African scientists baffled by unusual spread of monkeypox cases in Europe, US
[IsraelTimes] European officials exploring whether disease is being sexually transmitted, something not seen before in Africa where most people are infected by contact with rats and squirrels.Scientists who have monitored numerous outbreaks of monkeypox in Africa say they are baffled by the disease’s recent spread in Europa  ...the land mass occupying the space between the English Channel and the Urals, also known as Moslem Lebensraum...and North America. Cases of the smallpox-related disease have previously been seen only among people with links to central and West Africa. But in the past week, Britannia, Spain, Portugal, Italia, US, Sweden and Canada all reported infections, mostly in young men who hadn’t previously traveled to Africa. La Belle France, Germany, Belgium and Australia confirmed their first cases Friday, while Israel said it had its first suspected case too. "I’m stunned by this. Every day I wake up and there are more countries infected," said Oyewale Tomori, a virologist who formerly headed the Nigerian Academy of Science and who sits on several World Health Organization advisory boards. "This is not the kind of spread we’ve seen in West Africa, so there may be something new happening in the West," he said. To date, no one has died in the outbreak. Monkeypox typically causes fever, chills, rash and lesions on the face or genitals. WHO estimates the disease is fatal for up to one in 10 people, but smallpox vaccines are protective and some antiviral drugs are being developed.
Nigeria reports about 3,000 monkeypox cases a year, WHO said. Outbreaks are usually in rural areas, when people have close contact with infected rats and squirrels, Tomori said. He said many cases are likely missed. Dr. Ifedayo Adetifa, head of the country’s Center for Disease Control, said none of the Nigerian contacts of the British patients have developed symptoms and that investigations were ongoing. WHO’s Europe director, Dr. Hans Kluge, described the outbreak as "atypical," saying the disease’s appearance in so many countries across the continent suggested that "transmission has been ongoing for some time." He said most of the European cases are mild. On Friday, Britannia’s Health Security Agency reported 11 new monkeypox cases, saying "a notable proportion" of the infections in the UK and Europe have been in young men with no history of travel to Africa and who were gay, bisexual or had sex with men. Authorities in Spain and Portugal also said their cases were in young men who mostly had sex with other men and said those cases were picked up when the men turned up with lesions at sexual health clinics. Experts have stressed they do not know if the disease is being spread through sex or other close contact related to sex. Nigeria hasn’t seen sexual transmission, Tomori said, but he noted that viruses that hadn’t initially been known to transmit via sex, like Ebola, were later proven to do so after bigger epidemics showed different patterns of spread. Happi also pointed out that the suspension of smallpox vaccination campaigns after the disease was eradicated in 1980 might inadvertently be helping monkeypox spread. Smallpox vaccines also protect against monkeypox, but mass immunization was stopped decades ago. "Aside from people in west and Central Africa who may have some immunity to monkeypox from past exposure, not having any smallpox vaccination means nobody has any kind of immunity to monkeypox," Happi said.
