[8] [10] In 2020, reassortment (genetic "swapping") between these H5-2.3.4.4b viruses and other strains of avian influenza led to the emergence of a H5N1 strain with a H5-2.3.4.4b gene. [8] The virus then spread across Europe, first detected there in the autumn of 2020 before spreading to Africa and Asia. [1]

Onchocerciasis (river blindness) is the world's second leading cause of infectious blindness. It is caused by the nematode Onchocerca volvulus, which is transmitted to people via the bite of a black fly. The current WHO goal is to increase the number of countries free of transmission from 4 (in 2020) to 12 in 2030. [109]

[111] [168] The BBC also made it clear that the genetic sequences of the virus, as far as is known, date back to a West African strain. [111] Some online misinformation also included claims that the COVID-19 vaccine included mpox or that mpox was going to be used to justify new widespread lockdowns akin to those that occurred during COVID-19.
