According to an analytical study conducted by the Indian Institute of Technology (IIT), Mandi, travelers from Dubai and the UK were the primary sources of COVID-19 imports into India.
According to the research, which has been published in the Journal of Travel Medicine, COVID-19 was primarily driven by Indian travel in Indian states.
The study also found that infected cases from Tamil Nadu, Delhi and Andhra Pradesh played a lesser role in spreading the disease outside their communities. While infected people in Gujarat, Rajasthan, Maharashtra, Kerala, Jammu and Kashmir and Karnataka played a significant role in local broadcasting and some of them also carried out inter-state transfers.
“We tracked the spread of COVID-19 and its spread from a global to national level and identified some super spreaders that play a central role in the transmission of the disease in India. Phase 1 was using COVID-19 spread. The travel history of the patients, and it was found that most of the broadcasts were local, ”Sarita Azad, Assistant Professor, IIT Mandi, told PTI.
“The research team used the travel history of infected patients from January to April as the primary data source and a social network depicting the spread at an early stage of the epidemic. The research found that the maximum number of connections were established Were. Dubai (144) and UK (64), “she said.
Ms Azad pointed out that the statistical matrix calculated from the data showed that Dubai and the UK played an important role in spreading the disease to Indian states and COVID-19 was the primary source of imports in India.
“Dubai’s eigenvector centrality was the highest that made it the most influential node. Statistical metrics calculated from the data revealed that Dubai and the UK played a significant role in disease spread in Indian states and COVID-19 was the primary source of imports. India .
“On the basis of modularity class, separate groups were formed in the Indian states, demonstrating the formation of a multi-layered social network structure. States such as Tamil Nadu, Delhi and Andhra Pradesh reported significant increases in confirmed cases. The first phase of nationwide lockout, which extended from 25 March to 14 April, ”she said.

So, it is likely that cases infected with these states played a lesser role in spreading the disease outside their communities. While states like Gujarat, Rajasthan. They said that Maharashtra , Kerala, Jammu and Kashmir and Karnataka have played an important role in local broadcasting, and some of them have also done interstate transfers.
Ms. Azad, who did analytical studies with her student Sushma Devi, said, “When an epidemic subsists like COVID-19, 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 spread nationally globally from 30 January to 6 April. It is an important contribution to understanding the transmission of the disease in India during the initial phase of the epidemic. Will happen. “
According to the Union Ministry of Health, India’s COVID-19 caseload had nearly 60 lakh infections with 88,600 fresh infections occurring on Sunday, while the number of people suffering from the disease crossed 49 lakhs and the national recovery rate was 82.46 percent.
