The number of people testing positive for COVID-19 has increased from 4,485 to 5,741 cases (+28%) for the week of 27 June to 3 July.

The number of PCR tests performed during the week of 27 June to 3 July has increased from 11,131 to 14,201.

53 people reported a positive rapid antigen test (RAT) for the reporting week, compared to 44 the previous week, bringing the number of positive results performed by a health-care worker to a total of 3,208. It should be noted that positive RATs are not included in the calculation of the positivity rate.

As of 3 July, the number of active infections has increased to 10,488 compared to 8,834 on 26 June, while the number of people healed increased from 251,237 to 255,322. The average age of those diagnosed as positive for COVID-19 is 39.9 years.

For the week of 27 June to 3 July, 2 new deaths related to COVID-19 have been reported. The average age of the deceased is 69 years.

In the hospitals, there were 19 new admissions of confirmed COVID-19 patients in normal care, compared to 13 the previous week. The number of occupied beds in the intensive care unit decreased from 2 to 1. The average age of hospitalised patients is 53 years.

Positivity rate and incidence rate

For the reference period, the effective reproduction rate (R) decreased, with 1.02% compared to 1.11% the previous week, while the positivity rate on all tests performed (prescriptions, contact tracing) increased from 40.29% to 40.43%.

The 7-day incidence rate increased to 890 per 100,000 inhabitants, compared to 695 per 100,000 inhabitants the previous week.

Re-infections as well as certified self-tests were included in the calculation of incidence rates. The incidence rate has increased in all age groups, except in the 0-14 and the 85+ age groups.

The largest increase was recorded in the 70-74 age group (+70%) and the 20-29 age group (+61%) The lowest incidence rate is recorded in the 75+ age group (515 cases per 100,000 inhabitants), while the highest incidence rate is recorded in the 30-44 age group with 1,509 cases per 100,000 inhabitants.


With the number of cases increasing, it is difficult to call, review and determine the likely source of infection for all cases over the past week at the time of writing this report. Priority for calls is given to cases over 60 years of age and to residents of care homes. Among the 7,766 cases registered with residents of care homes in the week of 27 June to 3 July, 3,455 cases were called before 4 July 2022.

After random selection of the cases called, 300 cases (8.7%) were reviewed and the source was determined. The family circle remains the most frequent source of transmission of COVID-19 infections (24%), followed by travel abroad (19%) and leisure activities (14%). The percentage of undetermined sources is 26%.
