HOW DOES IT SPREAD?

It can spread by droplet / contact / airborne source.

  • The most common mode of transmission is through the respiratory droplets (coughing and sneezing)
  • Transmission can occur when people touch an object contaminated with virus and touch their eyes / nose / mouth
  • Transmission is also possible by aerosol contact with conjunctiva and spread through secretions of the eye as well. Thus people with conjunctivitis and respiratory symptoms in addition to recent international travel should be more cautious.

CLINICAL MANIFESTATIONS

Patients can be carriers of infection before experiencing any of the symptoms

Symptoms usually show up 2-14 days after exposure to the virus

Virus can cause conjunctivitis:

  • Have more of warm fluids and warm foods
  • Stay well hydrated
  • Do not touch your face, eyes, nose or mouth when your hands are dirty.
