COVID-19 IMMUNITY MAY ONLY LAST A FEW MONTHS SAYS LONDON HOSPITALS STUDY, INCREASING THE NEED FOR RAPID TESTING

People who have recovered from Covid-19 may lose their immunity to the disease within months, according to research suggesting the virus could reinfect people year after year, like common colds.

Blood tests revealed that while 60% of people marshalled a “potent” antibody response at the height of their battle with the virus, only 17% retained the same potency three months later. Antibody levels fell as much as 23-fold over the period. In some cases, they became undetectable.

Re-infection would be less severe for any individual as they will still retain immune memory allowing them to more rapidly respond. Nevertheless they could still be a source of onward transmission.

This draws even greater attention to the need for mass rapid testing and the ability to isolate areas quickly. Outbreaks will keep happening and “Targeted action” is being taken against more than 100 local outbreaks of coronavirus every week, Health Secretary Matt Hancock has said.

Writing in the Daily Telegraph, Mr Hancock said increased testing meant officials could now be “targeted” in their response. His comments came after 73 cases of Covid-19 were confirmed at a farm in Herefordshire. Around 200 workers have been told to self-isolate following the outbreak.

TTSs solution is now CE certified. The Conformitè Europëenne (CE) Mark is defined as the European Union’s (EU) mandatory conformity marking for regulating the goods sold within the European Economic Area (EEA) since 1985. The CE marking represents a manufacturer’s declaration that products comply with the EU’s New Approach Directives. Its ability to provide results in 45 minutes at the point of testing coupled with an immediate mobile status update should be a core component of the approach for “targeted action”.
