Survival of Severe Acute Respiratory Syndrome Coronavirus (2005)

This research paper was published in 2005 and relates to SARS-CoV (responsible for the 2002/03 SARS outbreak), not SARS-CoV-2 (responsible for COVID-19). However, since these two viruses are closely related, it is insightful to observe what is known about the former, in order to consider what may be possible (or even likely) for the latter.Continue reading “Survival of Severe Acute Respiratory Syndrome Coronavirus (2005)”

Stability of SARS-CoV-2 as compared with SARS-CoV-1

This study examined the survival and infectivity of SARS-CoV-2 (COVID-19) and SARS-CoV-1 in air and on solid surfaces. A concentration in the same ballpark as the amount coughed out by an infected person was incorporated into aerosolised droplets which were either kept inside an enclosed drum for 3 hours, or were deposited onto stainless steel,Continue reading “Stability of SARS-CoV-2 as compared with SARS-CoV-1”

Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents

This review of previously reported studies was published in March 2020, so provides a very current update on the persistence of (human and veterinary) coronaviruses (such as SARS-CoV-2) on surfaces and their inactivation with potential disinfection reagents. The analysis of 22 studies revealed that human coronaviruses such as SARS-CoV, MERS-CoV or endemic human coronaviruses (HCoV)Continue reading “Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents”

Human Coronaviruses: Insights into Environmental Resistance and Its Influence on the Development of New Antiseptic Strategies

This paper does not discuss the presence or fate of coronaviruses in water, but it includes useful insights on disinfecting agents. Some of these (most notably sodium hypochlorite) have relevance for drinking water and wastewater management. But many of them have relevance to the water industry in that these disinfectants may have important roles forContinue reading “Human Coronaviruses: Insights into Environmental Resistance and Its Influence on the Development of New Antiseptic Strategies”

Effects of Air Temperature and Relative Humidity on Coronavirus Survival on Surfaces (2010)

This paper does not specifically address the fate of coronaviruses in water. But it reports some relevant facts that affect the survival of coronaviruses on surfaces. These are the importance of air temperature and relative humidity. This research was undertaken using surrogate viruses in order to avoid the challenges of working with the highly pathogenicContinue reading “Effects of Air Temperature and Relative Humidity on Coronavirus Survival on Surfaces (2010)”
