Researchers are racing to understand the latest monkeypox outbreaks — from their origins to whether they can be contained.
because the monkeypox virus has emerged in separate populations across multiple countries, and there is no obvious link between many of the clusters, raising the possibility of undetected, local transmission of the virus.
The current sequences are most similar to those from a smattering of monkeypox cases that arose outside of Africa in 2018 and 2019 and that were linked to travel in western Africa.
Palacios says another reason is that few resources have been dedicated to genomic surveillance efforts in Africa, where monkeypox has been a public-health concern for many years. So virologists are flying somewhat blind right now, because they have few sequences to which they can compare the new monkeypox sequences, he says.
