A team of clinicians here have reported what they believe to be the first known case of Covid-19 reinfection in Ireland. It involved a 40-year-old female health care worker who was first infected in April 2020.
The infection was laboratory confirmed and she did not need hospitalisation. Seven months later, she presented with symptoms and was found to have Covid-19, according to the study in the latest Irish Medical Journal.
On the second occasion, the symptoms were milder and recovery was faster. The authors of the case study say that the incidence of Covid-19 reinfection is not well characterised and that further research is needed on the nature and duration of immunity.
