So, if on the day of June 4, according to the Center for Public Health, 11,235 PCR tests were carried out in Ukraine, then with each next day their number decreased and by June 8 this figure was 6,359. Roman TsOS, Director of the Department of Infectious Disease Surveillance The homeland explained to the site 24 channels why the number of tests done is decreasing and whether this can be interpreted as a decline in the incidence rate.
Important Coronavirus in Ukraine: statistics and the number of infected
When we analyze the data on incidence, we should not forget about the indicator, which, in fact, determines the number of studies – this is the number of suspicions.
When a person has symptoms characteristic of coronavirus disease, a smear is taken from him and delivered to a laboratory center for examination. If there is little suspicion, then, accordingly, there will be a small amount of laboratory research.
If we look at the number of suspicious cases over the same last 5 days, we can see that the number of suspicions has almost halved. This means that people did not go to the doctors – perhaps because of the weekend. And, accordingly, the doctors didn’t take the swabs and deliver them to the laboratory,
– noted Roman Rodina.
At the same time, he notes: laboratories operate 24/7 and their workload does not depend on whether it is a day off or a working day.
In some regions, due to the large number of samples for research in laboratories, there were queues. Now they have mainly decreased, in particular in Kiev, or they are not there at all. Previously, the laboratory, with a small number of suspicious cases, could make those samples that stood in line. If there is no line, then, respectively, and samples, too.

It consists in the fact that the Ministry of Health has changed the testing strategy and introduced the tests of immuno-enzyme analysis (ELISA). They are now tested by doctors every 14 days, border guards, law enforcement officers, the National Guard – that is, those specialists who most often come in contact with people.
If earlier they were all tested by PCR, now by ELISA. And you can see that the number of tests by the latter method is gradually increasing. This is the so-called redistribution of research types. For example, a hospital with an IFA device can test its doctors – their samples will not go to the laboratory center and wait there in the general queue. This is the unloading and optimization of research in general.

When the pandemic will decline
In addition, although the number of samples is becoming smaller, the effectiveness of the study — the number of patients identified, the percentage of the total — remains the same. And to say that there is an increase or decrease in the incidence rate is possible only when there will be the same number of samples.
For example, when more than 11 thousand tests were done per day, more than 550 of them were positive. If we calculate this percentage and the percentage of positives now, then it does not decrease,
– explained Roman Rodina.
Yes, this may be due to the fact that the disease is on the decline. But, according to the expert, it’s worth recalling, for example, that last week there were several record numbers that were connected, in particular, with the fact that people did not follow the rules that were introduced with the weakening of quarantine. In particular, this applies to travel in public transport.
“Contact is tight and the likelihood that a person will be infected is significantly increased. Therefore, it is very important to comply with the existing rules of restrictions – quarantine is not over yet,” the specialist summed up.
As of June 10, the number of new cases of COVID-19 infection in Ukraine increased – 525 people fell ill during the day. The total number of people with this diagnosis is 28,381. Over the past day, 8,496 PCR tests have been performed.
