- COVID-19 got induced in India mainly due to international travels
- Tamil Nadu, Delhi and Andhra Pradesh played less role in spreading the disease
- The study is an important contribution to understand the disease transmission in India
According to an analytical study done by the Indian Institute of Technology (IIT) Mandi, travellers from Dubai and the UK were the primary source of coronavirus spreading in India, PTI reported.
The research, that is published in the Journal of Travel Medicine, states that COVID-19 got induced in Indian states mainly due to international travels.
"We tracked the spread of COVID-19 and its diffusion from the global to the national level and identified a few superspreaders who played a central role in the transmission of the disease in India. The COVID-19 spread in phase one was traced using the travelling history of the patients, and it was found that most of the transmissions were local," Sarita Azad, Assistant Professor, IIT Mandi, told PTI.

"The research team has used the travel history of infected patients from January to April as the primary data source and a social network was created depicting the spread in the early phase of the pandemic. The research found that the maximum numbers of connections were established from Dubai (144) and the UK (64),” Azad added.
The study also shows that infected cases from Tamil Nadu, Delhi and Andhra Pradesh did not spread the deadly disease outside their communities as much as the cases from Gujarat, Rajasthan, Maharashtra, Kerala, Jammu and Kashmir, and Karnataka did.

Azad, who conducted the analytical study, along with her student Sushma Devi, said, "When a pandemic like COVID-19 subsides, a good research work serves as a record for the future. In this work, we have used real-time data and demonstrated how the disease got diffused from the global to the national level from January 30 to April 6."
"This will be an important contribution to understand the disease transmission in India during the early phase of the pandemic," she told PTI.
India has registered over 5.9 million coronavirus cases and more than 94 thousand deaths so far.
