Cow udders may provide a hotspot for bird flu and human flu viruses to mingle. The prospect of an outbreak of avian influenza among dairy cattle triggering a pandemic in humans is one step closer than ...

Canine coronavirus and influenza D are two zoonotic viruses that researchers say have “considerable potential” for causing future epidemics in people. In an article published recently in Emerging ...

Distinguishing between self and non-self is a critical ability of the immune system. Some pathogens have evolved proteins that resemble those of their host, a mechanism called molecular mimicry, in an ...

A new year might mean new viral threats. Old viruses are constantly evolving. A warming and increasingly populated planet puts humans in contact with more and different viruses. And increased mobility ...

Around 8 percent of human DNA is made up of genetic sequences acquired from ancient viruses. These sequences, known as human endogenous retroviruses (or Hervs), date back hundreds of thousands to ...

The avian flu virus isolated from a hospitalized teenager in Vancouver has mutations in key areas that could help the virus spread more easily in humans, scientists say. There is no indication that ...

New research reveals that the bird flu viruses may be capable of replicating at temperatures higher than an average fever, a key bodily defense mechanism against severe infection. The international ...

What sets these viruses apart is their unusual ability to insert their genetic material into human chromosomes. This allows the virus to stay inactive for long periods and, in rare cases, be passed ...

Scientists have long known that a significant portion of the human genome is made up of the remnants of ancient viruses; these sequences are a subset of transposable elements known as endogenous ...
