![]() ![]() You also don’t necessarily have to be in the company of someone who has the virus either. We’ll discuss this a little more in the next section. This is called presymptomatic transmission. It’s also possible to transmit the virus before you develop COVID-19 symptoms. It found that asymptomatic individuals presented a significant risk for the virus to spread to their contacts. This is called asymptomatic transmission.Ī May 2021 study followed workers participating in a mass screening program for COVID-19. There’s also a possibility that someone who has the coronavirus can transmit the virus even if they don’t develop symptoms. When droplets containing the virus enter your nose, mouth, or eyes, you can contract the virus. SARS-CoV-2 spreads mostly from person to person through respiratory droplets that are transmitted when a person with the virus talks, laughs, sneezes, or coughs. The average incubation period is estimated to be around 5 days after exposure to the virus. SummaryĪccording to the CDC, the incubation period for the coronavirus is between 2 and 14 days after exposure. Researchers found that the incubation period of the Delta variant was 4 days, which was 2 days shorter than the 6-day incubation period they observed for the original strain of SARS-CoV-2. This variant replicates at a faster rate and to higher numbers than previous strains of the coronavirus.Ī September 2021 study compared the Delta variant to the original strain of SARS-CoV-2. The incubation period appears to have shortened with the emergence of the Delta variant of SARS-CoV-2. The average incubation period was estimated to be around 5 days. The virus that causes COVID-19 is inactivated by the disinfection methods used in wastewater treatment.What is the incubation period for the new coronavirus?Ĭurrently, according to the CDC, the incubation period for the coronavirus is somewhere between 2 and 14 days after exposure.Ī report published earlier in the pandemic found that more than 97 percent of people who contract SARS-CoV-2 show symptoms within 11.5 days of exposure. Wastewater treatment plants use chemical and other disinfection processes to remove and degrade many viruses and bacteria. There is no information to date that anyone has become sick with COVID-19 because of direct exposure to treated or untreated wastewater. ![]() Genetic material from the virus that causes COVID-19 has been found in untreated wastewater (also referred to as “sewage”). There are no scientific reports of the virus that causes COVID-19 spreading to people through the water in lakes, oceans, rivers, or other natural bodies of water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or kill the virus that causes COVID-19. Natural Bodies of Water (Lakes, Oceans, Rivers) The virus that causes COVID-19 has not been detected in drinking water. ![]() There is also no current evidence that people can get COVID-19 by drinking water. Do not wash produce with soap, bleach, sanitizer, alcohol, disinfectant, or any other chemical. Follow food safety guidelines when handling and cleaning fresh produce. ![]() There is no evidence to suggest that handling food or consuming food can spread COVID-19. ![]()
