Monkeypox, a rare form of the dangerous smallpox virus, has appeared in Connecticut. The patient was identified as a man between the ages of 40 and 49 from New Haven County.\u00a0 As of July 1, there were 460 cases nationwide, according to data maintained by the U.S. Centers for Disease Control. This past May, the first confirmed case in the United States in 2022 was reported across the border in Massachusetts. Of those 460 cases, the CDC reported 23 in Massachusetts, one in Rhode Island and 90 in New York state. Local news reports said at least four of those 90 cases were in Westchester County. Connecticut Department of Public Health Commissioner Manisha Juthani said the agency believes that the \u201crisk to Connecticut residents from this case is low,\u201d though \u201cthe United States is currently experiencing a monkeypox outbreak, and there will likely be additional cases in Connecticut in the weeks ahead.\u201d Here\u2019s what you need to know about monkeypox: What is monkeypox? Monkeypox is a virus in the same family as smallpox and cowpox, according to the Centers for Disease Control and Prevention. It was first discovered in Africa in 1958 when there was an outbreak among monkeys held for research, the CDC said. WHO said the first human case of monkeypox was found in a child in the Democratic Republic of the Congo in 1970. The first case was reported in the United States in 2003. How can someone catch monkeypox? While not entirely known, it is believed that the virus is carried through monkeys and rodents, according to the CDC. It can also be passed between humans through contact with bodily fluids, the CDC said. Cases found in the United States are often linked to international travel. Experts have said it is believed that sexual contact at two raves in Europe may have spread the virus, according to the Associated Press. \u201cWe know monkeypox can spread when there is close contact with the lesions of someone who is infected, and it looks like sexual contact has now amplified that transmission,\u201d Dr. David Heymann, who formerly headed WHO\u2019s emergencies department, told The Associated Press. What are the symptoms of monkeypox? According to officials, monkeypox presents similarly to smallpox, but often the symptoms are less severe. The initial symptoms include fever, head and muscle aches, swollen lymph nodes, chills and exhaustion, according to the CDC. Health officials said the virus takes between seven and 14 days to incubate, meaning it could be one to two weeks after an infection before symptoms start to show. About one to three days after the fever starts, an infected individual will develop a rash, or lesions, that spread from the face to the rest of their body, the CDC said. How is it treated? There is no defined treatment for monkeypox that is approved in the United States, according to the CDC. However, antiviral drugs and the smallpox vaccine are used to control outbreaks of the virus in the United States. How rare are cases of monkeypox? There are several thousand cases a year reported in African countries, according to the WHO. But outside those nations, outbreaks are rare, but have been seen in the United States, the United Kingdom and other countries. The largest outbreak in the United States impacted 47 people in 2003, according to the Associated Press. Where are the current outbreaks of monkeypox? The CDC reports there are over 5700 cases of monkeypox globally, spread across 52 countries. The larger outbreaks are currently in the United Kingdom, Germany and Spain.
