B virus is a biosafety category 4 virus. That is, the same level as Ebola and unknown new pathogens.

The JN.1 variant has become dominant in Australia and around the world, causing large waves of infections. Here’s what we know about it so far – and why it’s so important.
We tend to just think of viruses in terms of their damaging impacts on human health and lives. But viruses can also be used to benefit human health, agriculture and the environment.
Viruses can get into cells in several ways. Figuring out how to stop them from entering in the first place is a key to developing better vaccines and stopping future pandemics.
Researchers discovered a satellite virus latching onto the neck of another virus called MindFlayer. Studying the viral arms race between similar viruses could lead to new ways to fight infections.
It can be difficult to an appointment to see your GP. So when should you make the effort to see a GP for a prescription for influenza antivirals? And how effective are they?
We know from other viruses that viral fragments can remain in different tissues for months or even years. This could be the case for long COVID.
From cancer immunotherapy and antibiotics to GMO crops and pandemic surveillance, gain of function is a cornerstone of basic research.
People with an active case of shingles have up to an 80% higher risk of stroke than those without. The increased risk is highest for patients under 40.
COVID-19 causes lung injury and lowers oxygen levels in patients because the SARS-CoV-2 virus attacks cells’ mitochondria. This attack is a throwback to a primitive war between viruses and bacteria.
Financial support for science and research in Nigeria remains pathetic. This has led to the deterioration in the quantity and quality of trained virologists at universities.
Phages, or viruses that infect bacteria, can lie dormant within chromosomes until they’re triggered to replicate and burst out of their hosts.
Patients with low HIV viral loads are just as likely to harbour HIV variants with drug resistance mutations as those with high viral loads.
Animal reservoirs and people who experience chronic COVID infections could potentially see the emergence of new variants. But these variants aren’t necessarily cause for concern.
You know the symptoms because you’ve already had COVID once. So what can you expect when you’re reinfected? And why does it happen?
Masks definitely catch some of the virus laden aerosols and droplets - and that will reduce transmission between people and the number of cases of COVID-19.
Each year in spring and summer, waterbirds mingle on their breeding grounds in Siberia and mix their flu viruses, creating new variants they then bring to Europe, Asia and Africa.
Viruses have gotten a bad rap for the many illnesses and pandemics they’ve caused. But viruses are also genetic innovators – and possibly the pioneers of using DNA as the genetic blueprint of life.
Delta is more contagious and appears to be more deadly. And it’s more likely to land those infected in hospital and intensive care. Here’s what the latest evidence says about the dominant variant.
It’s unclear whether the patients were already predisposed to these diseases, or the infection unmasked a process that had already begun. Or perhaps the infection triggered a completely new illness.
