The current outbreak of Zaire Ebola virus in Western Africa is the largest ever recorded. More than 1800 people have been infected and nearly 1000 people have died. But while drug therapies are close to…

The current epidemic of Ebola, which started in March 2014, has reached Lagos, the most populous city in the most populous country in Africa. This is a huge concern. And while Margaret Chan, director-general…
The current West African ebolavirus outbreak, which has now reached more than 1,000 cases and resulted in more than 800 deaths, is a reminder of the often unpredictable nature of viruses and the difficulties…
Our understanding of Ebola has increased considerably since outbreaks of a mysterious haemorrhagic fever caused by an unknown virus first occurred in Southern Sudan and the Democratic Republic of Congo…
Scientists have revealed the structure of human-like proteins produced by viruses to fool our immune system. Researchers…
A newly discovered virus may be living in the stomach of half the world’s population. The virus could be one of the most…
US researchers have determined a potential marker to identify patients prone to hepatitis C relapse after antiviral therapy…
An outbreak of parechoviruses in Queensland is causing concern because of the severity of the illness among infants younger than three months old. Dozens of cases have been detected in Australia since…
Here is a puzzle for you. Why did shares in Yahoo! slide by nearly 10% in the days before Heartbleed was announced and then recover after the main news items broke? It has long been the case that security…
As a virologist, I am often asked when science will come up with a solution to stop deadly viruses, such as the current Ebola outbreak in Guinea. With collaborators, I’ve helped design and test over a…
You may have seen recently that scientists recovered and “revived” a giant virus from Siberian permafrost (frozen soil) that dates back 30,000 years. The researchers raised concerns that drilling in the…
A virus that commonly causes diarrhoea in children may accelerate the development of type 1 diabetes, new research shows…
Viruses have traditionally been mankind’s enemies, causing disease and often mutating out of the reach of our medicines. But now a new technology is conscripting them into doing good. Viral vectors show…
It may seem like a fairly fundamental question, but there is still debate over whether viruses should be considered a form of life. The diversity of viral infections is immense. Viruses cause everything…
Last October, scientists in California sequenced the DNA for the “type H” botulinum toxin. One gram of this toxin would be sufficient to kill half a billion people, making it the deadliest substance yet…
As viruses go, Ebola is one that strikes particular fear. It’s infectious and four out of the five identified strains can cause severe hemorrhagic fever, which in later stages leads to bleeding from the…
As a virologist working in the Gambia, the idea of a portable microscope that uses fluorescent imaging and can be attached to your smartphone to detect viruses and bacteria in the field sounds amazing…
At least 320,000 new and undiscovered viruses could be circulating throughout mammals and awaiting discovery. A study conducted…
Plankton might cause the spread of a herpes-like virus in oysters. The oyster virus is a branch of the herpes virus, but…
Some viruses are like tiny powerhouses. They are only nanometers in size, but their insides are jam-packed with DNA that is so highly pressurised that it explodes out during infection. Herpes simplex 1…
