West Nile Virus
The Cities of Grand Forks and East Grand Forks have scheduled a citywide spraying for mosquitoes for Tuesday night between 8 p.m. and 1 a.m. West Nile virus has been identified in the Grand Forks region. The cities of Grand Forks and East Grand Forks urge citizens to take extra precautions to avoid being bitten by mosquitoes. The person infected with West Nile is over the age of 65.
“West Nile virus is an infection most commonly spread through mosquito bites,” State epidemiologist Dr. Joshua Clayton said in a news release. “The rate of severe infection that includes swelling of the brain and spinal cord with symptoms of stiff neck, confusion, and muscle weakness is highest in South Dakota and other Midwest states. Raising awareness of human cases can ensure residents and visitors alike take action to reduce their risk,” Clayton said
West Nile virus is a mosquito-borne illness that can cause febrile illness (fever) or more severe neurological disease. Here are some key points about it:
- Symptoms:
- Most people (about 8 out of 10) infected with West Nile virus do not develop any symptoms.
- Febrile illness (fever) occurs in about 1 in 5 infected individuals, with symptoms like headache, body aches, joint pains, vomiting, diarrhea, or rash.
- Severe symptoms affecting the central nervous system (such as encephalitis or meningitis) occur in about 1 in 150 people. These symptoms include high fever, neck stiffness, stupor, disorientation, tremors, muscle weakness, vision loss, and paralysis.
- Recovery from severe illness may take weeks or months, and some effects can be permanent.
- People over 60 years old and those with certain medical conditions are at greater risk for severe illness.
- Diagnosis:
- Healthcare providers diagnose West Nile virus based on signs, symptoms, and possible exposure to infected mosquitoes.
- Laboratory testing of blood or spinal fluid helps confirm the diagnosis.
- Treatment:
- There is no specific medicine for West Nile virus. Antibiotics do not treat viruses.
- Rest, fluids, and over-the-counter pain medications can relieve symptoms.
- Severe cases may require hospitalization for supportive treatment.
- Prevention:
- Prevent mosquito bites by using repellents, wearing protective clothing, and eliminating standing water where mosquitoes breed.
Most people infected with West Nile virus recover completely, but vigilance and preventive measures are essential. If you have concerns, consult your healthcare provider and Stay safe.
Symptoms of West Nile Virus
West Nile virus can result in febrile illness or more severe neurological disease. Here are the key symptoms:
- No Symptoms (Most People):
- About 8 out of 10 infected individuals do not develop any symptoms.
- Febrile Illness (Fever):
- Approximately 1 in 5 people infected experience fever along with headache, body aches, joint pains, vomiting, diarrhea, or rash.
- Most recover fully, but fatigue and weakness may persist for weeks or months.
- Severe Symptoms (Few People):
- Roughly 1 in 150 infected individuals develop severe illness affecting the central nervous system (encephalitis or meningitis).
- Symptoms include high fever, neck stiffness, stupor, disorientation, tremors, muscle weakness, vision loss, and paralysis.
- Severe illness can occur at any age, but those over 60 or with certain medical conditions are at greater risk.
- Recovery from severe illness may take weeks or months, and some effects can be permanent.
- About 1 in 10 with severe symptoms die.
Risk Factors for West Nile Virus
Risk factors for severe illness from West Nile virus include:
- Age: People over 60 years old are at higher risk of severe symptoms.
- Health Conditions: Individuals with certain medical conditions (such as cancer, diabetes, or high blood pressure) may be more susceptible.
- Weakened Immune System: People with weakened immune systems (due to medications or other factors) are at increased risk.
- Pregnancy: Pregnant women can experience more severe symptoms if infected.
- Time of Exposure: Exposure during peak mosquito activity (usually summer and early fall) increases the risk.
How Protect from West Nile Virus?
- Use Insect Repellent: Apply an EPA-registered insect repellent on exposed skin, avoiding areas near the eyes and mouth.
- Wear Protective Clothing: Opt for long-sleeved shirts and pants to reduce mosquito exposure.
- Avoid High-Risk Times: Stay indoors during peak mosquito activity, especially early mornings and around sunset.
there is not a vaccine for West Nile, so prevention is key.
