A prestigious scientific panel told the White House on Tuesday that it does not look like coronavirus will go away once the weather warms up.

US President Donald Trump has claimed that “when it gets a little warmer (the virus) miraculously goes away.”

In their letter to the White House, members of a National Academy of Sciences committee said data is mixed on whether coronavirus spreads as easily in warm weather as it does in cold weather, but that it might not matter much given that so few people in the world are immune to coronavirus.

“There is some evidence to suggest that (coronavirus) may transmit less efficiently in environments with higher ambient temperature and humidity; however, given the lack of host immunity globally, this reduction in transmission efficiency may not lead to a significant reduction in disease spread without the concomitant adoption of major public health interventions,” the letter stated.

The letter noted, for example, that a study of the outbreak in China showed that even under maximum temperature and humidity conditions, the virus spread “exponentially,” with every infected person spreading it to nearly two other people on average.

The scientists sent the letter to Kelvin Droegemeier at the White House Office of Science and Technology Policy.

The letter from the NAS scientists notes that some laboratory studies have shown reduced transmission of the virus under warmer and more humid conditions, but that it's still a concern.

The letter points out that in the real world, the virus is still transmitting in countries with warm weather.

“Given that countries currently in ‘summer’ climates, such as Australia and Iran, are experiencing rapid virus spread, a decrease in cases with increases in humidity and temperature elsewhere should not be assumed,” the letter said.
