Holtville-(UC) - As feared, the West Nile virus (WNV) has arrived in California, having been found in mosquitoes and possibly chickens in the Imperial Valley and Coachela. Transmitted by infected mosquitoes, primarily affects some wild birds and horses. First identified in Uganda in 1937, remains effective remedy.
Have been reported isolated and sporadic cases of infection with this virus in humans is estimated that less than 1 percent of the population will develop severe symptoms requiring hospitalization.
"Most horses and humans who develop the disease no symptoms," says John N. Guerrero, agricultural consultant and dairy cattle. "In people who develop the disease, symptoms may include fever, nausea, headache, hives or rash," said the specialist.
West Nile virus was first extended by the African continent. Appeared in the U.S. in 1999 in the northeast and has spread steadily westward through the normal migration of birds and birds. It is expected to reach California this year. In 2002, there were more than 4,000 cases in the country.
"Great One of the scourges of humanity, the mosquito is the main vector between birds and humans," says Guerrero. To transmit the disease, a mosquito must first bite an infected bird. The virus migrates to the mosquito salivary glands, which, by biting an animal or person, it injects saliva infecting the victim.
The main carriers of this virus are wild birds, especially crows, jays and magpies, but horses are also vulnerable. As in humans, most victims do not develop the disease equine, only 25 percent have symptoms, which include ataxia, stumbling, incoordination, limb weakness, muscle spasms and paralysis. Of horses with symptoms, 20 to 40 percent die.
"It is important to take precautionary measures when there is a chance that mosquitoes bite and infect animals," says Guerrero. Horse owners can get a vaccine to prevent WNV in horses through veterinarians enrolled. "Once a horse is infected, there is no treatment for this virus. Therefore it is important to get vaccinated before they can chop and infect mosquitoes, "says Guerrero.
In people who develop infection with West Nile virus can go from 5 to 15 days after the mosquito bite until they have symptoms. Mild infections usually last from 3 to 6 days. The elderly and immunocompromised persons are at increased risk of illness. Children are particularly vulnerable.
There being no cure for West Nile virus, an emerging disease, preventive measures to prevent transmission of WNV through the bite of mosquitoes are of utmost importance. Guerrero recommends the following guidelines:
Check your property to ensure you do not have standing water in old tires, empty pots, buckets, cans, wheelbarrows, etc.. Mosquitoes can breed in water that stays accumulated over four days.
Frequently clean sources or birdbaths and water bowls for pets and pets. Clean out roof gutters, remove leaves and debris that may obstruct the proper drainage of rainwater.
Keep swimming pools clean and properly chlorinated. Make sure no standing water on the pool deck. If you have a small pool for their children, place it upside down when not in use so that water does not accumulate there. Do the same with wheelbarrows when not in use.
Pierce the bottom of containers that are outdoors, to avoid having stagnant water.
Reduce exposure to mosquito bites. The specialist advises trying to avoid outdoor activities at dawn and dusk when the level of mosquito activity is greatest. If you will be outdoors, wear a mosquito repellent containing DEET and pants and long sleeved shirt. When using an insect repellent, be sure to follow manufacturer's instructions to the letter.
Guerrero suggests a revision of the "chicken wire" or screens on doors and windows to ensure they do not have holes where mosquitoes can enter. You can also consider the use of external screens and tents for shade near where there are horses and around homes to protect animal and human West Nile virus.
And finally, if you find a dead bird, do not touch it with your hands. Contact the Department of Health Services, toll free 1-877-968-2473 to report dead bird.
