America’s monkeypox tally rose to seven presumptive cases Tuesday, health chiefs revealed today as a man in Washington state and an individual in South Florida was probed for the virus that is rampaging globally.
Officials in Washington said a man in King County — which includes Seattle — tested positive for the family of viruses that includes monkeypox after recently returning from abroad. He is now isolating at home and awaiting confirmatory test results from the Centers for Disease Control and Prevention (CDC).
Health chiefs warn it is a ‘possibility’ that other cases will crop up in the state, although say they have found ‘no evidence’ of onward transmission so far.
Florida also revealed a second suspected case today in another individual from Broward County — which borders Miami. It was not clear whether this was linked to the first reported Sunday in the same county.
America now has six suspected cases of monkeypox, with one also in New York City and two in Utah. One case has been confirmed in Boston, Massachusetts, so far.
None of the individuals have been named, but the CDC revealed Monday that they were all male and had travelled internationally over the last month.
Globally, the total has surged to more than 170 cases confirmed in at least 20 nations — mostly in Europe — including the UK, France and Italy.
Cases are being disproportionately detected among gay and bisexual men, with experts suggesting the outbreak is linked to sex at two raves in Spain and Belgium.

The disease, first discovered in lab monkeys in the late 1950s, is usually mild but can cause severe illness in some cases. It can kill up to 10 percent of people it infects.
This outbreak is believed to be of the milder, West African, strain of the virus, which has a mortality rate of around one in every 100 cases.
Monkeypox has an incubation period of anywhere up to 21 days, meaning it can take three weeks for symptoms to appear. Symptoms include fever, headache, muscle aches, backache, swollen lymph nodes, chills and exhaustion.
A rash can develop, often beginning on the face, which then spreads to other parts of the body — including the genitals. The rash can look like chickenpox or syphilis, and scabs can form which then fall off.
In Washington local health chief Dr Jeff Duchin said there was currently ‘no evidence’ of further spread in the area — although did not rule it out.
‘The risk to the public is low,’ he said, ‘but it’s important for clinicians and the public to be aware of the symptoms and risk factors for monkeypox’.
More than 200 people, mostly health care workers, are currently being monitored for monkeypox infection in Massachusetts.
But the risk that the individuals have caught the virus is low, because this requires sustained skin-to-skin contact.
U.S. officials were monitoring six people for a potential infection after they sat within three rows of a case on a seven-hour flight from Nigeria to the UK. There has been no subsequent report that any tested positive.
Monkeypox is generally spread through touching infectious skin lesions, but can also be passed on through droplets in the air.
At a CDC briefing yesterday Dr John Brooks, a medical epidemiologist at the agency, said in this outbreak many patients had lesions in the genital area.
He added that in some instances they are being mistaken for a ‘very bad’ case of herpes.
It comes after the CDC said it had opened its vaccination stocks to treat ‘high risk’ people exposed to the virus.
More than 1,000 doses of Jynneous — a vaccine which can treat both monkeypox and smallpox — are now being given to high-risk individuals in the United States.
People receiving the shot can get their first jab shortly after potential exposure to bolster their immunity levels. They must also get a second jab within four weeks.
People who are infected with monkeypox often suffer from severe rashes, skin lesions and flu like symptoms. The virus kills around one-in-ten people it infects, though there is belief that the current strain making its way around the world has a mortality rate of one percent
The CEO of Bavarian Nordic — which makes the vaccine — revealed Tuesday they had been inundated with calls.
He told CNBC: ‘We are ramping up production as we speak and hopefully will be able to provide doses.
‘We have already provided some doses to some European countries, and we are doing so with more this week.’
