Unravelling the mystery that makes viruses infectious — ScienceDaily

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus ‘package up’ their genetic code, allowing them to infect cells. The findings, published today (Friday, 8 January) in the journal PLOS Pathogens by a team from the Universities of Leeds and York, open up the possibility that […]

COVID-19: when are you most infectious?

A close friend – let’s call him John – recently called, asking for advice. He woke up with severe muscle aches and fatigue. Understandably worried that it could be COVID-19, he asked whether he should go to work, run to get a test or stay home. Because he didn’t have other symptoms, such as a […]

Effect of climate change on infectious diseases unknown to half of the population

The transmission of specific infectious diseases have been altered by processes linked to climatic and environmental anomalies. An increase in infectious outbreaks is expected to be seen in mild climates due to global warming, and the alterations in climate patterns, such as El Niño, are modifying the presence, density, strength and dynamics of transmission of […]

Woman with COVID-19 sheds infectious virus for a record 70 days

A woman with COVID-19 in Washington state shed infectious virus particles for 70 days, meaning she was contagious during that entire time, despite never showing symptoms of the disease, according to a new report. The 71-year-old woman had a type of leukemia, or cancer of the white blood cells, and so her immune system was […]

Vaccine protects animals against tick-borne Powassan virus, an emerging infectious disease — ScienceDaily

Scientists at The Wistar Institute have designed and tested the first-of-its-kind synthetic DNA vaccine against Powassan virus (POWV), targeting portions of the virus envelope protein. A rapidly reemerging tick-borne disease, POWV has been reported to be fatal in 10% of infected people with detrimental neurological consequences including encephalitis and meningitis. This new POWV vaccine candidate, […]
