Signs and symptoms if you have Nipah virus.
Human infections range from asymptomatic infection to acute respiratory infection (mild, severe), and fatal encephalitis.
Infected people initially develop symptoms including fever, headaches, myalgia (muscle pain), vomiting and sore throat. This can be followed by dizziness, drowsiness, altered consciousness, and neurological signs that indicate acute encephalitis. Some people can also experience atypical pneumonia and severe respiratory problems, including acute respiratory distress. Encephalitis and seizures occur in severe cases, progressing to coma within 24 to 48 hours.
Nipah virus (NiV) is an emerging zoonotic virus (a virus transmitted to humans from animals).
