With Japanese encephalitis spreading its lethal wings in Assam, the situation becomes dire with every passing minute.
Domestic pigs and wild birds (especially herons) are reservoirs of the virus. Mosquitoes that feed on infected animals can become infected with the virus and then transmit it to humans. This disease is most prevalent in Southeast Asia and East Asia.
Japanese encephalitis has been creating havoc in the state for years. Here's all you need to know about the infection.
Symptoms:
Symptoms in humans include fever, headache, seizures (fits), coma. Although most people with JE virus have no symptoms, the disease can cause long-term problems such as tremors and muscle twitches, personality changes, muscle weakness, paralysis in one or more limbs or death.
Prevention:
Immunisation:
Safe and effective JE vaccines are available to prevent the disease. JE vaccine is recommended for people who are traveling to endemic areas to reduce the risk of the virus and other mosquito-borne infectious diseases. WHO recommends that JE vaccination be integrated into national immunisation schedules in all areas where JE disease is recognised as a public health issue.
Treatment:
Treatment methods include rest, fluids, pain relievers, and medication to relieve the symptoms and overcome the infection.
Other facts:
The incubation period of JEV (time from infection until illness) is typically 5-15 days, but 1 in 250 infections develop into encephalitis. According to CDC, among patients who develop encephalitis, 20% – 30% die. Although some symptoms improve after the acute illness, 30%-50% of survivors continue to have neurologic, cognitive, or psychiatric symptoms.
