Unknown disease kills 143 in southwest Congo, local authorities say

The health ministry said that the remains of anyone who has died after experiencing similar symptoms should not be handled without the involvement of authorized health authorities, and it asked people to report any suspicious illnesses or unusual deaths. The office also advised people to avoid mass gatherings and observe basic rules of hygiene, including washing hands with soap and water.

Emergency public health officials have been dispatched to the region, according to the ministry.

The World Health Organization told NBC News that it is aware of reports of an unidentified disease and is working with local authorities.

“We have dispatched a team to the remote area to collect samples for lab investigations,” WHO spokesperson Tarik Jašarević said in an email.

The U.S. Centers for Disease Control and Prevention, which has an office in Congo, said it is aware of the situation and is providing technical assistance to a rapid response team dispatched by a local emergency operations center.

​

Anne Rimoin, an epidemiologist at the University of California, Los Angeles, who has worked in Congo since 2002, said diagnosing the illnesses may be complicated by limited health care infrastructure and because of underlying health issues in some of the population, including malaria and malnutrition.

“I think it’s really important to be aware of what’s happening, and I think it’s also really important not to panic until we have more information,” she said.

“It could be anything," she added. "It could be influenza, it could be Ebola, it could be Marburg, it could be meningitis, it could be measles. At this point, we really just don’t know.”

Dr. Abraar Karan, an infectious disease physician at Stanford Medicine, said the outbreak “does raise alarm bells” because of its location. Interactions between humans and wildlife in Congo increase the risk of a pathogen spilling over from animals, he said, and “many animal infections that transmit from animal to human can cause pretty severe disease.”

To identify the disease, Karan said, local health officials will start by screening for common illnesses like flu or malaria, before testing for less common pathogens. If all those tests are negative, officials may genetically sequence tissue, blood, mucus or bone marrow from infected people, he said.

At the same time, international teams on the ground will collect information about what risk factors sick people have had in common and who they’ve been in contact with, said Amira Albert Roess, a professor of global health and epidemiology at George Mason University.

“I think pretty quickly we’ll start to have an answer as to what this is,” Roess said, noting that there have been “a lot of deaths, especially in such a short amount of time, with the same types of symptoms.”
