There is a line of thought that Covid-19 arose from gain-of-function genetic engineering research at the Wuhan lab, which was funded in part by the US. Then there are Russian claims of Ukraine bioweapons labs that were discovered. Other claims that have been covered at this blog indicate that monkeypox was also genetically modified, since the current outbreak does not fit the West African pattern.
As discussed by Children Health Defense.com, gain of function genetic research is being conducted by labs across the world. As discussed, one virologist modified the H5N1 avian influenza virus, which is not readily spread from person-to-person, so that the virus could spread rapidly between humans, killing over 60 percent of people. One must wonder how many other Dr Frankenstein experiments are being conducted in labs across the world.
