MADAGASCAR WARNS OF PLAQUE OUTBREAK: The Ministry of Health in Madagascar has warned of an outbreak of an “annual” plague in 16 districts of seven regions, including two cases in the capital, Antananarivo. Plague is a bacterial disease caused by Yersinia pestis, which primarily affects wild rodents. It is spread from one rodent to another by fleas. Humans bitten by an infected flea usually develop a bubonic form of plague, which produces the characteristic plague bubo – a swelling of the lymph node. If the bacteria reach the lungs, the patient develops pneumonia (pneumonic plague) which is then transmissible from person to person through infected droplets spread by coughing. If diagnosed early, bubonic plague can be successfully treated with antibiotics. Pneumonic plague, on the other hand, is one of the most deadly infectious diseases; patients can die 24 hours after infection. The mortality rate depends on how soon treatment is started, but is always very high. According to the World Health Organization, plague in Madagascar tends to be seasonal and occurs mainly during the rainy season with around 500 cases reported annually. Since August there have been 119 identified cases and 40 deaths. WHO does not recommend any travel or trade restriction based on the current information available.
