Hong Kong started a voluntary mass-testing program for coronavirus Tuesday as a part of a technique to interrupt the chain of transmission within the metropolis’s third outbreak of the illness.
The virus-testing program has turn out to be a flash level of political debate in Hong Kong, with many distrustful over sources and workers being supplied by the China’s central authorities and fears that the residents’ DNA could possibly be collected through the train.
The Hong Kong authorities has dismissed such considerations, saying that no private information will likely be hooked up to the specimen bottles and that samples will likely be destroyed in Hong Kong after the train.
The testing program started at eight a.m. with residents heading to greater than 100 testing facilities staffed by over 5,000 volunteers.
More than 500,000 individuals within the metropolis of seven.5 million signed up prematurely for this system, which is able to final at the least every week. It is aimed toward figuring out silent carriers of the virus — these with out signs — who could possibly be spreading the illness.
The authorities expects 5 million individuals will participate in this system, which could possibly be prolonged to 2 weeks relying on demand.
Hong Kong’s worst outbreak in early July was blamed partly on an exemption from quarantine necessities for airline workers, truck drivers from mainland China and sailors on cargo ships.
At its peak, Hong Kong recorded greater than 100 domestically transmitted circumstances a day, after going weeks with none in June.
The outbreak has slowed, with the town reporting simply 9 circumstances on Monday, the primary time in two weeks that day by day infections had fallen to single digits. However, the federal government and a few specialists say that neighborhood testing might help detect asymptomatic carriers to additional cease the unfold of the virus.
Respiratory medication skilled professor David Hui that although infections have dwindled, the proportion of circumstances with untraceable sources of an infection stay between 30% and 40%.
“That means there must be some silent transmission going on, so community testing has some role in picking up these silent transmitters,” mentioned Hui, who’s a public well being adviser to the town’s authorities. “Hopefully if we can identify these people and isolate them for a period of time that may help to break the transmission chain in the community.”
The program is more practical if many of the inhabitants takes half, Hui mentioned.
“If only 1 or 2 million people take part, then we may not be able to achieve that objective,” he mentioned.
Other specialists, comparable to Dr. Leung Chi-chiu, a respiratory specialist and a member of the Medical Council of Hong Kong, mentioned that the testing program performs solely a supplementary function in controlling the pandemic within the metropolis, as a result of lengthy and variable incubation interval of the coronavirus.
Leung mentioned that mass-testing might not be essentially the most cost-effective technique, as it isn’t straightforward to select up the illness in its early growth, particularly if an individual shouldn’t be having signs or haven’t had latest publicity to an contaminated affected person.
Even if mass-testing may establish contaminated sufferers, they could already be previous the infectious stage, he mentioned.
Leung mentioned that large-scale testing won’t be able to switch conventional strategies of social distancing and make contact with tracing measures, and may solely be used as a complementary measure.
