Take note – story published 2 years ago

Data published January 10 by the Disease Prevention and Control Center (SPKC) shows that in December, the booster vaccine made a significant difference in getting infected with Covid-19 and subsequently, hospitalization.

In December, in Latvia, people with primary vaccination had the Covid-19 infection 1.7 times less frequently than unvaccinated or partially vaccinated, while those who had also received booster vaccination were reported 5.5 times less frequently.

Vaccinated people ended up in hospitals 3.1 times less frequently than unvaccinated/partially vaccinated patients, but those who also had a booster shot were hospitalized 7.5 times less frequently. A comparison of the incidence of deaths (per 100 000 inhabitants) shows that the risk of deaths of people with primary vaccination in December in Covid-19 infections was 5.5 times lower than in non-vaccinated/partially vaccinated, but for those who had received booster vaccination the risk of death with Covid-19 was 24 times lower.

Last week, from January 3 to January 9, the number of reported new Covid-19 cases increased by 93.7% The number of patients in hospitals has also increased by 50.3%, with 71 people entering hospitals daily on average

On average, 10,220 (previously 6,633) tests were carried out per day, while on average 1,547 new cases were detected (799 the week before) per day. Of all tests performed, 4% (3,171 tests) involved screening of educational establishments, while 96% (68,366 tests) were in the rest of the population. Of the positive cases of Covid-19, 2% (267 infected) were associated with the screening of educational establishments, while 98% (10,563 infected) were in the rest of the society.

The reproduction rate of Covid-19 infection (R) has risen sharply in the last week to 1.6 (the week before 1.13), which shows a rapid spread of infectious disease in society.

Last week, Covid-19 infection was reported equally frequently in vaccinated as in unvaccinated/partially vaccinated people in Latvia, but 2.7 times less in those who had also received a booster vaccine.
