Scientists in South Africa have been investigating what they say is the "highly plausible hypothesis" that new Covid-19 variants could be linked to mutations in those whose immune systems have already been weakened - such as, but not limited to, people with untreated HIV.

It's been observed that coronavirus can linger for many months in patients who are HIV positive but who have not had access to medicines in order to remain healthy.

Professor Linda-Gail Bekker is director of the Desmond Tutu HIV Centre in Cape Town, South Africa - and is past president of the International Aids Society. She's also been involved in this research. She says this shows how important it is that all people, rich and poor, are given proper medical treatment for both HIV and Covid.

"There are many reasons why people may be immunocompromised and I think it really does underline the need to ensure we get vaccination to every corner of the world for Covid, to ensure that we do the best for people's immunity, wherever they are."
