Palais briefing notes on cholera in Yemen and circulating vaccine-derived poliovirus in Syria
Suspected cholera cases in Yemen Two years of intense conflict have exacted a heavy toll on the country’s health system, as well as on water and sanitation services, and we’re entering the peak season for the spread of diarrhoeal diseases in Yemen.
Cases of the disease have been confirmed in 19 of the country’s 23 governorates WHO and the United Nations Children’s Fund (UNICEF) are honing in on areas reporting the highest number of cases to stop the disease from spreading further.
The use of the oral cholera vaccine (OCV) is just one of the tools available to combat outbreaks.
Many aspects should be considered before a vaccination campaign: access to the people and places where the cholera is present, logistical constrains (for example availability of cold chain to store the vaccines safely), availability of the vaccines ( we have a worldwide stockpiles of 2 millions cholera vaccines to respond to many outbreak of choldra in different countries).

The detection of the cases demonstrates that disease surveillance systems are functional in Syria.
This outbreak was successfully stopped; the now-detected cVDPV2 strain is unrelated to the WPV1 outbreak.
OPV has been a critical tool in eliminating 99.9% of polio cases worldwide, and while cVDPV is rare, the GPEI is actively working with countries to eradicate both vaccine-derived and wild polio.
