Outbreak and Current Disease Status Information

Enterovirus D68 in the United States of America

WHO Disease Outbreaks news - Tue, 09/16/2014 - 20:15
On 10 September 2014, the United States of America informed the Pan American Health Organization/World Health Organization (PAHO/WHO) about an outbreak of severe respiratory illness associated with Enterovirus D68 (EV-D68). As of 16 September 2014, 130 laboratory-confirmed cases of EV-D68 have been reported in 12 US states – Alabama, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Missouri, New York, Oklahoma, and Pennsylvania. Investigations into suspected clusters in many other states are ongoing.

EV-D68 is identified using molecular techniques at a limited number of laboratories in the USA. Enterovirus infections, including EV-D68, are not nationally notifiable, but laboratory detections of enterovirus and parechovirus types are reported voluntarily to the National Enterovirus Surveillance System, which is managed by the US Centers for Disease Control and Prevention.

Ebola virus disease – Democratic Republic of Congo

WHO Disease Outbreaks news - Tue, 09/09/2014 - 20:45
Between 2 and 9 September 2014, there have been 31 more cases of Ebola virus disease (EVD) reported in the Democratic Republic of the Congo (DRC), increasing the cumulative number of cases to 62 (14 confirmed, 26 probable, and 22 suspect). In total, 35 deaths have been reported (9 confirmed and 26 probable). No deaths have been reported among suspected cases. Nine health-care workers have been diagnosed with EVD, including 7 deaths. All the cases have been localized in Jeera county. The affected villages are Watsi Kengo, Lokolia, Boende, and Boende Muke. Currently, 9 cases have been hospitalized: 4 in Lokolia; 2 in Watsikengo; 2 in Boende; and 1 in Boende Moke. A total of 386 contacts have been listed and 239 contacts have been followed-up. All cases and contacts are linked to the initial index case reported to the World Health Organization on 26 August 2014.

During a regional meeting between the Ministry of Health of DRC and the Southern African Development Community on the management and prevention of EVD transmission, the following measures were recommended: standardization of the interventions for the prevention of EVD and enhancement of sanitary border control without impeding international traffic.

Poliovirus in Cameroon – update

WHO Disease Outbreaks news - Sat, 09/06/2014 - 06:00
In Cameroon, 2 new wild poliovirus type 1 (WPV1) cases were reported from the East Region, with onset of paralysis on 26 June 2014 and 9 July 2014. Genetic sequencing of these latest isolated viruses confirms continued wild poliovirus circulation, gaps in surveillance resulting in undetected transmission and geographic expansion to new areas of the country.

The outbreak in Cameroon has been ongoing since at least October 2013. The outbreak continued into 2014, with international spread to Equatorial Guinea. In March 2014, WHO elevated the risk assessment of international spread of polio from Cameroon to very high, due to expanding circulation and influx of vulnerable refugee populations from Central African Republic (CAR). This risk assessment remains in place. Further undetected circulation in Cameroon cannot be ruled out. Moreover, the risk of virus spreading into CAR is considered to be particularly high given the large-scale population movements from CAR into Cameroon.
