Texas state and federal health officials confirmed a case of human monkeypox in a U.S. resident who recently traveled from Nigeria to the United States.
The person is currently hospitalized in Dallas. CDC is working with the airline and state and local health officials to contact airline passengers and others who may have been in contact with the patient during two flights: Lagos, Nigeria, to Atlanta on July 8, with arrival on July 9; and Atlanta to Dallas on July 9.
Travelers on these flights were required to wear masks as well as in the U.S. airports due to the ongoing COVID-19 pandemic. Therefore, it’s believed the risk of spread of monkeypox via respiratory droplets to others on the planes and in the airports is low. Working with airline and state and local health partners, CDC is assessing potential risks to those who may have had close contact with the traveler on the plane and specific settings.
Monkeypox is a rare but potentially serious viral illness that typically begins with flu-like illness and swelling of the lymph nodes and progresses to a widespread rash on the face and body. Most infections last 2-4 weeks. Monkeypox is in the same family of viruses as smallpox but causes a milder infection. In this case, laboratory testing at CDC showed the patient is infected with a strain of monkeypox most commonly seen in parts of West Africa, including Nigeria. Infections with this strain of monkeypox are fatal in about 1 in 100 people. However, rates can be higher in people who have weakened immune systems.
Prior to the current case, there have been at least six reported monkeypox cases in travelers returning from Nigeria (including cases in the United Kingdom, Israel, and Singapore). This case is not related to any of these previous cases. In the United Kingdom, several additional monkeypox cases occurred in people who had contact with cases.
Experts have yet to identify where monkeypox hides in nature, but it’s thought that African rodents and small mammals play a part in spreading the virus to people and other forest animals like monkeys. People can get monkeypox when they are bitten or scratched by an animal, prepare wild game, or have contact with an infected animal or possibly animal products. Monkeypox can also spread between people through respiratory droplets, or through contact with body fluids, monkeypox sores, or items that have been contaminated with fluids or sores (clothing, bedding, etc.) Human-to-human transmission is thought to occur primarily through large respiratory droplets. Respiratory droplets generally cannot travel more than a few feet, so prolonged face-to-face contact is required.
Most monkeypox outbreaks have occurred in Africa. In addition to Nigeria, outbreaks have also been reported in nine other countries in central and western Africa since 1970.
