Washington D.C., and New York state have the highest monkeypox case rates in the U.S

 

The number of monkeypox cases reported in the U.S. has tripled in the past three weeks, according to data from the CDC, as the virus strengthens its hold on the country.⁠
More than 2,300 cases had been confirmed as of Wednesday afternoon, up from 700 on July 8. ⁠ Monkeypox is an infectious viral disease that can occur in humans and some other animals. Symptoms include fever, swollen lymph nodes, and a rash that forms blisters and then crusts over. The time from exposure to onset of symptoms ranges from 5 to 21 days. The duration of symptoms is typically 2 to 4 weeks. There may be mild symptoms, but it may occur without any symptoms being known. The classic presentation of fever and muscle pains, followed by swollen glands, with lesions all at the same stage, has not been found to be common to all outbreaks. Cases may be severe, especially in children, pregnant women or people with suppressed immune systems.

The disease is caused by monkeypox virus, a zoonotic virus in the genus Orthopoxvirus. The variola virus, causative agent of smallpox, is also in this genus. Of the two types in humans, the West African type causes a less severe disease than the Central African (Congo Basin) type. It may spread from infected animals by handling infected meat or via bites or scratches. Human to human transmission can occur through exposure to infected body fluids, contaminated objects, by small droplets and possibly the airborne route. People can spread the virus from the onset of symptoms until all the lesions have scabbed and fallen off; with some evidence of spread for more than a week after lesions have crusted. Diagnosis can be confirmed by testing a lesion for the virus's DNA.

There is no known cure. A study in 1988 found that the smallpox vaccine was around 85% protective in preventing infection in close contacts and in lessening the severity of the disease. A newer smallpox and monkeypox vaccine based on modified vaccinia Ankara has been approved, but with limited availability. Other measures include regular hand washing and avoiding sick people and other animals. Antiviral drugs, cidofovir and tecovirimat, vaccinia immune globulin and the smallpox vaccine may be used during outbreaks. The illness is usually mild and most of those infected will recover within a few weeks without treatment. Estimates of the risk of death vary from 1% to 10%, although very few deaths as a consequence of monkeypox have been recorded since 2017.

Monkeypox was first identified as a distinct illness in 1958 among laboratory monkeys in Copenhagen, Denmark. Several species of animal are suspected to act as a natural reservoir of the virus. Although it was once thought to be uncommon in humans, cases have significantly increased since the 1980s, possibly as a result of waning immunity since the stopping of routine smallpox vaccination. The first cases in humans were found in 1970 in the Democratic Republic of the Congo (DRC). There have been sporadic cases in Central and West Africa, and it is endemic in the DRC. The 2022 monkeypox outbreak represents the first incidence of widespread community transmission outside of Africa, which was initially identified in the United Kingdom in May 2022, with subsequent cases confirmed in at least 20 countries in Europe, North America, South America, Asia, Africa, and Australia
