This is why the Oropouche virus is a cause for concern

(CNN) – A little-known virus is causing widespread concern, prompting the U.S. Centers for Disease Control and Prevention to raise the alarm about the Oropouche virus after travel-related cases were reported in the U.S. and Europe.

It is a disease transmitted by insect bites, particularly those of midges, a tiny species of fly, and some mosquitoes.

As of August 1, more than 8,000 cases of the Oropouche virus have been reported this year.

Most cases have occurred in South America, but infections are spreading to other countries where they have never occurred before.

At least 21 US travelers returning from Cuba have tested positive for the virus.

“The disease can make you very sick within seven days,” said Dr. Lyssette Cardona of the Cleveland Clinic.

Cardona said symptoms include sudden fever, severe headaches and muscle and joint pain. In rare cases, the disease can infect the nervous system and cause meningitis and encephalitis.

“Fortunately, most people can recover from the disease, although it can return after a few days,” she said.

Cardona said the Oropouche virus is particularly dangerous for pregnant women because the infection could potentially spread to the fetus and cause harm since there is no vaccine.

The best protection is to prevent insect bites, wear loose-fitting, long-sleeved shirts and pants, use an EPA-approved insect repellent approved to control flies and biting flies, and stay in air-conditioned rooms to keep insects out.

“Most cases in the United States have been imported through foreign travel, but we remain very vigilant due to recent cases in Cuba,” Cardona said.

According to the CDC, there is currently no evidence of local transmission of the Oropouche virus in the United States

All cases were brought into the country by travelers, but the CDC said the current outbreak raises concerns that Oropouche could spread in the United States.

Scientists said mosquito species found in both parts of the country could potentially transmit the Oropouche virus.
