MOSCOW, 22 Aug — RIA Novosti. the new type of Coronavirus in contact with the river water may survive up to 25 days from the Preprint of a study published in the medical portal medRxiv.
this conclusion was reached by Polish and British scientists. They estimated the life expectancy of the virus in reservoirs subject to the ingress of sewage, as well as the risk of infection in case of contact with infected water system.
a Large leak during a pandemic coronavirus happened, particularly in the United States (in the States of Georgia, Florida and new York), and Spain (in the Autonomous community of Andalusia).
“Natural water systems can be a channel for the transmission of SARS-CoV-2 … We came to the conclusion that the virus can remain stable up to 25 days,” the study says.
scientists estimate that for infection COVID-19 in the reservoir the necessary concentration in the ratio of 100 viral particles per 100 milliliters of water. The highest risk of infection was discovered in countries with low volume consumption of drinking water, a high proportion of the infected population, and a weak dilution within the water bodies of wastewater.
a Relatively small threat of infection is identified, particularly in Canada, Norway and Venezuela.
also Noted the role of water temperature. So, the concentration of viral particles for a long time is highest in cold water.
“the analysis suggests that contact with rivers and coastal waters from sewage leakages should be minimized to reduce the risk of infection”, the study says.
the world health organization on 11 March announced the outbreak of a new coronavirus infection COVID-19 pandemic. According to the latest who data, the world revealed more than 8.7 million cases, more than 461 thousand people died.
