2020 was undoubtedly a year we will never forget. Beyond pandemic outbreaks, other diseases that were considered to be eradicated or endemic in some countries outside our borders have since been removed. For example, he West Nile virus Killed eight people in Andalusia in 2020. that same year alone, 71 people suffered from meningoencephalitis Due to the virus spread by this mosquito, 56 of them were from the province of Seville, 15 from Cadiz, and a probable case were reported in Malaga. Since then, this alert has remained dormant, with some very specific cases. Now the danger seems to have increased. The National Association of Environmental Health Companies (ANECPLA) has asked “to be very cautious” “triggered” growth the number of mosquitoes that spread West Nile virus, ‘Culex’ (genera ‘Pipiens’ and ‘Very Little’).
The population of this genus of mosquitoes has increased especially in recent weeks in the Sevilleian words of La Puebla del Rio, Korea and Palomeres. ) It is recommended that the competent administration and citizens of the area remain vigilant to avoid a new outbreak that spread two years ago.
It is important to remember that There is no person-to-person transmission of West Nile virus fever, but it is produced only by the bite of the Culex mosquito. For this reason, preventive measures are especially important. they focus avoid cuttingUsing all necessary measures, such as installing mosquito nets on windows and doors, as well as, as far as possible, Avoid walking in wetland areas at dusk and dawn use it long sleeves and repellent if required.
Similarly, this year, institutions again emphasize the importance of being alert to this menace and recall the importance of involving citizens in this containment exercise. “We cannot, in any case, isolate citizens, as it is up to them to put in place such important preventive regulations. cleaning mosquito breeding sitesDomestic and peridomestic, that is, those that live in stagnant water, pools, tanks or any outdoor container that can store water. ”, they indicate.
summer, the most dangerous time
The virus is believed to have entered Europe Infected migratory birds in Africa sub-Saharan however, the spread is now afor public health concerns, For this reason, they recall that “it cannot be ruled out that it may have been transmitted to other regions, especially now in the summer, the peak of reproduction of the transmitting vector.”
en general, hot weather due in the spring and summer months Climate change making conditions more favorable for the virus and its mosquito carriers, accelerating the growth and spread of mosquitoes breeding seasonWhich in turn can increase their numbers.
along with hot winters Infected females are producing common domestic mosquitoes (culex pipiens) survive the winter in regions that were previously very cold (such as northern Italy); Therefore, the virus can survive now if the mosquitoes survive the winter and spread at the beginning of the year.
