The United States Centers for Disease Control and Prevention (CDC) said on Friday it was aware of more than 700 global cases of Monkeypox, including 21 in the United States, with investigations now suggesting it is spreading within the country. . Of the first 17 cases, 14 would be associated with travel. All patients are recovering or have recovered, and no cases have been fatal. “There have also been cases in the United States that we know are linked to known cases,” Jennifer McQuiston, deputy director of the CDC's Division of High Consequence Pathogens and Conditions, told reporters. “We also have at least one case in the United States who does not have a travel link or does not know how he acquired his infection,” she added. Canada also released new figures on Friday, counting 77 confirmed cases – almost all detected in the province of Quebec, where the vaccines were delivered. As of Wednesday, the World Health Organization (WHO) reported 550 cases of Monkeypox in 30 countries. WHO Director General Tedros Adhanom Ghebreyesus had said that the sudden appearance of Monkeypox in several countries around the world indicates that the virus has been spreading undetected for some time outside West African countries and center where it is usually located. The virus may have been transmitted for months or years undetected, although investigations are ongoing and there are no clear answers yet, according to Dr Rosamund Lewis, WHO technical lead for monkey pox. “We don't really know if it's too late to contain the virus. What the WHO and all member states are trying to do is prevent the spread,” Lewis also said at a press conference in Geneva on Wednesday. Contact tracing and isolation of patients with monkeypox are key to stopping the spread, she said. Monkeypox is a rare disease related to smallpox but less severe, causing a spreading rash, fever, chills and body aches, among other symptoms. Generally confined to West and Central Africa, cases have been reported in Europe since May and the number of affected countries has since increased.
