What causes a virus to change and how to stop stronger Covid-19 variants from emerging


When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes.

Stopping the spread at the source remains key. Current measures to reduce transmission – including frequent hand washing, wearing a mask, physical distancing and avoiding crowded places or closed settings – continue to work against new variants by reducing the amount of viral transmission and therefore also reducing opportunities for the virus to mutate.


  1. If we closed all borders it sounds like we could stop the spread. Why don’t we add that to physical distancing, hand washing, mask wearing and vaccinations? Are we serious about this or not?

  2. WHO Director General Tewodro Adhanom must immediately stop his double standard pretending to be humanitarian in WHO and messing up Ethiopian life with his political inclination to Dead Junta called TPLF. He can not bury truth soon will flourish since I am collecting both audio, video and physical evidences.

  3. It still holds a doubt on the reason why P.1 and B.1.153 had come up with so many mutations at once. Could it be the virus has passed from humans to wild animals and then came back to humans? Are there wild animals carrying the SARS-CoV-2 in the jungle or the savanna right now?

  4. This south african variant is considered more potent mutation of covid19, as we all know that south african is the capital of virus prone region. Awaits, that this could be more contagious than UK variant and even more dreadful. It immensely show more complication in our health system. And besides coronavirus mutation will never stop! it will continue developing new qualities in it and keep mutating until it become more and more life threatening,

  5. Well we can stop all of this in just one day. By getting rid of the organisations who are guilty for all of this. Like you guys for example.
