It has already been found in mosquitoes in Seville.
mosquitoes with virus that causes West Nile fever (WNV)have already been discovered in the Seville municipalities of La Puebla del Rio and Villamanrique de la Condesa, meaning earliest date in Andalusia since infectious agent surveillance was conducted in these dipterans.
According to the Department of Health’s first weekly Culex mosquito surveillance report, carried out through traps from June 3 to 9The virus was detected in several shipments of mosquitoes captured in Dehesa de Abajo, Puebla del Rio and Villamanrique de la Condesa.
Two traps that they caught mosquitoes with positivity They are located in rural areas, more than 1.5 kilometers from the city, the department said.
However, the Council has notified the municipalities involved of this situation in order to may strengthen surveillance, control and communication measures citizens identified in the Municipal Vector Surveillance and Control Plan (PMVCV).
The population of mosquitoes carrying West Nile virus is increasing
Andalusia has an Integrated Vector Surveillance and Control Program for West Nile Virus, instructions for its development and an updated risk map showing the different risk levels in all Andalusian municipalities.
Documents adapted to reality Andalusia and incorporating experience and knowledge acquired in recent years.
Prevent its circulation
The Board recalled that the local administration and health administration, based on the situation in the municipality of one level or another, must implement a number of public health measures aimed at preventing the circulation of the virus and, as a result, interrupt possible transmission to humans. These actions are enhanced when the presence of a circulating virus is detected, as in this case.
The discovery of positive results reinforces the need for adequate mosquito surveillance that can detect viral circulation as early as possible to prevent possible spread of the disease to the population.
Observational traps are used to record the density of potentially disease-carrying mosquitoes and, as in this case, subsequent analysis checks whether they are infected with WNV.
They discovered the presence of the Nile virus in animals and in several cities in Andalusia.
The Ministry of Health has 26 own traps located in the municipalities of Cadiz, Cordoba, Malaga and Seville.and provides detailed information on catches and positives detected each week during the mosquito season.
WNV is a disease that persists in nature through a cycle of transmission from birds and mosquitoes. Infected mosquitoes can bite people and transmit the disease (as in horses), although the person then does not transmit the disease to others. it is also unable to infect a “healthy” mosquito and act as a vector.
In many cases, trap placement is done in rural areas outside of populated areas to be able to test for virus circulation or high mosquito densities in rural areas before a mosquito problem occurs. , urban environment.
