every country. Tanzania’s approach will make it that much harder for normality to return.
Study shows that the Novavax vaccine is effective against the dominant variant of COVID-19 in South Africa.

The results indicate that the vaccine efficacy in the UK was 89% for individuals who received at least two doses of vaccine. In South Africa, the vaccine efficacy was 60% in people without HIV.

Is it time for some scientists to turn back to pre-COVID-19 research?

Ever since the 2001 SARS outbreak and H5N1 avian flu in 2003, we’ve developed tools to monitor diseases that transmitted from animals to humans. But what does a large-scale roll-out entail?
Wouldn’t it be nice if one shot could protect you for life?

You need a new shot every year because current flu vaccines provide limited and temporary protection. But researchers' new strategy could mean a one-and-done influenza vaccine is on the way.
There are more viruses in the ocean than stars in the Milky Way – and they're fundamental to Earth's biodiversity.
The microbes living in the gut are key to good health.

The microbes in your gut influence how your immune system reacts to bacteria and viruses. A severe immune reaction is deadly; a small one lets the virus win. The right balance may depend on your diet.

Multiple COVID-19 variants are circulating around the world and becoming more common. These mutations can alter the ability of the virus to take hold and replicate within our cells.
A wild mink in Utah was the first wild animal in the U.S. found with COVID-19.

COVID-19 has been found in pets, zoo animals and in a wild mink in Utah. Monitoring wildlife for COVID-19 is important for animals and humans, both of whom face risks from a jumping virus.
Vampire bats, a commonly deltavirus-infected host, feed on the blood of other mammals.
The genome of hepatitis D doesn’t resemble any known virus, making its origin a mystery. But by mining virus sequences from genetic datasets, a new study may have found the answer.
Before the U.S. can return to some form of normal, a lot of people need to be vaccinated.

Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
I am a physician, and I just got my first shot of the Pfizer COVID-19 vaccine.
With vaccines forthcoming for most Americans, many groups, including expectant mothers, are wondering if the vaccine is safe for them and their babies. A physician-scientist explains.
