At the beginning of the epidemic, only highly symptomatic people and those in contact with them were tested. In order to avoid the risk of spreading the epidemic, they were mainly tested by RT-PCR in their homes by medical or paramedical staff.
A number of generalized testing protocols were subsequently set up for target populations such as law enforcement officers (firefighters, police officers, health workers) or teaching staff and students returning to school.
As from 19 May, Monégasque citizens and residents aged 5 years and over have been invited to be tested at specially equipped sites, from Monday to Saturday, from 8 a.m. to 6 p.m., by alphabetical order (first letter of the name of use) and on presentation of their identity card. These serological screening tests are carried out on a voluntary basis and are entirely free of charge.
As of 2 June, the same large-scale and free-of-charge screening campaign was introduced for Monégasque employees not residing in the territory. This campaign has proved particularly useful as approximately 50,000 commuters live outside the Principality but enter daily for work. This figure is significant in relation to the Principality's 38,300 inhabitants.
This screening campaign is based on the use of TROD, coupled with a quantitative test (blood test) in the event of a positive or doubtful result. To carry out this quantitative test, the persons concerned can go to the Princess Grace Hospital Centre, one of the Principality's four medical analysis laboratories or those present on French territory bordering the Principality (mainly Beausoleil).
A total of almost 35,000 people have been tested in the Principality and the prevalence rate has been fairly low at 2.8%.
Overall, Monaco’s quantitative testing capacities amount to about 440 per day. As far as RT-PCR capacities are concerned, those for sampling amount to around 60 per day and those for analysis to around a hundred. As far as ORT capacities are concerned, they amount to more than 3,000 per day.
