Ask a question about Covid… August 11, 2022

Posted by WorldbyStorm in Uncategorized.

Raised the issue of how many people haven’t caught Covid in Ireland on Monday and here on Wednesday a report in the Irish Times brought this news.

Three out of four people in Ireland have been infected with Covid-19, data from the State’s infectious diseases monitoring body indicate.

More than two years on from the start of the pandemic, the entire population shows evidence of antibodies to Covid-19 through previous infection or vaccination, according to tests on blood samples carried out for the Health Protection Surveillance Centre (HPSC).


Latest monitoring shows 74.3 per cent of people have S+N+ seroprevalence for the virus, which is generally indicative of previous infection, and 100 per cent have S+ seroprevalence, indicating prior infection or vaccination.

Also, this is useful:

Evidence of previous infection is highest among 20 to 29 year olds, at 87 per cent. This figure falls to 81 per cent among those aged 30-49, and 63 per cent for 50-79 year olds.

While the presence of Covid-19 antibodies indicates previous exposure to the virus or a vaccine, the chance of reinfection remains uncertain. Recent variants have proved effective at reinfecting people, even months after a previous infection.

The report notes that the blood samples come from the blood donor programme and hospital labs and may be slightly skewed since generally only healthier cohorts go forward for the former. But still, 25% or so of the population still hasn’t caught it. As far as I’m aware, I’m in that cohort, unless somewhere along the line I caught it and was asymptomatic. 

Not sure whether to find that surprising or not.
