The Virology Unit continued to be the main Public Health Laboratory in the Ministry of Health providing diagnostic services for the prevalent medical viral infection, serving most government hospitals and clinics in the country. It also serves as reference laboratories for diagnosis of wide range of diseases. These include:

  • WHO National Influenza Centre
  • WHO National Laboratory for Poliovirus
  • WHO National Japanese Encephalitis Laboratory
  • National AIDS Reference Laboratory
  • National Laboratory for potency testing of Viral Vaccines viz Measles, Polio live viral vaccines
  • National Reference Laboratory for SARS Corona Virus
  • National Reference Laboratory for Avian Influenza
