A study suggests testing and contact tracing and population behavioral changes—measures which have far less disruptive social and financial impact than total lockdown—can meaningfully control COVID-19.
Hong Kong seems to have avoided a major COVID-19 outbreak as much as March 31, 2020, by adopting far less drastic control measures than most different nations, with a combination of border entry restrictions, quarantine and isolation of cases and contacts, along with some degree of social distancing, based on a new observational examine featured in The Lancet Public Health journal.
The study estimates that the rate at which the virus is transmitted—known as the efficient reproductive number, or the average number of folks each individual with the virus is prone to infect at a given moment—has remained at roughly 1 in the 8 weeks since early February, after public health measures had been implemented from late January onwards, indicating that the epidemic in Hong Kong is holding regular.
As of March 31, Hong Kong had 715 confirmed COVID-19 infections along with 94 asymptomatic infections and four deaths in a population of about 7.5 million.
The public health measures implemented to suppress local transmission in Hong Kong are in all probability feasible in lots of locations worldwide, and could be launched in different nations with enough resources, researchers say.
