As virologists around the world race to investigate the latest SARS CoV2 variant of concern, the UN’s World AIDS Day this week reminds us of the other global pandemic raging for some 40 years. Much of the work achieved over the last two years on SARS CoV2 has been achieved because of the investment made into, and the understanding gained from, HIV research over the last two decades. But to what further extent do they overlap in the population? There is a theory that the omicron variant, displaying so very many mutations compared to previous variants, might well have been incubated in a person suffering from a compromised immune system, possibly due to HIV, in whom the covid virus was able to linger longer than in fitter individuals. Prof. Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, is one of many virologists who transferred from HIV to coronavirus research, and hers, like hundreds of labs around the world, is racing to clone the parts of
