The current theory holds that bats are the source (technically: the “reservoir”) of SARS Cov2, the virus that causes the disease known as COVID-19. Other research points to pangolins as a possible host for SARS CoV2, but where do the bats or the pangolins get it from? What do they have in common?
Before the COVID-19 outbreak was publicized in late 2019 I was following the ongoing Ebola outbreaks in Africa. It’s particularly interesting that bats have also been identified as the reservoir for the Ebola virus. Now Ebola, like other viruses, seems to pop up every so often, but why is that? It occurred to me that certain insects such as cicadas emerge on a regular schedule. Could there be a connection between insects, especially those insects with potentially irregular population surges such as cicadas, and these viruses? Periodical cicadas  of eastern North America have 13 and 17 year cycles where they emerge from the ground in large numbers providing a feast for many animals including birds and bats which typically leads to a subsequent surge in populations. Cicadas are native to most regions of the world including Africa and South East Asia, but most cicada species emerge on an annual basis – at least the known species. Presumably there are other insects that have similar periodic or aperiodic emergence or “upsurge” behavior such as locusts (which emerge from eggs in the soil) that might correlate with the virus outbreaks. As it turns out, pangolins are native to Africa and South East Asia and they are insectivorous . In 2003 the SARS virus was isolated in several masked palm civets and raccoon dogs (both of which are omnivores) that were found in a live-animal market in Guangdong, China . Could it be that the true reservoir for viruses such as SARS Cov-2 and Ebola is actually certain insects on which birds, bats, pigs and other animals feed?
