The increase in Africa's serious yellow fever outbreak appears to have slowed but it remains a serious public health event, the World Health Organization says. "Despite the considerable progress made, the Committee concluded that the outbreak remains a serious public health event which warrants continued national action and international support. Furthermore, the imminent onset of the rainy season will intensify vector activity, thus raising subregional risks of yellow fever transmission," WHO said in a release. WHO said the global stockpile of yellow fever vaccine stands at 6 million doses. There is no specific antiviral drug to treat yellow fever infections.
