Until we reach herd immunity milestones for Kovid-19, when 75 percent to 90 percent of the population is immunized through communal exposure or vaccination, we will be wearing masks, socially disturbed, and glass. Closed bank will live in teller’s world. Lysol dependence. But an underused device can make a significant difference in identifying and combating the spread of viruses without disrupting one’s life or surroundings: environmental testing.
By sampling and measuring the presence of viruses within a given community, environmental testing can identify viral presence weeks before other measures.
Environmental sampling is an unbiased and ambiguous approach to explain where the disease is spreading. Any person who produces a virus – symptomatic or asymptomatic – spreads these viral particles into the environment. Most will become inactive due to harsh conditions outside the human body. However, as we have seen in tracking the rapid spread of viruses worldwide, some particles remain infectious on surfaces and in the air.
By sampling and measuring the presence of viruses within a given community, environmental testing can identify viral presence weeks before other measures, such as contact tracing. Among the benefits, which allows health care groups to localize outbreaks and targeted contact tracing in these areas.
Environmental testing has traditionally been a staple tool in investigating viral outbreaks, providing initial recognition, and tracking new cases. During the 2013 Netherlands measles outbreak, environmental sampling was able to correlate the amount of virus in normal water samples with the number of clinical cases. When polio outbreaks were being monitored in Pakistan, environmental testing at polio outbreak occurred four months before symptoms developed.
The last year has also shown the ability of scientists to stay home in new Kovid-19 cases in our communities and hospitals. Sewage sampling in college campuses and cities, for example, has been demonstrated to act as a cosmic canary in a coal mine, suggesting the silent presence of viral particles. This allows a small proportion of the population to be tested individually so that the virus can be identified by shedding people before disaster strikes. Surface and air samples provide similar “footprints” where recent viral shedding has occurred.
Despite its ability to solve the problem of hot zones of transmission, in hospital settings or in commercial campuses, there has been no push to include viral samples in the national viral surveillance strategy. Thus, the US plan to stop Kovid-19 has focused primarily on social control and contact tracing.
Social protection rests on the desire of more and more populations to strictly adhere to the rules about masks, social distance and quarantine. Contact with tracing, along with monitoring techniques such as symptom detection, overlooks the hazards of those who spread asymmetrically. Environmental testing, however, can provide comprehensive, continuous monitoring that provides community-tailored yet anonymous results.
The primary obstacle preventing comprehensive environmental testing is the lack of investment in developing sensitive detection methods. This can be overcome with the same simplicity that was brought to our scientific mind to develop the Kovid-19 rapid test, antibody test and, ultimately, vaccines.
Until then, there are many opportunities for states to implement this necessary tool without sophisticated new tools. As the government considers the allocation of the Kovid-19 relief fund, some of these resources should be used to allow virus hunters to perform simple and inexpensive processing of swabbing surfaces, collecting sewage water and air samples And transporting materials to laboratories to determine the wiring shed in the key. Area.
Using environmental sampling of places with high prevalence risk, such as schools and nursing homes, contact tracing regimens can focus on new outbreaks before system tracing spreads, and public lockdown confirmation may be limited to outbreak areas .
Similarly, hospitals try to maintain treatment for those with common ailments while providing optimal care for new surgeons of Kovid-19 patients. Without applying environmental samples to detect viral spread, many facilities are flying indiscriminately as to what type of protection they need and where to focus their resources.
By part of our arsenal’s environmental testing against this virus, we can create a safe environment for patients receiving essential medical care, localize key sources of spread in our community, and identify where novel strains have systemically Has created a new risk of proliferation.
