Dnevnik publishes current data related to the spread of the coronavirus in Bulgaria, provided by the Unified Information System. Below in the article you can see graphs that show the trends of recent months according to the main indicators – number of infected, composition and cure number of patients in hospitals and intensive care units and the ratio between the total number of control PCR and antigen tests and their results. When specifying a section of the chart (with the mouse for desktop version or with the finger for mobile) data for a specific day are evaluated. By pressing the buttons in the legend, individual components of the graphics can be moved.

As of December 23, 2020, the statistics also include data on antigen tests. Until these data, the only officially recognized by the state are PCR tests, according to Chief State Health Inspector Angel Kunchev latent morbidity (the number of infected detected by antigen test, but not confirmed by official PCR) is on average about 10-15%. And not all antigen tests are covered, but only those performed in laboratories, hospitals and clinics. There are many people who test themselves with the products offered in pharmacies, so there is still a hidden morbidity.

The first table shows the data for the past day, which often have inaccuracies due to technical reasons. On Sunday and Monday, the usual sharp decline in the number of new infections and the reason for the tests, and according to the authorities, is that on weekends many laboratories do not work or work at reduced capacity, and that laboratories and hospitals report late in the unified information system. This is one of the cases with a large increase in data on new infections, hospital stays and deaths.

In an attempt to “smooth out” the incidental peaks and troughs in brackets to the main indicators is indicated the change in% for the last seven days from the date of the communication based on the daily average (Monday is compared with the previous Monday, Tuesday with Tuesday, but not in absolute terms, but after averaging for the period, etc.).

Infected, cured, included

After 23 December 2020, official statistics report as infected people for whom a positive PCR or antigen test has been obtained in state laboratories or COVID centers.

After October 13, 2020 statistics reported as cured all infected, a wonderful 14-day quarantine has expiredwithout delivering research. All patients who were hospitalized with COVID-19 and discharged are also considered cured. The statistics of victims include people who have been used after being diagnosed with coronavirus. According to this indicator, since the beginning of the epidemic in many countries there is a dispute over how correctly it is reported due to the role of accompanying patients.

How good are the tests

The calculation of what part of the tests are based is somewhat conditional, as by doing the total number of tests for the day, as authorities do not distinguish how many of the results come from the study for the first time and how good they are for the same patient. All of them can still be used for guidance, insofar as it should be necessary after the waiver of the mandatory negative quarantine test.

Hospital treatment

The need for hospital treatment is considered one of the key indicators for the development of the pandemic, as it puts serious pressure on the health system and it is possible to solve the crisis. According to the latest statements of the health authorities, they will experience insurmountable difficulties if the number of people hospitalized exceeds 10,000.

Vaccination

The vaccination campaign in Bulgaria started on December 27, 2020. With three of the preparations used so far – at Pfizer https://www.dnevnik.bg/ “BionTech”, “Modern” and “Astra Zeneca” / Oxford University, course is considered complete after two added doses over a period of time. So far, the only application of Jansen requires only one injection.

The authorities of several indicators – the total number of added doses (regardless of the first or second) so far, daily and the number added to the second dose, ie. with completed vaccination. In the graph you can see the ratio between the main doses administered and the actual number of graduates of the vaccination cycle.
