RESUMEN
La Fiebre del Nilo Occidental (FNO) es producida por un arbovirus (familia Flaviviridae, género flavivirus) y transmitida por mosquitos Culex. En los '50 se detectó en Israel, Egipto e India, y en 1974 en Sudáfrica. Luego en Argelia (1994), Rumania (1996), República Checa (1997), Rusia (1999) y en EE.UU. (1999), notificados al CDC desde entonces, 24.716 casos con 983 fallecidos. En el 2012 lleva afectando a 3.545 personas con 147 fallecidos. En la Unión Europea (23/8/2012) se notificaron 91 casos (37 confirmados). En Grecia los casos han ascendido a 86. En países vecinos a la UE se notificaron 143 casos. El virus se ha diseminado a Canadá, América Central y el Caribe, afectando las Islas Caimán, Jamaica, República Dominicana, México, Puerto Rico y Cuba. Argentina, sin antecedentes hasta marzo de 2006, confirmó en Córdoba la infección en un hombre y otros 3 en el Chaco. En abril de ese año se confirmó la muerte de 2 caballos en SA de Areco (Buenos Aires), 1 en Entre Ríos y en el 2010 otro equino en Córdoba. Las aves infectadas por hembras de Culex migran a Centroamérica y América del Sur, transmitiendo el virus a especies de vertebrados (mascotas; animales de granja -caballos- y el hombre). El virus puede infectar a otros seres humanos por transfusiones, trasplantes de órganos, etc. No se transmite de persona a persona. Clínicamente se presenta con un cuadro febril o con compromiso neurológico. Los factores de riesgo son variados (HIV/SIDA, trasplante de órganos, quimioterapia, embarazo, etc). La prevención es la lucha contra el mosquito. La fumigación es un recurso útil. Las aguas estancadas donde se reproducen los mosquitos deben drenarse. Los cambios climáticos ocasionan importantes consecuencias para la salud humana con multiplicación de vectores infectantes. Los EE.UU. han tenido este año un invierno suave y un verano caluroso...
ABSTRACT
The FNO is caused by an arbovirus (family Flaviviridae, genus Flavivirus) and transmitted by Culex mosquitoes. In the 50 was detected in Israel, Egypt and India and in South Africa in 1974. Then in Algeria (1994), Romania (1996), Czech Republic (1997), Russia (1999) and the USA (1999), reported to the CDC since then, 24,716 cases with 983 deaths. In 2012 carries affecting 3.545 people with 147 deaths. In the European Union (23/08/2012) 91 cases were reported (37 confirmed). In Greece’s case amounted to 86. In neighboring countries the UE 143 cases were reported. The virus has spread to Canada, Central America and Caribbean, affecting the Cayman Islands, Jamaica, Dominican Republic, Mexico, Puerto Rico and Cuba. Argentina shows no background until March 2006, confirmed in Cordoba infection in a man and another three in Chaco. In April of that year confirmed the death of two horses in San Antonio de Areco (Buenos Aires), one in Entre Ríos and in 2010 another horse in Cordoba. Birds infected Culex females migrate to Central and South America, transmitting the virus to vertebrate species (pets, farm animals, horses, and man). The virus can infect humans for transfusions, organ transplants, etc. It is not transmitted from person to person. Clinically presents with a fever or neurological compromise. Risk factors are varied (HIV / AIDS, organ transplants, chemotherapy, pregnancy, etc). Prevention is the fight against the mosquito. Fumigation is a useful resource. The stagnant water where mosquitoes breed, should be drained. Climate changes cause significant consequences to human health, with infective vector multiplication. The US has had this year a mild winter and a hot summer. Mankind will become aware of the damage that involves not observe regulatory mitigation measures and environmental pollution. Only a commitment to protecting the environment is everyone’s future hope. We will address other emerging pathology related to climate change...
