As India's Coronavirus Cases Spike, Worries Rise Anjana Pasricha NEW DELHI - For weeks India, the world's second most populous country, stayed alert but hopeful that it was escaping the worst of the coronavirus outbreak -- only three cases had been detected in a southern state among students who returned from China. That optimism was shattered when the number of cases jumped this week to 29 including 16 Italian tourists. The spurt in cases has prompted authorities to announce extra precautions. Primary schools in the capital New Delhi have been shut till the end of the month. Screening will be stepped up at airports to cover all passengers arriving in the country instead of those from 12 countries listed earlier. " The government has initiated measures to contain the virus," Health Minister Harsh Vardhan told parliament on Thursday saying that there is no need to panic. The potential for rapid spread of the virus in India given the country's dense population has been a focus of serious concern for health experts. Intensive efforts are on to identify and isolate the hundreds of people who came in touch with those who are infected with the virus including the Italian tourists who travelled widely in the northern state of Rajasthan. "With the increasing global spread of the disease, we are confronted with new challenges. The contact tracing of positive cases requires the tracing of hundreds of contacts in multiple locations and monitoring their health," Vardhan told reporters earlier. Agra, home to the famous Taj Mahal, was among the places put on alert after six cases were identified from the city. A summit of India and the European Union scheduled to be held on March 20 in Brussels has also been postponed in view of the coronavirus outbreak. "Health authorities of both the countries suggested that travelling must not take place at present," Foreign Ministry spokesman Raveesh Kumar said. India, a key supplier of generic drugs to the world, this week also announced restrictions on export of some common medicines raising fears of creating shortages in other countries. They include the widely-used pain reliever paracetamol, certain antibiotics and vitamins. .
