It is unclear how some people recently diagnosed with the disease became infected with the monkeypox virus or how it is likely to spread
More new human cases of monkeypox have been identified worldwide, with dozens reported in the U.K. alone. The increase comes after previous evidence had suggested there was unknown transmission of the monkeypox virus within the country’s population, according to the U.K. Health Security Agency (UKHSA). Monkeypox is thought to originate in rodents in Central and West Africa, and it has repeatedly jumped to humans. Cases outside Africa are rare and have so far been traced to infected travelers or imported animals.
