INTRODUCTION:
West Nile contagion( WNV) is a mosquito- borne disease that can cause mild to severe symptoms in humans and creatures.
It's set up in numerous countries around the world, especially in Africa, Europe, the Middle East, Asia, and North America.
Travelers who visit these regions may be exposed to WNV through the bite of an infected mosquito.
In this blog post, we will explain what WNV is, how it affects the body, how to prevent and treat it, and what to do if you suspect you have it.
What's West Nile contagion?
WNV is a type of contagion that belongs to the same family as Zika contagion, dengue contagion, and yellow fever contagion.
Mosquitoes become infected when they feed on infected catcalls and then they can transmit the contagion to other catcalls, creatures, or humans when they bite them.
How Does West Nile Contagion Affect The Body?
WNV can cause different types of illness depending on the person's immune system and the strain of the contagion.
According to the CDC about 80 of people who are infected with WNV don't develop any symptoms. About 20 of people who are infected develop mild symptoms, similar as fever, headache, tiredness, nausea, puking, muscle aches, and rash.
These symptoms generally last for a few days or weeks and are often mistaken for the flu .
This form of WNV infection is called West Nile fever.
About 1 out of 150 people who are infected develop severe symptoms, similar as high fever, stiff neck, confusion, coma, tremors, seizures, muscle weakness, vision loss, numbness, or palsy.
These symptoms may last for several weeks or months and may cause permanent neurological damage or death.
This form of WNV infection is called West Nile Neuroinvasive Disease( WNND), which includes meningitis( inflammation of the filling of the brain and spinal cord), encephalitis( inflammation of the brain), or acute limp palsy( a condition that causes sudden weakness or palsy of one or more branches).
WNV can also affect creatures, especially horses.
Horses are more susceptible to WNV than humans and can develop severe neurological symptoms analogous to those seen in humans .
There are vaccines available for horses to prevent WNV infection but there are no vaccines or specific treatments for humans yet.
How Can West Nile Contagion be Prevented?
The best way to prevent WNV infection is to avoid mosquito bites. Mosquitoes that carry WNV are utmost active from dusk to dawn , so it's important to limit out-of-door activities during these hours or wear protective apparel and use insect repellent.
Insect repellents that contain DEET(- diethyl- m- toluamide), picaridin( KBR 3023), IR3535( ethyl butylacetylaminopropionate) or oil painting of lemon eucalyptus( p- menthane -3,8-diol) are effective against mosquitoes.
Follow the instructions on the label carefully and apply repellent only on exposed skin or apparel. Don't spot repellent on cuts, injuries, or irritated skin.
Don't spot repellent directly on your face; spot it on your hands first and then irk it on your face. Avoid getting repellent in your eyes or mouth.
Wash your hands after applying repellent and wash off repellent with cleaner and water when you return indoors.
Another way to prevent WNV infection is to reduce mosquito breeding sites around your home and community. Mosquitoes lay their eggs in standing water, so it's important to eliminate any sources of stagnant water where mosquitoes can breed .
Some examples are:
1 -Empty and clean birdbaths and pet water coliseums at least once a week.
2 - Dispose of any containers that can hold water, similar as barrels, bottles, tires, buckets, or pots.
3 - Drill holes in the bottom of recycling containers or trash barrels to prevent water accumulation.
4 - Clear clogged gutters and drains to allow water to inflow freely.
5 - Change the water in out-of-door cradles or pools regularly.
6 - Cover rain barrels or cisterns with tight- befitting lids or screens.
7 - Repair any leaks in out-of-door faucets or pipes.
You can also help prevent WNV infection by reporting dead catcalls to your original health department or wildlife agency.
Don't touch or handle dead catcalls with your bare hands use gloves or a shovel to dispose of them.
How is West Nile Contagion Diagnosed and Treated?
If you develop symptoms of WNV infection.
Your Dr will ask you about your symptoms, medical history, and possible exposure to mosquitoes or infected creatures.
Your Dr may also order blood tests or spinal fluid tests to confirm the opinion of WNV infection.
There is no specific treatment for WNV infection;
the treatment is substantially supportive and depends on the severity of the symptoms.
Mild symptoms can be treated with over- the- counter pain relievers, fever reducers, and fluids.
Severe symptoms may require hospitalization, intravenous fluids, respiratory support, and medications to reduce swelling in the brain or prevent seizures .
The prognostic for WNV infection varies depending on the person's age, health status, and immune system. utmost people who develop mild symptoms recover completely within a few weeks.
Some people who develop severe symptoms may have long- term complications, similar as memory loss, cognitive impairment, muscle weakness, or depression.
The mortality rate for WNND is about 10, and it's higher among older grown-ups and people with underlying medical conditions.
Conclusion
West Nile contagion is a serious disease that can affect anyone who's exposed to infected mosquitoes.
It can cause mild to severe symptoms, and in some cases it can be fatal.
The best way to prevent WNV infection is to avoid mosquito bites and eliminate mosquito breedingsites. However seek medical attention as soon as possible.
If you develop symptoms of WNV infection. There is no vaccine or specific treatment for WNV infection, but supportive care can help reduce the threat of complications and improve the outcome.
