WHO completed a massive cholera vaccination campaign in Nigeria

Vastavam web: The World Health Organization said today it has completed a massive cholera vaccination campaign in restive northeastern Nigeria, where the disease has already killed 54 people.The week-long campaign allowed 844,000 people to receive one dose of the vaccine, which offers protection against the deadly disease for six months, WHO spokesman Tarik Jasarevic told reporters in Geneva.
Northeastern Nigeria is in the grip of a humanitarian crisis caused by the Boko Haram insurgency, which has killed at least 20,000 people and displaced more than 2.6 million.With 54 related deaths so far, the case fatality rate, which measures the severity of an epidemic by defining the proportion of fatal cases within a specific timeframe, is currently at 1.4 percent — well above the emergency threshold of one percent.
The first cholera case was identified in Borno State on August 16 and has since spread, mainly in camps for those displaced by the Boko Haram insurgency.Two doses of the vaccine are needed to offer full protection, but in emergency situations, the WHO allows for a single dose to be given to speed up the coverage.In addition to the vaccination campaign, WHO and other aid organisations are helping the Nigerian government to respond to the outbreak by establishing cholera treatment centres, “increasing outreach to communities with information on cholera and on prevention”, Jasarevic said.About 8.5 million people in Nigeria’s northeast, out of 17 million in the wider Lake Chad region encompassing Nigeria, Cameroon, Chad and Niger, need humanitarian assistance, according to the United Nations.
