Scientists have uncovered why Zika virus may specifically target neural stem cells in the developing brain, potentially leading to microcephaly.

Once a rare tropical disease, cases of Zika virus have now been reported across 89 countries and territories. So, what is Zika, how does it spread and what can be done to…

Researchers have identified the dose of dengue virus in human blood that is required to infect mosquitoes when they bite. Mosquitoes are essential for transmitting the virus…

Covid-19 alerted the world to the devastating potential of pandemics in the 21st century. Photojournalist Hugh Kinsella Cunningham and writer and public health professional,…

A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples…

Researchers have identified a new virus in patients with severe brain infections in Vietnam. Further research is needed to determine whether the virus is responsible for the…

A study published in the journal ‘Retrovirology’ has failed to find evidence of a link between chronic fatigue syndrome and a recently discovered virus.

Scientists have uncovered clues as to how our genomes became riddled with viruses. The study, supported by the Wellcome Trust, reveals important information about the so-…

Six months on from the first case of COVID-19, the pandemic is accelerating and spreading into new areas. Jeremy Farrar talks about the lessons we learned and the long-term…

As COVID-19 continues to spread around the world, a global community of researchers are working to find out more about the virus and assess what research needs to be done to…

The level of immunity to the recently circulating H7N9 influenza virus in an urban and a rural population in Vietnam is very low, according to the first population-level…

Scientists have found the ‘key’ that HIV uses to enter our cells’ nuclei, allowing it to disable the immune system and cause AIDS. The finding, published today in the open…

The Ebola virus, captured in watercolour and ink, has been selected as the overall winner for the 2016 Wellcome Image Awards.

The rapid evolution of HIV, which has allowed the virus to develop resistance to patients’ natural immunity, is at the same time slowing the virus’s ability to cause AIDS,…

Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural…

An inexpensive new test for the detection of Hepatitis B virus has been given regulatory approval for use in the European Union. The test delivers accurate results while you…

Wellcome is pledging up to US$100m (£70m/€80m) to accelerate Covid-19 research and development to ensure science keeps pace with the virus.

Interim results from the Guinean phase III trial of the Ebola vaccine known as VSV-EBOV, co-funded by the Wellcome Trust, indicate that it is highly effective against the…

A clinical trial of an experimental antiviral treatment for Ebola, funded by the Wellcome Trust, has been stopped following a significant fall in new cases of infection with…

A rapid, point-of-care diagnostic test for the Ebola virus will be trialled in the coming weeks at the Ebola treatment centre in Conakry, Guinea. The trial is one of six…
