Washington: The US government has declared the monkeypox outbreak a public health emergency after spike in cases which topped 6,600, according to health officials.
The decision is likely to speed up the distribution of vaccines, treatments and federal resources to curb the spread of the virus.
It comes less than a fortnight after the World Health Organization (WHO) issued its highest emergency alert following a worldwide surge in monkeypox cases.
Public health officials told BBC the disease is particularly prevalent among men with same sex partners.
The declaration on Thursday comes amid reports that vaccines and treatments for monkeypox are in short supply across the country, the BBC added
The Department of Health and Human Services last week said it has ordered more than five million doses, to be delivered until next May.
Earlier this week, the White House also announced the appointment of a team to co-ordinate and oversee the national monkeypox response. It includes Demetre Daskalakis, a New York physician who has led successful initiatives to curb the spread of HIV in the US.
A quarter of the monkeypox cases have appeared in the state of New York, which declared its own state of emergency over the disease last week.
The two states with the next highest caseloads – California and Illinois – declared states of emergency earlier this week.
More than 26,000 cases have been confirmed worldwide this year, data from the US Centers for Disease Control and Prevention (CDC) shows.
Some public health experts have expressed concern the emergency declaration could further stigmatise the disease. Although anyone can catch monkeypox, the outbreak has been largely concentrated among men.
But it is not purely a sexually transmitted infection (STI), and can also be passed on by close contact with an infected person.
The virus typically causes pimple-like rashes, which can be extremely itchy and painful, to develop and spread across the body, as well as other complications.
Infections are usually mild and clear up on their own in adult patients without treatment or hospitalisation – but the WHO has warned that young children have died at higher rates from the disease.
Officials in the US and elsewhere have recommended that people at the highest risk of exposure – including some gay and bisexual men, as well as some healthcare workers – should get the jab on a priority basis, the BBC report added.
