2016 Angola and DR Congo yellow fever outbreak a 32-year-old male Chinese citizen who had been in Angola had developed yellow fever on return. The case was the first imported yellow fever case in China in history. Yellow fever has never appeared in Asia even though the mosquito vector is present. Additional cases were later reported in people who first had symptoms while in Luanda. ProMED-mail moderator Jack Woodall warned that "spread could make the Ebola and Zika epidemics look like picnics in the park!" and that "international action should start now." Chinese authorities strengthened thermal imaging at airports to detect passengers with elevated body temperatures. A Chinese
Yellow fever ribavirin is an effective early treatment of many pathological features of the disease. Ribavirin treatment during the first five days after virus infection improved survival rates, reduced tissue damage in the liver and spleen, prevented hepatocellular steatosis, and normalised levels of alanine aminotransferase, a liver damage marker. The mechanism of action of ribavirin in reducing liver pathology in yellow fever virus infection may be similar to its activity in treatment of hepatitis C, a related virus. Because ribavirin had failed to improve survival in a virulent rhesus model of yellow fever infection, it had been previously discounted as a possible
