(CNN) — A prestigious scientific panel told the White House Tuesday that it does not appear that the coronavirus disappears once the weather gets warm. President Donald Trump has claimed that “when it heats up a bit [el virus] disappears miraculously”.
In your letter to the White House, members of the committee of the National Academy of Sciences (NAS, for its acronym in English) said that the data are mixed on whether the coronavirus is so easily spread in warm climates as in cold climates, but that might not matter much given that so few people in the world are immune to the coronavirus.
“There is some evidence that suggests that [el coronavirus] can transmit less efficiently in environments with ambient temperature and humidity higher; however, given the lack of host immunity to the global level, this reduction in transmission efficiency may not lead to a significant reduction in the spread of the disease without the adoption of concomitant important public health interventions,” according to the letter.
The letter noted, for example, that a study of the outbreak in China showed that even in conditions of temperature and humidity maximum, the virus has spread “exponentially”, and that every infected person gave it to almost two other people on average.
Dr. William Schaffner, infectious disease specialist at the Medical Center of Vanderbilt University, who is not a member of the committee NAS, said: “Although we can hope that the weather will contribute to the reduction of transmission, we can’t rely on that alone. We have to keep using the social distancing and other measures to reduce the transmission.”
The president Trump has said that the coronavirus will recede with warmer weather.
“Many people think it disappears in April with the heat, as it enters the heat. Usually, this will go away in April,” said the 10 of February in a statement to the governors of the nation.
Trump repeated the idea later that day at a rally political in New Hampshire.
“It seems that in April, in theory, when it is heated a little, it disappears miraculously,” he said.
What he said for the third time that day in an appearance on Fox News.
“You know that in April, supposedly, dies with the warmer weather. And that is a beautiful date to wait for,” he said.
Schaffner, an adviser to the Centers for Control and Prevention of Diseases of EE. UU. (CDC), pointed out that the report NAS provides “a more instructive” of the situation Trump.
“The president walks on the sunny side of the street, and this takes us to the shady side of the street,” said Schaffner. “It makes us realize that spring probably will not be a total solution”.
The letter of the scientists of NAS notes that some laboratory studies have shown a reduced transmission of the virus in the warmer conditions and moist, but that remains a concern.
The letter described how Chad Roy, a researcher at Tulane University, submitted the virus to warm temperatures and moist in the laboratory, and studied for 16 hours.
Roy reports, “surprisingly,” that the new coronavirus have lived more time than the flu, monkey pox, tuberculosis, and the coronavirus that causes SARS, known as severe acute respiratory syndrome, according to the letter of the Standing Committee of Emerging Infectious Diseases and Health Threats of the TWENTY-first Century of the NAS.
The scientists sent the letter to Kelvin Droegemeier in the Office of Science and Technology Policy of the White House.
The letter notes that in the real world, the virus is still being transmitted in countries with warm climate.
“Given that countries are currently in a climate of ‘summer’, as Australia and Iran, are experiencing a rapid spread of the virus, it should not be assumed a decrease in cases with increases of temperature and humidity in other places,” according to the letter.
The letter also points out that, although the flu is generally seasonal, that is not necessarily the case when there is a new strain of the flu, and very few people have immunity.
New strains of flu have broken out in hot and cold climates, and then there was a second wave about six months after.
Dr. Paul Offit, infectious disease specialist, noted that while the coronaviruses that cause the common cold are seasonal, this new coronavirus is different because it is originated in animals, not in humans.
“It is not clear how this virus,” said Offit, professor of pediatrics at the Children’s Hospital of Philadelphia.
