West Nile Virus is a disease transmitted by the mosquito on human beings and animals. The Culex mosquitoes transmit the virus following an infection of infected birds. Birds are natural carriers, before humans are infected. Uncommon infection occurs via blood transfusion, organ transplants or mother to child. The danger is increased in hot climates during the summer season. Cities and suburbs with standing water enhance the activity of mosquitoes and the chances of infection in the surrounding communities.
Which Mosquito Species Spreads West Nile Virus?
The following are the three ways in which mosquito species spreads west nile virus:
- Culex pipiens: The most prevalent West Nile Virus carrier in the US. This is a mosquito found in the northern part of the country that bites in the evening and at night, inhabits close to homes and breeds in stagnant water.
- Culex quinquefasciatus: Common in the warm southern states. This mosquito species of the south breeds in dirty water, drains, and sewers, transmitting West Nile Virus in large cities with heavy populations.
- Culex tarsalis: The main West Nile Virus reservoir is in the west. The mosquito likes rural areas, farms and wetlands and they feed on birds and sometimes transmit the virus to humans.
What Are the Symptoms of West Nile Virus?
The following are the three points that are the symptoms of west nile virus:
- Mild Symptoms: Fever, headache, fatigue, body aches, skin rash and swollen lymph nodes occur. These are symptoms that are similar to mild flu and most often have an impact on daily life.
- Severe Symptoms: Fever of high degree, a rigid neck, and confusion, tremor, weakness, seizures, or paralysis occur. These symptoms are the symptoms of neuroinvasive infection of the brain and nervous system.
- Symptom Onset: The symptoms are noticed two to fourteen days after a bite by the infected mosquito. It depends on age, health and the strength of the immune system.
Who Is at Risk for West Nile Virus?
West Nile Virus has impacts in anybody exposed to infected mosquitoes. The risk is higher for individuals working or living outside. The elderly over sixty-five have an increased risk of serious disease. People who have low immunity are also at a higher risk. The individuals who spend too much time outside in the evening or nighttime have higher exposure. Knowledge on individual risk assists families to take precaution against protection and minimise contact with mosquitoes around homes and outdoor settings.
How Can You Prevent West Nile Virus?
The following are the five points in which you can prevent west nile virus:
- Eliminate Mosquito Breeding Sites: Clear stagnant water in containers, gutters and puddles around houses to reduce the possibility of breeding and infection of mosquitoes.
- Use Protective Clothing: Wear long sleeves, long trousers, and light colored clothes to cover more of the body when the mosquitoes are active.
- Apply EPA-Approved Mosquito Repellents: Apply repellents that have DEET, picaridin, or oil of lemon eucalyptus on the uncovered parts of the skin.
- Install Screens and Bed Nets: Install window screens and bed nets against indoor contact with mosquitos particularly at night.
- Professional Mosquito Control: Apply larvicides and adult mosquitoes in regions that have high activity of the West Nile Virus.
When Should You Seek Medical Attention?
Consult a doctor as soon as high fever, severe headache, confusion, and neurological disorders develop after a bite from a mosquito. Blood tests verify West Nile Virus infection and assist physicians in treating the symptoms. Early diagnosis helps to minimize the risk of complications and helps to recover faster. Severe cases of neuroinvasion necessitate hospitalisation to monitor, provide supportive care and treatment. Early treatment is needed to facilitate infection control and forestall the deterioration of the neurological damage. Patients with sudden weakness, tremors or seizures require professional attention immediately.
If you’re seeing mosquitos, schedule a same-day inspection now!
How to Reduce Risk in Your Community
Train neighbors on how to eliminate standing water in containers, gutters and lawns to lessen mosquito breeding within the community. Report any unusual population of mosquitoes or dead birds to the local authorities for monitoring. Local authorities organize the pest control with the usage of larvicides or a fog in the high-risk zones. The involvement of the community in the awareness and surveillance is a preventive measure against the transmission of West Nile Virus. Constant surveillance of mosquitoes and immediate intervention at breeding points safeguards all people. Community/social activities minimize infection risks and preserve health in communities.
