The strongest benefits were seen in women who ate more plant-based foods, fish, and olive oil while cutting back on red meat and saturated fats. Their risk dropped across all major stroke types, including bleeding strokes, which are less commonly studied. The findings suggest diet may be a powerful but overlooked factor in stroke prevention.

A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments confirmed that fever cripples human-origin flu but not avian strains, especially those with avian-like PB1. These findings highlight how gene swapping could fuel future pandemics.

But during the 2022 global outbreak, mpox began spreading readily between people. A new study now shows the virus was circulating long before then.

This was the first time many had ever heard of the virus, but since it was first identified in 1976, there have actually been more than 20 serious Ebola incidents. Thankfully, none of them had the global reach of the coronavirus. Ebola has not been eradicated, however. This deadly virus, which causes severe hemorrhagic fever in humans and has a fatality rate of about 50%, is still at large and could thus still cause a major outbreak, unless further research finds an effective solution.

For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, and people with HIV in particular, should therefore receive the second dose of the vaccine as recommended.

It's one way the virus crosses the placental barrier, transmitting from mother to fetus during pregnancy without raising alarm in the immune system. The team also demonstrated, for the first time, that one specific Zika protein -- non-structural protein 1 (NS1) -- is responsible for the formation of the nanotubes.

The study identifies new cell types within the skin that are targeted by EBOV during infection and shows that human skin specimens actively support EBOV infection. Overall, the findings, suggest that the skin's surface may be one route of person-to-person transmission.

In a new study, researchers identified a protein in mammals that welcomes arteriviruses into host cells to start an infection. The team also found that an existing monoclonal antibody that binds to this protein protects cells from viral infection.

This finding was made more than 500 km south of the previously known range. 'We were surprised that such high proportion of the relatively few voles that we caught were actually carrying a hantavirus that makes people ill', says infection disease doctor.

A new study, however, suggests that the number of 'hidden' infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.

Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.

The findings offer hope for patients affected by this potentially deadly disease.

New research includes a genetic analysis of the virus samples, isolated from ticks collected in central Georgia.
