COVID-19 Reinfection 'Highly Unlikely' For At Least Six Months: Study | KPRC

Other studies show that some people may be more infectious and deemed a superspreader because they have weak immune systems that allow viruses to replicate more quickly, thus leading to frequent symptoms like coughing and sneezing, McClatchy News reported in June.

Experts collated and scrutinised 98 papers to inform their conclusions.

Lead author author Dr. Muge Cevik of the University of St. Andrews, U.K. said in a statement that the new analysis "provides a clear explanation for why SARS-CoV-2 spreads more efficiently than SARS-CoV and MERS-CoV and is so much more hard to contain".

"This is the first systematic review and meta-analysis that has comprehensively examined and compared viral load and shedding for these three human coronaviruses", said study lead author Muge Cevik from the University of St. Andrews in the UK.

In contrast, the viral loads of SARS and MERS-CoV peaked at 10-14 days and 7-10 days after symptom onset, respectively.

"It provides a clear explanation for why SARS-CoV-2 spreads more efficiently than SARS-CoV and MERS-CoV and is so much more hard to contain", Cevik added.

Four produce the symptoms of the common cold and immunity is short-lived.

In the current study, 80 individuals were recruited and allocated into one of two groups, an MMR II group consisting of 50 subjects who primarily had MMR antibodies from the MMR II vaccine, and a comparison group, consisting of those with no record of MMR II vaccinations, and who would have obtained any MMR antibodies from other sources such as prior infections with measles, mumps, or rubella. A delirium diagnosis was the main presenting symptom for 16% of those patients, and 37% had no typical COVID-19 symptoms.

The new research reinforces previous studies that used contact tracing and determined spread happened fastest at the onset of infection. "But beware, we have little feedback on this disease".

The study's researchers found an inverse correlation between levels of mumps titers and the severity of COVID-19 disease symptoms in those who had been vaccinated with the measles-mumps-rubella MMR II vaccine.

Professor Lawrence Young, of Warwick Medical School, said today: "The significant take-home message is that the immune response... is more long-lived than previously thought".

American researchers from the Jolla Institute for Immunology (California) have just published the most complete study conducted on immunity to Covid-19.

"We are therefore confident that the majority of people who have survived SARS-CoV-2 infection have some protection against reinfection with SARS-CoV-2", he added.

It also looked at isolation of the live virus - a stronger indicator of a person's infectiousness, as the live virus is isolated and tested to see if it can successfully replicate in the laboratory.
