      I’ve researched four infectious diseases – a parasitic infection called schistosomiasis, which is spread by snails, and two sexually transmitted infections – HIV and syphilis. They’re all nasty diseases in different ways – schistosomiasis infects more people (over 200 million people) but HIV causes more deaths (770000 in 2018).
