West Nile virus
As of 28 July, the National Reference Centre for Exotic Diseases (CESME) in Italy reported that five pools of mosquitoes were positive for West Nile virus in Sardinia, Lombardy and Emilia Romagna.
During the June to November transmission season, West Nile fever cases in humans are shown in ECDC’s weekly updated West Nile fever maps. This informs blood safety authorities of West Nile fever (WNF)-affected areas and enables them to identify significant changes in the epidemiology of the disease.
Zika virus infection
On 1 August, the Florida Department of Health in the United States confirmed four autochthonous Zika virus cases infected by local mosquitoes in Miami-Dade and Broward counties. As of 4 August, the Florida Department of Health (DOH) had identified, in total, 15 locally acquired Zika cases in Florida who likely acquired the infection through a mosquito bite. The DOH believes that active transmission of the Zika virus is still only occurring in one small area of Miami-Dade County. Among the 15 cases, six are asymptomatic and were identified as a result of the door-to-door community survey that the DOH is conducting.
The US CDC has issued travel advice for people who live in or travelled to Wynwood in Miami any time after 15 June. Pregnant women have been advised not to travel to this neighbourhood.
In addition, the US CDC has published an official health advisory on guidance for 'Travel and Testing of Pregnant Women and Women of Reproductive Age for Zika Virus Infection Related to the Investigation for Local Mosquito-borne Zika Virus Transmission in Miami-Dade and Broward Counties, Florida'. The CDC is also recommending Zika testing for all pregnant women in the continental United States at prenatal visits in their first and second trimesters.
On 3 August, the Ministry of Health in Cuba reported two cases of locally acquired Zika in the city of Hoguin.
In Vietnam, the Ministry of Health reported one case of locally acquired Zika virus in Phu Yen Province.
Since 1 February 2016, Zika virus infection and the related clusters of microcephaly cases and other neurological disorders constitute a public health emergency of international concern (PHEIC). Since 2015, and as of 4 August 2016, WHO has reported 65 countries and territories with mosquito-borne transmission.
ECDC publishes an epidemiological update every Friday together with maps with information on countries or territories which have reported confirmed autochthonous cases of Zika virus infection. A Zika virus infection Atlasis also available.
