While the declining trend in new plague case reports and reduction in hospitalizations due to plague is encouraging, WHO expects more cases of plague to be reported from Madagascar until the typical plague season ends in April 2018. Sustaining ongoing operations, including active case finding and treatment, comprehensive contact identification, follow-up and antibiotic treatment, rodent and flea control, and safe and dignified burials is crucial during the outbreak and through the plague season as it is critical to minimize bubonic plague infections and human-to-human transmission of pneumonic plague.Based on available information and response measures implemented to date, WHO estimates the risk of potential further spread of the plague outbreak at national level remains high.

Current risk assessmentThe risk assessment is in the process of being reviewed based on the evolving situation. While the current outbreak began with one large epidemiologically linked cluster, cases of pneumonic plague without apparent epidemiologic links have since been detected in regions across Madagascar, including the densely populated cities of Antananarivo in the central highlands and Toamasina on the east coast of Madagascar. Due to the increased risk of further spread and the severe nature of the disease, the overall risk at the national level is considered very high.
The Ebola epidemic in West Africa may have surprised most of the medical establishment – this is the first such outbreak in the region – but the risk had been steadily rising for at least a decade. The risk had grown so high, in fact, that this outbreak was almost inevitable and very possibly predictable.All that was needed was to see the danger was a bat’s eye view of the region. Once blanketed with forests, West Africa has been skinned alive over the last decade. Guinea’s rainforests have been reduced by 80%, while Liberia has sold logging rights to over half its forests. Within the next few years Sierra Leone is on track to be completely deforested.This matters because those forests were habitat for fruit bats, Ebola’s reservoir host. With their homes cut down around them, the bats are concentrating into the remnants of their once-abundant habitat. At the same time, mining has become big business in the region, employing thousands of workers who regularly travel into bat territory to get to the mines.
We’ve a new update from the Madagascar MOH on their ongoing plague outbreak – that while dated the 13th – is a summary of activity through the 12th. The trajectory of the outbreak continues to be concerning, with 561 cases now reported across 35 districts Remarkably, of those, 415 (74%) are pneumonic plague, which is normally a relatively rare presentation which spreads as a respiratory illness. Updates from the MOH are in French, and are often presented in formats that make machine translation difficult, but we can piece together the gist from the following PDF file.
On 23 August 2017, a 31-year-old male from Tamatave, visiting Ankazobe District in central highlands, developed malaria-like symptoms. On 27 August, he developed respiratory symptoms during his journey in a shared public taxi from Ankazobe District to Tamatave (via Antananarivo). His condition worsened and he died. His body was prepared for a funeral at the nearest hospital, Moramanga District Hospital, without safety procedures. Additionally, 31 people who came into contact with this case either through direct contact with the primary case or had other epidemiological links, became ill, and four cases of them died.The outbreak was detected on 11 September, following the death of a 47-year-old woman from Antananarivo, who was admitted to a hospital with respiratory failure caused by pneumonic plague. The public health authorities Direction de la Veille Sanitaire et de la Surveillance Epidémiologique (DVSSE) immediately launched field investigations.As of 28 September 2017, a total of 51 cases (suspected, probable and confirmed) of pneumonic plague, including 12 deaths were reported in the country. The diagnosis was confirmed by the Institut Pasteur de Madagascar by polymerase chain reaction test and using rapid diagnostic test.In addition to the 51 suspected, probable and confirmed cases of pneumonic plague, and during the same period another 53 cases of bubonic plague including seven deaths have been reported throughout the country. One case of septicaemic plague has also been identified and they were not directly linked to the outbreak.
