Abstract

Objective. Know the different prevalence and lethality in the Basic Health Zone (ZBS) of Benavente Norte between the first wave (until May 11) and the second wave (May 11 to November 30). Analyze the observed differences and their causes. Material and methods. Descriptive and transversal epidemiological study. All patients registered as Coronavirus Disease in MEDORA in ZBS of Benavente Norte were included. He took himself a computerized record with all positive cases confirmed by active infection screening (PDIA), those admitted, deceased, and followed at their homes and residences of the ZBS of Benavente Norte. Results. The ZBS. of Benavente Norte serves a population of 12,674 users. Of the 708 cases with positive PDIA (604 per PCR and 104 per rapid antigenic test) recorded up to day 30-11-2020 in MEDORA, 146 belong to the first wave, before May 11 and 562 to the second wave from May 12 to November 30 (prevalence: 5.58 %). In the first wave 11 patients died (lethality: 7.5%). In the second wave 17 patients died (lethality: 3.02%). Comments. We have chosen the date of May 11 to separate the two waves, due to the change in that date from the form of notification of the disease and the large decrease in the number of cases detected in mid-May. Conclusions. Prevalence (5.66%) and the fatality rate of the disease (7.5% in the first wave and 3.73% in the second wave) of 5.61% in our basic health zone have been high compared to prevalence and lethality nationwide as of November 30 (3.48% and 2.73% respectively). Despite this, we have managed to detect, track, and contain the pandemic in very acceptable terms, in addition to meeting the demand in the rest of the pathologies.
