Contents: 

Tags: 

This article provides an overview of virus mutations, the current variants from the UK and South Africa, how the immune system works on pathogen proteins, and whether all this has implications on the efficacy of the current vaccines.

Users on social media have been sharing news that China is using Anal Swabs for detecting Coronavirus infections. While this is true, it seems that this will not be applied to everyone being tested.

SARS-CoV-2, the Coronavirus that causes COVID-19 and is responsible for the 2020 pandemic, is known to enter cells via the ACE2 receptor (see this video on the Renin-Angiotensin system).
