‘Silent transmission’: COVID-19 largely spread by asymptomatic, presymptomatic carriers, study says

LOS ANGELES -- Asymptomatic individuals are believed by many scientists to be contributing to the rapid spread of the novel coronavirus, and a new study indicates that people with COVID-19 but who do not show symptoms may be behind most infections.Published in the Proceedings of the National Academy of Sciences, the July 6 study refers to the phenomena of COVID-19 infections by asymptomatic and presymptomatic individuals as “silent transmission.”The study says that even if symptomatic cases are isolated — such as a person being quarantined until they have recovered or tested negative for the virus — “a vast outbreak may nonetheless unfold.””We further quantified the effect of isolating silent infections in addition to symptomatic cases, finding that over one-third of silent infections must be isolated to suppress a future outbreak below 1% of the population,“ according to the article abstract.The researchers used 10,000 hypothetical people representing the demography of residents for New York to populate their model.”Transmission was implemented probabilistically for contacts between susceptible and infectious individuals in the presymptomatic, asymptomatic, or symptomatic stages,“ according to the study. ”A proportion of infected individuals remained asymptomatic through recovery,“ with those subjects having an ”average infectious period“ of five days.”Combined with case isolation, our results indicate that 33% and 42% detection and isolation of silent infections would be needed to suppress the attack rate below 1%“ based on asymptomatic proportions of 17.9% and 30.8%, the study states.While health experts have frequently stated that asymptomatic individuals are contributing to the spread of the novel coronavirus, it’s been unclear just how much they may fueling new infections, as well as if asymptomatic spread may be impacting spikes in cases as states and cities in the U.S. reopen parts of their economies.Earlier in June, the World Health Organization walked back comments that one of its officials had made on how asymptomatic transmission was ”rare.“ Maria Van Kerkhove, the WHO official who made the comments, later clarified, calling the comments a ”misunderstanding.““The majority of transmission that we know about is that people who have symptoms transmit the virus to other people through infectious droplets, but there are a subset of people who don’t develop symptoms and to truly understand how many people don’t have symptoms, we don’t actually have that answer yet,” said Van Kerkhove at a June press briefing.It is now believed by hundreds of scientists in dozens of countries around the world that the coronavirus is airborne, meaning that individuals can contract COVID-19 simply by breathing in air in a space that was previously occupied by an infected person.

Bill Nye demonstrates effectiveness of COVID-19 mask materials on TikTok

COVID-19 heroes must jump through hoops for workers' comp

WASHINGTON — Lauded for their service and hailed as everyday heroes, essential workers who get the coronavirus on the job have no guarantee in most states they'll qualify for workers' compensation to cover lost wages and medical care.Fewer than one-third of the states have enacted policies that shift the burden of proof for coverage of job-related COVID-19 so workers like first responders and nurses don't have to show they got sick by reporting for a risky assignment.Debate over workers’ comp in the states is part of a much larger national discussion about liability for virus exposure, with Republicans in Congress seeking a broad shield for businesses in the next coronavirus relief bill.And for most employees going back to job sites as the economy reopens, there's even less protection than for essential workers.
