In the Democratic Republic of Congo (DRC) since October 24, more than 400 people have been infected with an unidentified virus of which more than 30 could not survive. This is reported by the World Health Organization (WHO). According to the organization, 406 cases of the unknown disease were reported in the Panzi health zone (Kwango province) from October 24 to December 5. The main symptoms include fever, headache, runny nose, cough and body aches. In severe cases, there is significant emaciation. Children, predominantly under the age of five, account for the largest number of cases. Access to the remote rural area of Panzi is difficult due to the ongoing rainy season, and the journey from Kinshasa, the capital of DRC, takes about 48 hours. WHO officials said these difficulties, as well as limited diagnostic capabilities in the country, are delaying the determination of the underlying cause of the disease. At present, rapid response medical teams in Panzi are collecting biomaterial samples for laboratory tests, studying the dynamics of disease transmission and providing assistance to the sick. WHO experts emphasized that given the clinical manifestations and symptoms, acute pneumonia, influenza, COVID-19, measles and malaria could be potential causes of the disease, with malnutrition playing a contributing role.
