Quarantines Deemed As Non-Effective

China health authorities in Guangzhou’s Liwan district are reporting clinically observed situations where (please click here to see report in Mandarin language) a quarantined family of family of six having been isolated for 30 days without any outside contact and were initially tested negative upon the start of their quarantine, started developing symptoms after 30 days and only then tested positive for the coronavirus.

This case would add to evidence that challenges the current medical understanding of the disease’s incubation period, or the time it takes for a growing pathogen to reach a quantity necessary to produce symptoms in the host.

A previous study of more than 1,099 coronavirus patients by Chinese scientists, published in early February as a preprint, or a paper that has not been peer reviewed, has already made the case that the incubation period could be as long as 24 days, rather than the 14-day maximum previously believed.( https://www.thailandmedical.news/news/alarming-news-new-chinese-research-on-coronavirus-finds-incubation-period-of-up-to-24-days)

Another development lead experts to believe that it could be as long as even 27 days. (https://www.thailandmedical.news/news/breaking-news-new-coronavirus-can-incubate-for-as-long-as-27-days-before-showing-symptoms)

In another anomaly in Xinyang, a city in Central China’s Henan province, Health officlas announced on Feb. 16 that local authorities had diagnosed a “highly unusual” case where a patient tested positive on a third screening, some 34 days after leaving Wuhan.

Another documented case involved a person in Zhongshan, Guangdong, who had undergone a routine two-week quarantine after arriving from Hubei on Jan. 26 tested positive almost 31 days later.

Chinese epidemiologist Dr Zhong Nanshan, who discovered the SARS coronavirus in 2003 and co-authored the 1,099-person study, at a Feb. 18 press conference, said that he did not find the longer incubation periods to be strange, explaining that there are always exceptions.

Of the Covid-19 patients studied, 13 had incubation periods longer than 14 days, though the majority developed signs of illness within two to seven days of contracting the virus, Zhong said.

However it is now appearing that the number of such cases are actually much more than initially thought of.

Medical experts are now saying that as the time prolongs from the time the coronavirus was first discovered , more and more clinically observed studies will show that the incubation period for this disease could even be limitless, indicting a unique nature of this new coronavirus.
