What can a person do to reduce the risk of becoming infected with
the West Nile virus?
The following recommendations can help reduce the risk of becoming
infected with the virus:
Stay indoors at dawn, dusk, and in the early evening.
Wear long-sleeved shirts and long pants whenever you are
outdoors.
Apply insect repellent sparingly to exposed skin. An effective
repellent contains 20%-30% DEET (N,N-diethyl-meta-toluamide). DEET
in high concentrations (greater than 30%) may cause side effects,
particularly in
children. Avoid products containing more than 30% DEET.
Repellents may irritate the eyes and mouth, so avoid applying
repellent to the hands of children. Insect repellents should not be
applied to very young children (under 3 years of age).
Spray clothing with repellents containing permethrin or DEET
since mosquitoes may bite through thin clothing.
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.
Take preventive measures in and around your home. Repair or install door and window screens, use air conditioning, and reduce breeding sites (eliminate standing water).
If you find a dead bird, the CDC recommends you not handle the carcass with bare hands. Contact your local health department for instructions for the notification procedure and disposing of the carcass. They may tell you to dispose of the bird after they log your report.
Note: Vitamin B and "ultrasonic" devices are not effective in
preventing mosquito bites.

The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly. They can sometimes be tender, painful or disfiguring. The treatment of swollen lymph nodes depends upon the cause.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
Tremor is the involuntary movements of one or more parts of the body. Causes of tremor include neurological disorders, neurodegenerative diseases, drugs, mercury poisoning, overactive thyroid and liver failure. There are several types of tremor. Treatment depends upon the type of tremor and availability of medications for the condition.
Encephalitis is a brain inflammation that causes sudden fever, vomiting, headache, light sensitivity, stiff neck and back, drowsiness, and irritability. Meningitis is an infection that causes inflammation of the meninges that surround the brain and spinal cord. Symptoms of meningitis include high fever, headache, nausea, vomiting, and stiff neck.
Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
Insomnia is the perception or complaint of inadequate or poor-quality sleep because of difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Secondary insomnia is the most common type of insomnia. Treatment for insomnia include lifestyle changes, cognitive behavioral therapy, and medication.
Ticks are known transmitters of disease to humans and animals. Tick-borne diseases include Lyme disease, Rocky Mountain spotted fever, Q fever, tularemia, babesiosis, and Southern tick-associated rash illness. Infected ticks spread disease once they've bitten a host, allowing the pathogens in their saliva and mouth get into the host's skin and blood. Tick bites are typically painless, but the site of the bite may later itch, burn, turn red, and feel painful. Individuals allergic to tick bites may develop a rash, swelling, shortness of breath, numbness, or paralysis. Tick bite treatment involves cleaning and applying antibiotic cream.
Bug bites and stings have been known to transmit insect-borne illnesses such as West Nile virus, Rocky Mountain spotted fever, and Lyme disease. Though most reactions to insect bites and stings are mild, some reactions may be life-threatening. Preventing bug bites and stings with insect repellant, wearing the proper protective attire, and not wearing heavily scented perfumes when in grassy, wooded, and brushy areas is key.
