Chicken and turkeys infected with WNV may show no signs of infection. Because WNV causes inflammation of the brain, expect clinical signs of the virus to be nervous system problems. Abnormal head posture, a wobbly gait, inability to stand, staggering and tremors are common symptoms.
What are 3 signs of West Nile virus?
These are the most common symptoms of West Nile fever:
- Fever.
- Headache.
- Body aches.
- Skin rash on trunk of body.

- Fever, headache, and sore throat.
- Lack of appetite.
- Muscle aches.
- Nausea, vomiting, and diarrhea.
- Rash.

How soon do symptoms of West Nile virus appear?
Usually, symptoms occur from 3 to 14 days after being bitten by an infected mosquito. There is no specific treatment for viral infections, other than to treat the symptoms and provide supportive care.
How long does it take for West Nile virus to go away?

Can birds recover from West Nile virus?
Do birds infected with West Nile virus die or become ill? Although some infected birds, especially crows and jays, frequently die of infection, most birds survive.
Does West Nile go away on its own?
Mild signs and symptoms of a West Nile virus infection generally go away on their own. But severe signs and symptoms — such as a severe headache, fever, disorientation or sudden weakness — need immediate attention. Exposure to mosquitoes where West Nile virus exists increases your risk of getting infected.
How do you get rid of West Nile virus?
There is no specific treatment for West Nile virus (WNV) disease; clinical management is supportive. Patients with severe meningeal symptoms often require pain control for headaches and antiemetic therapy and rehydration for associated nausea and vomiting.
How do you diagnose West Nile virus?
Laboratory diagnosis is generally accomplished by testing of serum or cerebrospinal fluid (CSF) to detect WNV-specific IgM antibodies. Immunoassays for WNV-specific IgM are available commercially and through state public health laboratories.
Is West Nile virus fatal?
About 1 out of 150 infected people develop a serious, sometimes fatal, illness. You can reduce your risk of WNV by using insect repellent and wearing long-sleeved shirts and long pants to prevent mosquito bites.
What are the odds of getting West Nile virus?
Even if the mosquito is infected, less than 1% of people who get bitten and become infected will get severely ill. The chances you will become severely ill from any one mosquito bite are extremely small.
What are the long term effects of West Nile virus?
West Nile virus (WNV) is a mosquito-borne virus that can cause severe neurological disease in those infected. Those surviving infection often present with long-lasting neurological changes that can severely impede their lives. The most common reported symptoms are depression, memory loss, and motor dysfunction.
What part of the body does West Nile virus affect?
In one out of 150 cases, West Nile virus is a more serious problem. It can cause a dangerous infection that affects the brain and nervous system. This infection can cause lasting or permanent side effects, such as muscle weakness. Some people die.
How do animals get West Nile virus?
How do dogs or cats become infected with West Nile virus? The same way people become infected by infected mosquitoes bites. The virus is maintained in the mosquito’s salivary glands. During blood feeding, the virus is injected into the animal.
Does West Nile stay in your body forever?
Like many other viruses, medical tests indicate that once a person has been infected with West Nile, he/she develops a natural immunity to future infection by the virus for life. However, this immunity may decrease over time or with further health conditions that compromise the immune system.
Can dogs get West Nile virus?
Dogs and cats can be infected with West Nile Virus through the bite of a mosquito, so minimizing their exposure to mosquitoes is recommended.
How do I know if my bird has West Nile?
Clinical Signs
Birds with West Nile virus often show neurological signs including loss of coordination, head tilt, tremors, weakness, apparent blindness, and lethargy. Most infected crows and jays will die within 3 weeks.
How does West Nile affect birds?
The disease is spread by mosquitoes, and can affect not only birds but humans as well, usually causing flu-like symptoms. Birds with visible symptoms of West Nile virus often die within a few days. Affected birds will often be fluffed out and stay low to the ground, or seem off balance and unable to stand.
Can chickens get West Nile virus?
Although chickens and turkeys can become infected when experimentally inoculated with the virus or bitten by infected mosquitoes, these birds do not develop the clinical disease. Their immune system quickly responds to infection by producing antibodies that clear the virus from their body.
How can the West Nile virus be prevented in animals?
The best way to avoid WNV is to prevent mosquito bites. Keep horses indoors during peak mosquito activity times (dusk and dawn). Remove potential mosquito breeding sites (e.g., standing water). Avoid or minimize lights inside stables during the evening or overnight.
Is West Nile contagious person to person?
Transmission. West Nile virus is rarely transmitted from one human to another but rather is spread through the following: Infected Mosquitoes Generally, WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds.
