The information coming in is sounding worse than conspiracy theories do!
As the war of words rages in the UK, in a further blow to herd immunity theory, Jaap van Dissel, director of the Centre for Infectious Disease Control at RIVM explains, "Those with milder infections of Covid-19 generate fewer antibodies against the virus"
Jaap van Dissel "The first numbers show that those with a serious infection have a higher concentration of antibodies than those who have had a mild infection."
Researchers in Shanghai hope to determine whether some recovered
coronavirus patients
have a higher risk of reinfection after finding surprisingly low levels of Covid-19 antibodies in a number of people discharged from hospital.
A team from Fudan University analysed blood samples from 175 patients discharged from the Shanghai Public Health Clinical Centre and found that nearly a third had unexpectedly low levels of antibodies.
In some cases, antibodies could not be detected at all.
“Whether these patients were at high risk of rebound or reinfection should be explored in further studies,” the team wrote in preliminary research released on Monday on Medrxiv.org, an online platform for preprint papers.
At least 51 patients diagnosed as having fully recovered from the coronavirus in South Korea have tested positive a second time after leaving quarantine, according to officials.
The patients from Daegu all tested positive in a “relatively short time” after they were given the all-clear from their initial infections, the Korea Centers for Disease Control and Prevention (KCDC) said, according to the government-funded
Yonhap News Agency.
A specialist team has been sent to conduct an epidemiological investigation in the city, which is the epicenter of the epidemic in South Korea, the agency says.
For now, the KCDC’s director-general, Jeong Eun-kyeong, believes it is likely the infection was re-activated after remaining dormant in the patients, as opposed to them being reinfected, the report said.
