Coronavirus India news: hot and humid? I could be saving India from the worst of the coronavirus | Kolkata News

KOLKATA: India’s climate may have been acting as a shield against Covid-19, which has already claimed more than 2,600 lives in Asia, according to an expert section. But they have not ruled out the possibility of a “silent transmission” of nCoV in the country, which could have disastrous consequences.

Experts have pointed out that, although India has a high population density, and a large part of the Indians do not have access to adequate hygiene practices, ideal factors for the rapid transmission of contagion, viral outbreaks that have wreaked havoc in neighboring countries in recent years. They have not had significant effects in the country.

The good news

Outbreaks of MERS, SARS, Ebola and yellow fever, which caused thousands of deaths in Asia, America and Africa in the last decade, had a minimal impact on India. High temperature and humidity could hinder the survival and potency of viruses, said K K Aggarwal, president of the Heart Care Foundation of India. “Viruses thrive in lower temperatures, so nCoV has spread rapidly to countries in Southeast Asia that are colder and less humid than India. South Korea and Japan have seen a rapid transmission, while India, despite receiving a patient from China in early February, seems to have prevented an outbreak. However, transmission could occur without detection, which could be dangerous, ”said Aggarwal, former president of the Indian Medical Association (IMA).

Particular regions tend to be more vulnerable to certain infections, according to the head of critical care at the International Institute of Cardiac Sciences (RTIICS) RN Tagore, Souren Panja. “Certain regions are prone to viral attacks, and the reasons remain unexplained. But the weather is definitely a deterrent in India. The geographical extension of nCoV suggests that it has so far been restricted to colder climates, ”said Panja.

Internal medicine consultant Arindam Biswas agreed. “The spread of a virus depends on three factors: the agent or the virus itself, the host and the environment. While the virus and the host were present in India, nCoV may not have obtained the ideal climatic conditions to proliferate. Awareness also played an important role in controlling the spread and the government of India has so far done an excellent job to contain the disease, ”he said.

The high incidence of pneumonia in India, especially among the elderly, could be hiding the transmission of nCoV, Aggarwal feared. “All patients with pneumonia should be tested for Covid-19. All patients with acute H1N1 negative pneumonia but who are rapidly advancing should be tested for nCoV. This is also a wonderful opportunity to detect patients with TB in India and eliminate disease, “he said.

Experts also said that an epidemic of the Covid-19 scale is generally fueled by “super propagators” or carriers (infected people), who transmit the disease to a large number of people in the community. It is believed that the outbreak in China was initiated by one of these super spreaders, while the transmission of nCoV on the Diamond Princess ship and in Iran is also attributed to super spreaders. “So far, India seems to have done a commendable job in containing the virus and we have been able to prevent super propagators from unleashing the virus,” Aggarwal said.
