What is West Nile Virus?

16:02 - 6 February , 2024

Disease

It is a viral infection caused by mosquitoes; it can be serious, especially if the virus enters the brain, triggering encephalitis or meningitis.

Babies, older adults, and people with suppressed immune systems are more susceptible to infection, but other factors can increase the risk of contracting this disease, such as:

  • Pregnancy.
  • Breastfeeding.
  • Blood transfusions.
  • Chemotherapy.
  • Organ transplant.

Signs and symptoms West Nile Virus

Symptoms can appear between 3 to 12 days after being infected, with the following signs:

  • Sore abdomen.
  • Migraine.
  • Diarrhea.
  • Lack of appetite.
  • Swollen lymph nodes
  • Sore throat.
  • Muscle pain.
  • Nausea.
  • Rash.
  • High fever.
  • Vomit.

The infection can worsen, presenting the following symptoms:

  • Fatigue.
  • Mental confusion.
  • Weakness of muscles, arms, and legs.
  • Fainting.
  • Neck stiffness.

Diagnosis and treatment West Nile Virus

The doctor will analyze your symptoms and clinical history, perform a physical examination, and request blood tests or spinal tap, MRI, and CT scan to confirm that it is a West Nile virus infection.

As it is a virus, there is no direct treatment for this condition, so recovery depends on the patient’s immune system strength, but the following may be indicated:

  • Abundant fluid intake.
  • Bland diet.
  • Antidiarrheal drugs.
  • Painkillers.
  • Medications to inhibit nausea.
