The detection of cVDPV2s underscores the importance of maintaining high routine vaccination coverage everywhere to minimize the risk and consequences of any poliovirus circulation. This risk is magnified by known population movements between the affected area of Democratic Republic of the Congo, Uganda, Central African Republic and South Sudan, and the upcoming rainy season which is associated with increased intensity of virus transmission. Public Health Rapid Support Team. Surveillance and immunization activities are being strengthened in neighbouring countries. Whether experts will be able to find infected bats during the latest DRC outbreak remains unknown, partly because there may have been undetected cases of the disease dating back months; any culprit bat colony may have moved on by now. The onset date of paralysis was 26 April During the massive Ebola crisis that gripped west Africa from to , researchers were told about a bat-filled roosting tree in Guinea they suspected may have been ground zero for that outbreak.
Most outbreaks have originated in Africa or from lab accidents elsewhere, and have remained small—but people traveling from sites of a outbreak that roiled west Africa led to isolated cases in locations including the U. Share via Print Ebola experts suspect that fruit bats are the primary reservoir for the disease. So far, no new cases have been detected in , and there is no evidence that this virus has spread further geographically. The onset date of paralysis was 26 April WHO assessed the overall public health risk at the national level to be very high and the risk of international spread to be high due to the proximity of the recent detection of the AFP case in Ituri which is close to an international border and with known population movement. She is based in Washington, D. Rounding up some of those bats could have given scientists a chance to test the animals and confirm them as a main reservoir for the disease. Last year eight cases were reported, and half of the infected people died. It can be transmitted via sexual contact. Those realities are expected to severely hinder the response to this outbreak. This risk is magnified by known population movements between the affected area of Democratic Republic of the Congo, Uganda, Central African Republic and South Sudan, and the upcoming rainy season which is associated with increased intensity of virus transmission. Countries, territories and areas should also maintain uniformly high routine immunization coverage at the district level to minimize the consequences of any new virus introduction. WHO will continue to evaluate the epidemiological situation and outbreak response measures being implemented. The vast central African country has dealt with more outbreaks of this often-fatal hemorrhagic disease than any other nation. The affected area of the country, located along its borders with Rwanda and Uganda, is also the site of frequent cross-border movement and a prolonged humanitarian crisis. The remaining operational gaps in the outbreak response must be urgently addressed. The geographic extent of the outbreak response to all three strains is now being re-evaluated, given the confirmed spread of one of the strains to Ituri and confirmation of the new strain in Mongala. The DRC has more robust Ebola surveillance and lab testing capacity in place, he says, and that may be a factor. But the tree burned down and the bats were reduced to char, destroying the opportunity to search for much evidence—although researchers were able to use trace DNA fragments to pinpoint that they were Mops condylurus, an insect-eating species common across central and west Africa. To comply with the Temporary Recommendations issued under the PHEIC, any country infected by poliovirus should declare the outbreak as a national public health emergency and consider vaccination of all international travelers. Surveillance and immunization activities are being strengthened in neighbouring countries. Whether experts will be able to find infected bats during the latest DRC outbreak remains unknown, partly because there may have been undetected cases of the disease dating back months; any culprit bat colony may have moved on by now. Countries affected by poliovirus transmission are subject to Temporary Recommendations. That makes me think this is the tip of the iceberg. Centers for Disease Control and Prevention who has responded to most known Ebola outbreaks. When news broke this week that the Democratic Republic of the Congo is facing yet another Ebola outbreak, many public health experts were not surprised. Circulation of the strain was confirmed when the same strain was isolated in stool specimens from two healthy community contacts.
