West Nile Virus Up until the 1990s, the West Nile virus was virtually unheard of. The disease existed, but it was limited to the small West Nile District of Uganda, and was considered only a minor risk to humans. That has changed drastically over the past several years, with the virus spreading literally around the world. The first U.S. case of West Nile was reported in New York City in 1999, and the virus quickly spread throughout the country. In 2012 alone, there were 5,387 confirmed cases of West Nile in the U.S., resulting in 243 deaths. People who survive the illness are often left with long-term damage to the nervous system, resulting in tremors, seizures, or the loss of memory and motor skills. West Nile Symptoms If someone becomes sick with the West Nile virus, it is important that they seek medical treatment as quickly as possible. The West Nile virus can cause multiple different diseases, which means the symptoms can be wide-ranging. Symptoms which may indicate a West Nile infection include: • Fever • Headache • Body aches • Neck stiffness • Skin rash • Sore throat • Nausea • Vomiting • Chills • Confusion • Fatigue • Muscle weakness • Numbness • Paralysis Roughly 80 percent of all people infected with the West Nile virus show no symptoms at all. The only negative impact of such symptomless infections is that they can possibly spread the virus to others. How West Nile is Spread The West Nile virus cannot be spread through touch or other types of casual contact. For an infection to occur, the virus must come into contact with a person’s blood. Though there have been a few cases of the West Nile virus spreading through blood transfusions or organ transplants, the vast majority of infections are caused by mosquito bites. Mosquitoes become carriers of the virus after feeding on infected blood. Once infected, they can spread the virus to any other people or animals that they feed on. The West Nile virus is not limited to humans, and can infect pets, livestock, and wildlife. In fact, most cases of West Nile result from mosquitoes feeding on infected birds; mosquitoes are not likely to become carriers of the virus after biting infected humans or other animals. Preventing West Nile Infections Since the West Nile virus is spread by mosquitoes, you can avoid catching the disease by controlling the mosquito population and protecting yourself from mosquito bites. Mosquitoes need a body of water to reproduce, so eliminating standing water is one way to reduce their numbers. You can also use safe pesticides, such as the organic PCO Choice, to kill outdoor mosquitoes. Since you cannot eliminate all mosquitoes, it is very important to use an insect repellant when going outdoors during mosquito season. BEST YET Organic bug spray is highly effective at repelling mosquitoes, without using any harmful chemicals. You can also use TickShield, which is a stronger, longer-lasting version of the same all-natural repellant.

Koji su simptomi groznice Zapadnog Nila Ubojiti virus stigao je i u Hrvatsku, za sada tek na životinje, no kako ga prenose tigrasti komarci, sigurno će stići i do ljudi Virus Zapadnog Nila, trenutno najspominjaniji virus na svijetu stigao je u i Hrvatsku gdje je pronađen kod životinja, no vjerojatno neće trebati dugo čekati da prijeđe na ljude. Virus inače prenose tigrasti komarci, dobro poznati po svojim opakim ugrizima. U SAD je situacija puno ozbiljnija i ima već skoro 1600 zaraženih, a čak 65 ljudi je umrlo. Inače se groznica Zapadnog Nila javlja u zemljama s visokim temperaturama tijekom proljeća i jeseni, primjerice u Tunisu, Turskoj i Egiptu. Virus Zapadnog Nila se širi ugrizom azijskog tigrastog komarca i nije prenosiv s čovjeka na čovjeka, a prvi simptomi su primjetni tri do 14 dana nakon uboda. Simptomi groznice Zapadnog Nila Groznica se manifestira u samo dva od deset slučajeva zaraze, a problem je u prepoznavanju simptoma kod zaraženih jer su vrlo slični prehladi i gripi. Najčešći je simptom povišena tjelesna temperatura praćena umorom, glavoboljom i boli u zglobovima. U nekim slučajevima virus izaziva osip na koži, bol u očima i natečene limfne čvorove. U samo jedan posto slučajeva može izazvati tešku neurološku infekciju čija je posljedica upala moždane ovojnice - meningitis i encefalitis, a nekad se proširi i na kralježnicu, što se manifestira teškim disanjem i iznenadnom slabošću u nogama i rukama. Tešku infekciju prepoznat ćete po povišenoj temperaturi, ukočenosti vrata, dezorijentaciji, lošoj koordinaciji, boli i iznenadnoj paralizi, drhtanju i snažnim glavoboljama. Ukoliko primjetite neke od tih simptoma posjetite liječnika. Od komaraca se zaštitite uobičajenim sredstvima poput mreža na prozorima, preparatima protiv uboda, odjećom dugih rukava i redovnim mijenjanjem vode kućnim ljubimcima. Kante ispod oluka i u vrtu obavezno praznite nakon kiše.
