Thank you for all the valuable updates.
A former Chitambo District Medical Officer alerted me to the suggestion that chloroquine is being considered as a possible treatment for coronavirus. Is there any truth in this and could it be a factor in the apparent lack of spread amongst Saharan Africans? Are current antimalarials chloraquine based?
I saw this information on PubMed, so presumably it is a serious proposition?
