Virology

Virology is the study of viruses and virus-like agents: their structure, classification and evolution, their ways to infect and exploit cells for virus reproduction, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy.

What is Virology?

Virology is the study of viruses and virus-like agents, including, but not limited to, their taxonomy, disease-producing properties, cultivation and genetics.

Co-infection with MRSA ‘superbug’ could make COVID-19 outcomes even more deadly

Global data shows nearly 10 per cent of severe COVID-19 cases involve a secondary bacterial co-infection – with Staphylococcus aureus, also known as Staph A., being the most common organism responsible for co-existing infections with SARS-CoV-2.

New SARS-CoV-2 Omicron XBB.1.5 variant has high transmissibility and infectivity, study finds

COVID-19 has caused significant global panic after its rapid emergence more than 3 years ago. Although we now have highly effective vaccines against the SARS-CoV-2 virus, which causes COVID-19, scientists continue to study emerging SARS-CoV-2 variants in order to safeguard public health and devise global preventive strategies against emerging variants.
