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.
It’s not spreading widely, and it’s not at Australia’s doorstep. The tools we have in place work against the coronavirus.
Nigeria’s academic community is mourning the death of virology professor and leading researcher, David Olufemi Olaleye.
New DNA evidence shows humans may have been battling coronaviruses for longer than recorded history.
The research community is taking a closer look at the lab-leak hypothesis for the origin of COVID-19, prompting discussion about the risks and benefits of engineering viruses.
We recently heard reports of a new and dangerous ‘hybrid’ variant circulating in Vietnam. There is such as a thing as a hybrid viral variant — but this doesn’t appear to be it.
