The Department of Disease Control is easing people’s worries about the spread of Covid-19, saying that low temperature won’t make the virus more transmissible. They say disinfectants and sunlight are still effective to kill the virus.

With cool weather in Central and Northern Thailand in recent days, some have been concerned that the low temperatures could impact the spread of Covid-19.

While the virus can live on surfaces for a longer time in low temperature, it can die fast if wiped clean or if it is under sunlight, according to Taweesap Siraprapasiri from the DDC.

He advises people to continue to abide by coronavirus prevention practice, like social distancing and avoiding crowded areas.

  1. In this article, The Disease Control Department says”…sunlight are still effective to kill the virus.”, but they made a contradictory statement in previous article “Cofact Debunks Top 5 Fake News….”

    “Standing in direct sunlight can kill the coronavirus – the Disease Control Department says this is not correct, clarifying that the coronavirus can be resistant to the heat up to 90 degree Celsius, but the temperature of the sunlight is not that high to make any effect. But you might end up with a bad case of sunburn.”

    It is not the temperature of the sunlight, but the type of Ultra Violet (UV) rays in the sunlight needed to kill the virus. The reason why sunlight can not kill the virus is because most of sunlight’s UVC rays (Sunlight has 3 different UV rays, UVA, UVB & UVC) do not penetrate the earth’s ozone layer to be effective. UVC rays in man made lights in direct high concentrations, have shown to kill viruses including Covid 19. As sunlight is mainly made up of UVA rays, along with UVB rays, the sunlight that reaches the earth’s surface, lacks the concentrated amounts of UVC rays to kill the Covid 19 or any virus.
