India in stage 2 of COVID-19 transmission, a look at four stages of virus spread  

The number of coronavirus cases in India has risen to 166 with 15 new confirmed cases on Thursday, which includes three deaths, two in Delhi and one in Karnataka.

India is fighting the coronavirus bravely and government’s efforts in containing the spread of the deadly COVID-19 have been appreciated by global agencies, including the World Health Organisation (WHO).

However, the country is passing through the most crucial phase of the transmission of the disease. According to the Indian Council of Medical Research (ICMR), the country is in the second stage of transmissions, i.e. local transmission. He also said that there is no sign of community transmission which is the third stage, even as the ICMR called upon private labs for testing.

However, the case of a 20-year-old man from Delhi testing positive in Chennai has raised concerns of community transmission of the disease as he has no travel history from overseas, except Delhi.

Let’s first understand the different stages of the spread of the virus:

Stage 1 | Imported Cases: These are those who have travelled to virus-hit foreign countries and have come back to India.

Stage 2 | Local Transmission: These are those cases who have come in contact with patients who have a travel history.

Stage 3 | Community Transmission: Community transmission is when a patient not exposed to any infected person or one who has travelled to any of the affected countries tests positive. Large areas get affected when community transmission takes place.

Stage 4 | Epidemic: This is the last and the worst stage where the disease take the shape of an epidemic with no clear end point like it did in China.

The number of coronavirus cases in India has risen to 166 with 15 new confirmed cases on Thursday, which includes three deaths, two in Delhi and one in Karnataka.

The government on Tuesday banned the entry of passengers from Afghanistan, Philippines and Malaysia to India with immediate effect.

This instruction is a temporary measure and shall be in force till March 31 and will be reviewed subsequently.

With coronavirus cases swelling in the country, the government has also banned the entry of passengers from the European Union countries, Turkey and the UK from March 18 till March 31.

On March 11, India suspended all visas, except a few categories such as diplomatic and employment, till April 15 to prevent the spread of coronavirus.

The government has also proposed certain social distancing measures as a preventive strategy for implementation, a health ministry official said said, adding that these interventions are proposed to be in force till March 31.

The key measures proposed include closure of all educational institutions -- schools, colleges and universities -- gyms, museums, cultural and social centres, swimming pools and theatres, he said.
