West Nile Virus Information

West Nile Information
What Is West Nile Virus?

West Nile virus (WNV) is a potentially serious illness. Discovered all the way back in 1937 in Africa, the West Nile virus probably didn't make its way to the United States until 1999. But since then, it has been a cause of concern all over the country during the summer months. Experts believe WNV is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall. This fact sheet contains important information that can help you recognize and prevent West Nile virus.

What Can I Do to Prevent WNV?

• The easiest and best way to avoid WNV is to prevent mosquito bites.

• When you are outdoors, use insect repellents containing DEET (N, N-diethyl-meta-toluamide). Follow the directions on the package.

• Many mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times or consider staying indoors during these hours. Light-colored clothing can help you see mosquitoes that land on you.

• Make sure you have good screens on your windows and doors to keep mosquitoes out.

• Use mosquito netting or bed canopy netting where needed, especially if you travel to areas that have limited mosquito control.

• Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children's wading pools empty and on their sides when they aren't being used.

What Are the Symptoms of WNV?

WNV affects the central nervous system. Symptoms vary. • Serious Symptoms in a Few People. About one in 150 people infected with WNV will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent.

• Milder Symptoms in Some People. Up to 20 percent of the people who become infected will display symptoms which can include fever, headache, and body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. Symptoms can last for as short as a few days, though even healthy people have been sick for several weeks.

• No Symptoms in Most People. Approximately 80 percent of people (about 4 out of 5) who are infected with WNV will not show any symptoms at all.

How Does West Nile Virus Spread?

• Infected Mosquitoes. Most often, WNV is spread by the bite of an infected mosquito. Mosquitoes are WNV carriers that become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.

• Transfusions, Transplants, and Mother-to-Child. In a very small number of cases, WNV also has been spread through blood transfusions, organ transplants, breastfeeding and even during pregnancy from mother to baby.

• Not through touching. WNV is not spread through casual contact such as touching or kissing a person with the virus.

How Soon Do Infected People Get Sick?

People typically develop symptoms between 3 and 14 days after they are bitten by the infected mosquito.

How Is WNV Infection Treated?

There is no specific treatment for WNV infection. In cases with milder symptoms, people experience symptoms such as fever and aches that pass on their own. In more severe cases, people usually need to go to the hospital where they can receive supportive treatment including intravenous fluids, help with breathing and nursing care.

What Should I Do if I Think I Have WNV?

Milder WNV illness improves on its own and people do not necessarily need to seek medical attention for this infection though they may choose to do so. If you develop symptoms of severe WNV illness, such as unusually severe headaches or confusion, seek medical attention immediately. Severe WNV illness usually requires hospitalization. Pregnant women and nursing mothers are encouraged to talk to their doctor if they develop symptoms that could be WNV.

What Is the Risk of Getting Sick from WNV?

People over 50 at higher risk to get sick. People over the age of 50 are more likely to develop serious symptoms of WNV if they do get sick and should take special care to avoid mosquito bites.

Being outside means you're at risk. The more time you're outdoors, the more time you could be bitten by an infected mosquito. Pay attention to avoiding mosquito bites if you spend a lot of time outside, either working or playing.

Risk through medical procedures is very low. All donated blood is checked for WNV before being used. The risk of getting WNV through blood transfusions and organ transplants is very small, and should not prevent people who need surgery from having it. If you have concerns, talk to your doctor.

Pregnancy and nursing do not increase risk of becoming infected with WNV. The risk that WNV may present to a fetus or an infant infected through breast milk is still being evaluated. Talk with your care provider is you have concerns.

What Else Should I Know?

If you find a dead bird: Don't handle the body with your bare hands. Contact your local health department for instructions on reporting and disposing of the body.

Here are preventive measures that you and your family can take: Protect yourself from mosquito bites: • Apply insect repellent sparingly to exposed skin. The more DEET a repellent contains the longer time it can protect you from mosquito bites. A higher percentage of DEET in a repellent does not mean that your protection is better—just that it will last longer. DEET concentrations higher than 50% do not increase the length of protection. Choose a repellent that provides protection for the amount of time you will be exposed outdoors. Repellents may irritate the eyes and mouth, so avoid applying repellent to the hands of children. Whenever you use an insecticide or insect repellent, be sure to read and follow the manufacturer's DIRECTIONS FOR USE, as printed on the product. • Spray clothing with repellents containing permethrin or DEET since mosquitoes may bite through thin clothing. Do not apply repellents containing permethrin directly to exposed skin. If you spray your clothing, there is no need to spray repellent containing DEET on the skin under your clothing. • Use mosquito or bed netting when needed, especially if in the woods. • When possible, wear long-sleeved shirts and long pants whenever you are outdoors. • Place mosquito netting over infant carriers when you are outdoors with infants. • Consider staying indoors at dawn, dusk, and in the early evening, which are peak mosquito biting times. • Install or repair window and door screens so that mosquitoes cannot get indoors. Help reduce the number of mosquitoes in areas outdoors where you work or play, by draining sources of standing water. In this way, you reduce the number of places mosquitoes can lay their eggs and breed. • At least once or twice a week, empty water from flower pots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans. • Check for clogged rain gutters and clean them out. • Remove discarded tires, and other items that could collect water. • Be sure to check for containers or trash in places that may be hard to see, such as under bushes or under your home. Note: Vitamin B and "ultrasonic" devices are NOT effective in preventing mosquito bites.

The most popular and perhaps most versatile pop up room is the Frikon Beach 6’ x 6’ Shade. This model is easy to set up, take down and very functional almost anywhere. When folded down, it fits into a pizza shaped carry bag which measures 31” in diameter, making storage and carry extremely easy. Once folded down into the bag, the Beach Shade can be transported almost anywhere and stowed just as easily. The Beach Shade has a “D” shaped zipper door, with a zipper handle on both sides of the door making entrance and exit easy.

The 6’ x 6’ is the best selling of the screen room, as its size when set up makes it fit just about wherever it is needed. Some of the larger rooms cannot fit certain spaces and the larger rooms are more difficult to fold up. One thing is the 6’ x 6’ Beach Shade is all screen, with the exception of the top which offers shade, but the sides do not. It has no flooring. Thus this is ideal for the beach or deck, or anywhere all sides need to be open and complete visibility a must. The only downside is that some people need more space than 6’ x 6’.

The Frikon Hexagonal Screen Room measures 12’ x 12’ at the cross and has three of its six sides shaded. This makes it more of a complete room, while offering more privacy to the user. It is also more aerodynamic, making it a better screen room for the beach, as wind is more likely to blow over the top as opposed to catching a side. The Frikon Hex room has no flooring and has a ceiling of 6’. The ropes and stakes that come with each Hex Room give the room the stability it needs. This is a favorite of the RV crowd as well as athletic teams that use the Hex room to set up a base when they are playing. Thus it becomes a base camp, changing/locker room, etc. It is also large enough to fit a good sized table and 6-8 chairs inside. Once folded up, this has a diameter of 33” and weighs 12 lbs.

The largest of the screen rooms is the 8’ x 8’. The major difference with this item as opposed to the others, besides the size, is that it has a floor and more difficult to fold down. Set-up is still a snap, but there is more work to folding this item then the other, smaller sizes. It has the same “D” shaped zipper door, and still offers the same in mosquito protection. Folded up this is about 34” in diameter and weighs about 15 lbs. While people try to use this at the beach, the ideal spot for this item is the back yard. It really is too big for the beach and unnecessary. The 6’x 6’ or Hex will do just fine and there is no need for this anywhere other than the back yard.
