India has learned lessons from past health epidemics- the plague Gujarat 1994, avian flu H5N1 in 2005-2006 Maharashtra, Madhya Pradesh, swine flu H1N1 Pune, and more recently MERS. The Indian Express looks at past epidemics, how they were tackled and what India learned from them. Major improvements in sanitation and hygiene since then and advances in medicine, public health. 

Experience was gained. The municipal commissioner of Thane near Mumbai was district collector of Jalgaon during the avian flu epidemic. He used quarantine to restrict transmission of infected material. He shifted bus stands, closed weekly markets, and had health workers check symptoms in a 3 kilometre radius area. His message for today- have a contingency plan, track, test and treat people, stay focused, not panic, and know exactly what has to be done.

Moving migrant crisis today was also seen in Surat, 1994, with the plague epidemic when migrant workers left the city. The government had to use paramilitary units in 1994 to quarantine the entire area.

During these earlier epidemics the Indian Council of Medical Research and other medical organizations played a significant role. One of the lessons learned from the H1N1 epidemic that originated in Mexico was the need for effective surveillance and real time reporting so that the pathogen can be recognized in real time and tests done at labs to determine what it is, followed by effective response through isolation of region and patients. Dr. Pradeep Awate, Maharashtra's surveillance officer, says robust surveillance systems are important to understand the magnitude of the problem and strategically place resources.

The strategies put in place for the Nipah virus in Kerala state by its Health Department in 2019 are the same ones now being used for cornonavirus - contact tracing and management of persons under quarantine.
