“The CDC states that the risk of surface transmission is low and secondary to the primary route of viral transmission through direct-contact aerosols and aerosols,” said Vincent Hill, Head of Aquatic Disease Prevention, in a briefing at the CDC. Phones supported by the CDC
Hill said the risk of transmission from touching surfaces, while smaller, would be higher inside buildings. Outdoors, sunlight and other factors can destroy viruses, Hill said.
Viruses die “quickly” on porous surfaces. But can last longer on hard surfaces and indoors.
Research also suggests that surface transmission is more likely in the first 24 hours after a person is infected and that households with one person infected with Covid-19 have lower transmission rates as households cleanse. Clean and sanitize the surface
“In most situations, cleaning surfaces with soap or detergent and without sterilization is sufficient to reduce the risk of virus transmission through the surface,” Hill said. Surface, unless the sick person or someone thought to have Covid-19 was in the home within the past 24 hours. “
Hill said the focus should be on cleaning high-contact areas such as door knobs and light switches.
House cleaners are dangerous.
People may use household cleaning products to protect themselves from Covid-19, but their misuse can have dangerous consequences, Hill added.
Cleaning and disinfecting surfaces often can have the least impact on the spread of the virus and contribute to the “A theater for hygiene,” he added.
“Performances” to clean and sanitize It might be used to make people feel safe that they’re protected from viruses. But this can be a false sense of security if other precautions are taken, such as wearing a mask, being aloof. And hand hygiene is not being treated consistently, ”Hill said.
It can also make people feel the need to take part in these other important precautions. ”
Additional information suggests that disinfectants themselves may pose a risk.
“Public inquiries indicate that some people may accidentally drink, inhale or spray their skin with disinfectants, unaware that using this kind of disinfectant can cause serious harm to the body,” he said.
Hill cited CDC research as of June 2020, which showed that, according to a survey of those people, “only 58% know that bleach and ammonia should not be mixed due to bleach and Ammonia produces toxic gases that are harmful to people’s lungs.
And bleach can be dangerous.
Nineteen percent wash food products with bleach, which can lead to unwashed bleach, which can damage the body because bleach is toxic. Eighteen percent use household cleaners. With bare skin, which can damage the skin and cause Rash and burn marks, ”said Hill.
Hill added that surveillance data showed that the 2020 poison center call volume for the disinfectant was higher than in 2018 or 2019.
Alternative sanitizing methods can be time consuming or risky, the CDC said in the updated guidance.
“The efficacy of alternative surface disinfection methods such as ultrasonic waves, high intensity UV rays and blue LED light against COVID-19 viruses has not been fully established,” the CDC said on its website. Updated
