Скачать или смотреть Immunisation begins in Philippine polio outbreak

(20 Sep 2019) Philippine health officials declared a polio outbreak in the country on Thursday, nearly two decades after the World Health Organisation declared it to be free of the highly contagious and potentially deadly disease.
Health Secretary Francisco Duque III said at a news conference Friday in Manila that authorities have confirmed at least one case of polio in a 3-year-old girl in southern Lanao del Sur province and detected the polio virus in Manila's sewage and waterways in the southern Davao region.
Those findings are enough to declare an outbreak of the crippling disease in a previously polio-free country like the Philippines, he said.
The World Health Organization and the United Nations Children's Fund expressed deep concern over polio's reemergence in the country and said they would support the government in immunising children, who are the most susceptible, and strengthening surveillance.
The weakened virus used in vaccines replicates for a short time in children's intestines and is excreted in their feces. In rare instances, they said, the weakened virus can strengthen in areas with poor sanitation and hygiene.
Children who have not been properly immunised can be susceptible.
They said the last known case from a wild strain of the virus in the Philippines was in 1993. Wild poliovirus type 2 was declared globally eradicated in 2015.
There is no known cure for polio, which can only be prevented with vaccines.
