Is it true that corona virus cant survive in hot weather, in summer it will stop spreading?

    coronavirus continues to spread across the world, a simple solution has been repeated by some leaders: Warm summer temperatures will stop the outbreak in its tracks.

    U.S. President Donald Trump floated the idea that by April the coronavirus problem would solve itself. He told a crowd at a Feb. 10 rally in New Hampshire: “You know, in theory when it gets a little warmer, it miraculously goes away, that’s true.”

    In Southeast Asia, officials in Indonesia have offered the warm climate as the reason that no cases have been diagnosed there. “Indonesia’s air is not like the air in China that is subtropical,” said Achmad Yurianto, a senior official in Indonesia’s health ministry, in response to a study suggesting there are likely to be undetected cases in the country.

    However, infectious disease experts say while the factors that cause other viruses to retreat during the summer months could affect this coronavirus, called COVID-19, in a similar way, there’s no way to be sure. And, even if the virus’ spread does slow as temperatures rise, that doesn’t mean it will be gone for good.

    Why cold and flu decrease in the summer

    There’s precedent for the idea that the COVID-19 outbreak will collapse with the onset of summer.

    The common cold is most prevalent in the winter and spring, and influenza is most common during the fall and winter in the U.S., with flu activity peaking between December and February, according to the CDC.

    It appears that COVID-19 is transmitted in the same fashion as the flu and common cold: by close contact with infected people and from respiratory droplets when an infected person sneezes or coughs.

    There’s a variety of reasons that influenza and cold infections plummet in the summer, but a major one is that that warm, humid weather can make it harder for respiratory droplets to spread viruses.

    “The droplets that carry viruses do not stay suspended in humid air as long, and the warmer temperatures lead to more rapid virus degradation,” says Elizabeth McGraw, director of the Center for Infectious Disease Dynamics at Pennsylvania State University.

    Human activity also changes in summer months, says Thomas Bollyky, the director of the Global Health Program at the Washington D.C.-based Council on Foreign Relations. People spend less time indoors—where they tend to be in closer contact with each other, making it easier for the virus to spread—in the summer.

    ‘Premature’ to assume heat will stop COVID-19

    But health experts aren’t so sure that COVID-19, which has infected more than 83,000 people since officials first discovered the disease in December, can be stopped by the onset of summer.

    Dr. Nancy Messionnier of the Centers for Disease Control and Prevention, warned against assuming the number of cases will slow as the weather warms. “I think it’s premature to assume that,” she said during a call with reporters on Feb. 12. “We haven’t been through even a single year with this pathogen.”

    Other health experts that TIME spoke to agree that it’s too early to say if warmer weather will impact the virus’s spread. McGraw, of Penn State University, says there will likely be many factors that determine when and how the outbreak ends. “Rate of virus spread, effectiveness of infection control practices, weather and human immunity will likely all play a role in determining its future,” she says.

    Additionally, because COVID-19 is so new, “there is no natural immunity in the population and thus all bets are off,” says John Nicholls of the University of Hong Kong.

    Looking at two other deadly members of the coronavirus family, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), could, Bollyky says, help us understand how COVID-19 may act in the summer heat. “Past coronavirus outbreaks, SARS and MERS, haven’t really exhibited clear evidence of being seasonal,” Bollyky says.”The SARS outbreak did end in July, but it is not clear that weather. MERS does not show any sign of being seasonal.”

    It isn’t summer everywhere at once

    Though the largest clusters of the coronavirus are in locations above the equator—mainland China, South Korea, Italy, Japan and Iran—the virus has now spread to all continents except Antarctica. This includes countries like Brazil and Australia in the southern hemisphere.

    Experts caution that even if the seasonal change in the northern hemisphere brings a reprieve in the number of cases, it may mean that other places become more susceptible to its spread.

    The southern hemisphere will begin their winter season within the next few months, potentially leading to a global reversal in transmission hotspots,” says Melissa Nolan, a professor of epidemiology at the University of South Carolina’s Arnold School of Public Health.

    Even if COVID-19 wanes in summer, it might come back

    And experts warn that even if COVID-19 becomes less active in the summer, it could return if public health officials do not gain control of the outbreak first.

    “If we continue to see sustained transmission in multiple countries, it will be very difficult to eradicate the virus,” says Charles Chiu, a professor of laboratory medicine at the University of California, San Francisco. “There is a risk that it may end up becoming a seasonal virus without global concerted public health interventions to prevent spread.”

    He points to the 2009 outbreak of the H1N1 virus, otherwise known as swine flu, which began in April of that year. He says that as it adapted to the human population, it adopted a seasonal pattern, with most infections now occurring during the winter months.

    Others agree that officials must not be complacent as the summer months approach.

    “Policymakers and health officials should not rely on warmer temperatures to save us from COVID-19,” Bollyky, of the Council on Foreign Relations, says. “The only things that can do that are public health preparedness and level-headed policies to reduce the number of people infected, protect healthcare workers, and improve the diagnosis and treatment of those who do get ill.”

    No. I know Trump said that but he's a drug addicted, demented moron. He also said the mortality rate was made up and that it's safe for people to go to work even if they're sick. With Mile Pence in charge of the USA's response to covid-19 it's going to get ugly.

    It's predicted to behave thusly, then to bounce back, with revenge, at Autumn's 1st gold leaf, much like the Spanish flu.

    There is no scientific basis for this .... unless you are talking temperatures hot enough to boil water.

      It is more that people spend more time outdoors and stand further apart in hot weather so are less likely to transmit a virus. Which is why contagion ramps up again as soon as weather starts to cool. Hot here in Australia at the moment and it is spreading here. Also spreading in areas near equator.

    I doubt the coronavirus will stop spreading.

    It probably won’t “stop” the spread, but there’s a good chance that it will slow down drastically. The flu has a season, for instance, but it’s still around all year.
