I watched just a few minutes of this morning's press confernce. Within seconds I encountered the first lie: that it is impossible to get reinfected with the virus once contracted.I had the answer, here, within minutes.

S. Korean woman reinfected
with coronavirus after
recovery

Yonhap News,
29 February, 2020

SEOUL, Feb. 29 (Yonhap) -- South Korea reported the first case of reinfection by the new coronavirus Saturday amid mounting concerns over the rapid rise in virus infections here.

A South Korean woman tested positive for COVID-19 a second time, even after being released from quarantine, according to the Korea Centers for Disease Control and Prevention (KCDC).

The 73-year-old woman, who was diagnosed with the virus earlier in the month, was released from a hospital on Feb. 22 after making a full recovery.

She started showed symptoms again Thursday and was found to have contracted the illness again Friday, the public health agency said.

"People normally would have become immune against the virus after being infected for the first time. The patient, however, may have a weak immune system due to her age," a KCDC official said.

The official added it is also possible the virus was not fully eradicated from the patient in the first place.

This is the first time in South Korea that a person has been infected a second time with COVID-19 after being discharged.

The woman had not traveled abroad, although her son and daughter-in-law had recently been to China's Guangdong Province, and both had contracted the virus.

Local health authorities said that the woman claimed she had stayed indoors after her release.

The KCDC said it is carrying out a close observation on the case and added there were 10 similar cases reported in China, the global epicenter of the COVID-19 outbreak.

South Korea reported a whopping 594 additional cases of the new coronavirus to bring total infections to 2,931 as of Saturday morning.

So far, 17 virus patients have died from the virus that emerged in China late last year.

South Korea said it will review revising its guidelines for people being released from quarantine following the new infection

Health experts have highlighted challenges with the coronavirus epidemic

, with the WHO warning of the risk of outbreaks coming back to life and researchers in mainland China and Hong Kong pointing out a major difficulty with diagnosis.

The alerts came on Friday as the World Health Organisation declared that the risk ofglobal spread of the coronavirus epidemic had become “very high” though the UN health agency stopped short of calling it a pandemic.

In a joint study published in the New England Journal of Medicine, researchers from mainland China and Hong Kong reviewed the cases of 1,099 coronavirus patients from 552 hospitals in 30 provinces.

They found that more than half the patients did not have a fever when they went into hospital, making diagnosis more difficult. But 88.7 per cent of them did develop one after admission.

“Some patients with Covid-19 do not have fever or radiologic abnormalities on initial presentation, which has complicated the diagnosis,” the study said, referring to the disease caused by the coronavirus.

The study was co-authored by dozens of medical experts, including Zhong Nanshan, director of China’s State Key Laboratory of Respiratory Diseases, and Chinese University of Hong Kong respiratory medicine expert Professor David Hui Shu-cheong.

So far, the epidemic has killed 2,835 people on the mainland, with 47 more fatalities on Saturday. Mainland China has 79,251 infections, with 39,002 patients recovered.

More cases have also been reported in South Korea, Italy and Iran, prompting the US Centres for Disease Control and Prevention to raise its travel advisory for Italy and Iran, recommending travellers avoid all non-essential trips to those countries due to “limited access to adequate medical care in affected areas”.

"Vaccinologist Dr Helen Petousis-Harris said from her understanding, the coronavirus wasn't showing many signs of mutating or changing.

"Generally, when you get changes in these sorts of viruses, they aren't necessarily going to be really bad."

If you are a vaccinologist perhaps you get used to lying?
