As of August 9, India has officially announced more than 2.15 million new crown confirmed cases, continuing to rank third in the world after the United States and Brazil. < / P > < p > India reported the first confirmed case at the end of January, and it took 5.5 months to break through 1 million cases on July 17, and it took only 21 days to break through 2 million cases on August 7. Some analysts pointed out that the epidemic situation in India has changed from “mild outbreak” to “exponential growth”. < / P > < p > although some Indian media attributed the recent surge in cases to increased detection efforts, the “three knives” hanging over the head of India’s anti epidemic work should not be ignored. < p > < p > since August, more than 50000 new confirmed cases have been reported in India. Among them, Maharashtra, the most serious state, has more than 10000 new cases in a single day. According to Indian media, one of the reasons for the surge in confirmed cases is that the government has stepped up its testing efforts. Nearly 22.79 million people have been tested in India as of August 6, with 639042 people detected on the same day, according to data released by the Indian Medical Research Council on August 7. < p > < p > since the beginning of August, many politicians have been confirmed to be infected with new coronavirus. Indian interior minister Amit Shah confirmed on social media twitter on the 2nd that he was positive for the virus. According to Indian media reports, Shah also attended a cabinet meeting a few days before the diagnosis, with Indian Prime Minister modi and other cabinet members present. In addition, the chief executives of several Indian states have also confirmed the infection. However, due to the high population density, poor health conditions, low education level of residents and widespread poverty, urban slums have been considered as the difficulty of epidemic prevention and control. < p > < p > a survey released by the city government of Mumbai, India’s largest city, showed that 57% of the subjects in the city’s slum population receiving serological testing carried antibodies to the new coronavirus, while only 16% of those outside the slums carried antibodies to the new coronavirus. In an interview with the times of India and other media, experts of the investigation group said that the results showed that there were a large number of asymptomatic infected people in the slums. < / P > < p > some observers believe that there is a significant gap between the infection rate inside the slums and outside the slums. The slums are like a “barrier lake”. There is still considerable uncertainty about whether the epidemic will be accelerated by the overflow of the “barrier lake” in the future. Thousands of rural to urban migrant workers have lost their jobs since India imposed a national blockade in March. The Indian government cut off the domestic transportation for the sake of epidemic prevention, causing them to be trapped in cities. Many people had no choice but to find ways to return home by truck or on foot, which aggravated the rapid spread of urban epidemic to rural areas. Taking Rajasthan as an example, local health officials said that since May, more than 1.1 million migrant workers have returned home from high incidence cities such as Mumbai and Pune, which has affected 33 rural areas in the state. What’s more, the medical resources and public awareness of epidemic prevention in these areas are far less than those in big cities. In some places, the infected people are even excluded, which aggravates the public’s resistance to detection. In addition, the arrival of rainy season leads to traffic inconvenience and frequent disasters, which makes epidemic prevention and control more difficult. < / P > < p > the epidemic situation in India is spreading rapidly, and it is difficult to alleviate it in a short time. How to choose and balance the epidemic prevention and control and return to work is a big problem for the Indian government. According to a report released by Nomura Securities a few days ago, the epidemic has seriously impacted the demand side and supply side of India. It is estimated that India’s economic growth will shrink by 6.1% in this fiscal year. In addition, India’s unemployment rate also remained high at 10.99% in June. < / P > < p > since May, the Indian government has been forced to gradually release the seal. However, due to the rebound of the epidemic, Bangalore, Pune and other cities, as well as Bihar, Tamil Nadu and other states, were forced to re blockade after being unsealed. Zhang Wenjuan, director of India China Research Center of jindel global university, believes that due to the particularity of India’s development stage and industrial structure, the continuous blockade and anti epidemic has brought some unique pressure on India’s economy. For example, most cases are concentrated in economically developed big cities and the service industry is the pillar industry, but the service industry is most vulnerable to the epidemic. These have made India’s economy more vulnerable under the impact of the epidemic, and limited the space for the Indian government to move in the prevention and control of the epidemic.
