AccuWeather, the US-based forecaster,
quoted Dr John Nicholls, a pathology professor at the University of Hong Kong, saying there are three things coronavirus does not like: sunlight, temperature and humidity.
"Sunlight will cut the virus's ability to grow in half, so the half-life will be 2.5 minutes, and in the dark it's about 13 to 20 [minutes]. Sunlight is really good at killing viruses," Nicholls said.
Deutsche Welle also cited Thomas Pietschmann, a virologist from Germany's Centre for Experimental and Clinical Infection Research, who said the coronavirus is "not very heat-resistant, which means that the virus quickly breaks down when temperatures rise".
Heat and humidity
Meanwhile, Dr Abdul Ghafur, an infectious disease specialist based in the Indian city of Chennai, said compared to its population of 1.3 billion, the dozens of confirmed cases in India "is not a big number".
He said the heat and humidity in the country "could be one of the reasons" why coronavirus is not spreading faster in his country, as the weather limits the virus from travelling "longer or faster".
"It is not just the temperature that is killing in the warm climate, it is the humidity as well. The humidity reduces the transferability of the virus," he told Al Jazeera.
