Introduction: the SARS-CoV-2 pandemic affected a large part of the population of La Libertad, among them, the population of Florencia de Mora whose hospital played an important role in the care of patients diagnosed with COVID-19. Objective: to determine the epidemiological clinical characteristics of patients diagnosed with SARS-CoV-2 treated at the care center. Methods: Retrospective observational descriptive study, with a population of 2622 patients treated in the COVID-19 triage, taking into account the molecular test and the rapid serology test for the detection of SARS-CoV-2. Results: SARS-CoV-2 was detected in 74.90% (1155) of patients. The months with the highest number of cases were June and July with 29.4% (340) and 37.4% (432), respectively. The predominant age group was 27- 59 years with 77.9% (900) and males with 57.5% (664). Regarding the clinical profile, the most frequent comorbidity was hypertension with 6.9% (80), obesity and overweight with 3.7% (43) and the most frequent symptoms were cough 62.9% (726) and odynophagia 55.7% (643). Conclusions: 75 out of 100 screened patients had SARS-CoV-2, predominantly males, the age group of 27-59 years, hypertension, obesity and overweight as comorbidity, cough and odynophagia as the most frequent symptoms.

Keywords: Epidemiology, clinical picture, prevalence, SARS-CoV-2. (Source: MeSH NLM).

SARS-CoV was responsible of the first pandemic in the XXI century which extended to 29 countries, reaching a mortality of 9.6%. The second pandemic was caused by MERS-CoV in 2021 in the Middle East, reaching a mortality of 34.4% (1). In January 2020, the World Health Organization (WHO) declared a Health Emergency (1,2) and two months later it was considered a global pandemic due to COVID 19(3).

The human coronavirus strains are transmitted during winter and are responsible for the common cold (1,4,5), otitis media in children, and pneumonia (4,5), others are highly pathogenic, responsible for severe acute respiratory syndrome and Middle East Respiratory syndrome, respectively (5,6).

SARS-CoV-2 is a beta-coronavirus that is transmitted by airway (1,4), through fomites (4), fecal oral (7,8), and maternal-fetal (9). The airway route is the main mode of transmission through flügge droplets that are spread up to two meters when speaking, sneezing, or coughing, and remain in the air for over 17 minutes (1,4,10). The fomite mode of transmission is due to the virus remaining on smooth surfaces, from 4 hours (1) to 5 days depending on the type of material (4,11); likewise, the oral fecal route is justified by the presence of viral RNA in feces even with a negative nasopharyngeal smear (9) and the result of infectious aerosols in the toilet, leading to a fomite transmission. Regarding maternal-fecal material, although it has not been proven yet, it still cannot be ruled out (9).

The SARS-CoV-2 virus enters our organism through the nose, mouth or eyes, and enters the cell through the angiotensin-converting enzyme receptor (ACE2) (1, 10-12); which is found in the pulmonary cytoplasmic membranes AT2, as well as ileum and colon cells, where they replicate (11). The incubation period is 3 to 9 days, with the maximum viral load 2.5 days before symptoms appear (10).

The most frequent symptomatology is fever, cough, myalgia or fatigue, dyspnea,1,8,10,11,13 sore throat, diarrhea, nausea and vomiting (1,8,10,11), abdominal pain (8,10,13), anorexia, dizziness, headache, altered sense of taste and smell (9,11), arthralgias (12), impaired consciousness, and urticarial or vesicular eruptions and purpura (11). These are resolved after 10 to 15 days, but the viral shedding continues (1).

Hospital I Florencia de Mora EsSalud was not included as a reference center for SARS-CoV-2 in Trujillo, however, due to the spread this virus has and the saturation of reference hospitals, it played an important role in offering health services for care of patients with COVID-19. Based on this, the objective of this study is to determine the clinical and epidemiological characteristics of patients diagnosed with SARS-CoV2.


Design and area of study

a retrospective, observational, descriptive study, from the review of the archive management system of EsSalud, of patients treated in COVID triage in Hospital I Florencia de Mora (HIFM).

Population and sample

the population included 2622 patients defined as suspicious treated in COVID-19 triage of HIFM- EsSalud, La Libertad, during March to August 2020. We included patients diagnosed with COVID-19 confirmed with serologic or molecular testing, and patients who were not found during the control and follow-up calls were excluded, as well as those who requested voluntary withdrawal.

Variables and instruments

to assess the clinical epidemiological characteristics. confirmed cases were determined by positive serological and molecular tests, according to the definition in the official epidemiological alert. Regarding epidemiological characteristics, we considered age, origin and sex, while in clinical characteristics, symptoms and comorbidity were included.


after obtaining permission from the institution, we proceeded to review the epidemiological sheets downloaded from NotiWeb, entering each sheet into a database for the epidemiological surveillance of each patient.

Statistical analysis

through epidemiological surveillance, the descriptive statistic, the information was analyzed creating frequency tables with single and double entry, with their absolute and relative values.

Ethical aspects

In HIFM - EsSalud there is no ethical committee, which is why we counted with the approval of assistance service and the coordinator of hospital training, keeping confidentiality of sensitive data and anonymity in data collection, of which only research personnel had access.


Out of a total of 2622 treated in COVID-19 triage of HIFM - EsSalud, only 58.85% (1543) underwent screening with the serological test method 94.5 % (1458), while molecular tests were 5.5% (85). Among the participants, 74.9% (1155) were diagnosed with SARS-CoV-2. It is important to mention that 5.54% (64) were hospitalized and 1.99% (23) died

In this study we performed a screening of 1543 (58.9%) people who visited the differentiated triage for COVID-19, in Hospital I Florencia de Mora. We found that 75 out of 100 patients screened had COVID-19, a result similar to 70.07% (192) reported in the study by Villagrán-Olivas K (Mexico)(14), and greater than 22.66% (349) by Vila-Córcoles A. (Spain)(15). Both studies opted for the molecular test for the screening since they were sensitive and specific, as well as because they had no cross reactivity with respiratory viruses (16). However, Villagrán-Olivas K(14) used a population of 242 suspected cases, while Vila-Córcoles A(15), despite included a population of 79 071 patients, only screened 2% (1547).

However, our country opted to diagnose with rapid serologic tests that are economical, easy and simple to use (16), these detect IgM and IgG antibodies, present in up to 40% in the first week from the start of symptoms and reach up to 100% by day 15 (17). Despite that Sánchez C (Lima-Perú) (18) used the same diagnostic test, he included health personnel in his study population, and reported 25.6% (1112). This difference may occur since the population studied was more exposed, unlike our study, in which we opted to wait for isolation time for screening, which would allow for more confirmed cases to be presented.

With regard to months with greater reported cases, these were June and July with 29.4% (340) and 37.2% (432). These results coincide with the months of greater positivity in the department of La Libertad (19).

Among the epidemiological characteristics, the most frequent sex was masculine with 57.5% (664). This result is consistent with the reports by Villagrán-Olivas K (Mexico)14 with 59.38% (114), Ferrer J. (Cuba) with 52.7(71)(20) in hospitalized patients, and Llaro-Sánchez M(Lima-Perú) con 69.57 % (16)(21) in deceased patients. However, they differ with what was found by Vila-Córcoles A. (Spain)(15), Sánchez C. (Lima-Peru)(18) and Guzmán-Del Giudice O. (Lima-Peru)(22), who found that the feminine sex was the most frequent with 59% (206) ,71.7% (797), and 52% (13), respectively. This is because men are more predisposed to contracting COVID-19 due to their greatest habit to tobacco, concomitant diseases (23,24), and exposure to risk determinants, however, these results are not conclusive (23).

The most frequent age group were adults, with 77.9% (900). These findings coincide with Villagrán-Olivas K (Mexico)(14), Sánchez C (Lima-Peru)(18) and Guzmán-Del Giudice O(Lima-Peru)(22), while studies with deceased patients such as Llaro-Sánchez M(Lima-Peru)(21) and Escobar G(Lima-Peru)(25) the frequent age group were older adults. This difference is due because older adults have a high fatality rate due to their immune system deficit, associated to concomitant diseases, which would justify the frequency of studies with deceased patients (26), while in young adults are more immersed in the labor and social sector, which justifies their frequency in our study.(14)

Within the clinical profile, the most frequent comorbidity was hypertension with 6.9% (80). This coincides with Vila-Córcoles A. (Spain)(15) and Escobar G. (Lima-Peru)(25); while it differs from that reported by Villagrán-Olivas K (Mexico)(14) and Sánchez C (Lima-Peru)(18), where the most frequent comorbidity was obesity. This is because hypertensive patients consume medications such as ACE inhibitors and ARA which increase the levels of ACE2, receptors also found in the heart and blood vessels, which would facilitate the entry of virus into cells (12).

In our study, obesity was the second most frequent comorbidity with 3.7% (43), unlike 33.3% (64) referred in the work by Villagrán-Olivas K., who carried out the study in Mexico, a co9untry where obesity is found among the first places in the world (14), while Sánchez C. carried out their study with health personnel, who due to their routine they had no healthy habits, which is why obesity is present among them.

Among the symptoms, the most frequent were cough with 62.9% (726), odynophagia 55.7% (643), and general malaise 48.4% (559). This result differed from Villagrán-Olivas K. (Mexico)(14) and Guzmán-Del Giudice O. (Lima-Peru)(23), who reported fever and cough as the most frequent symptoms. This is because they included hospitalized patients in their sample. Likewise, it partially coincides with the review by Ferrer J. (Cuba)(20), whose study reported cough and fever in patients of all ages, as in this research.

We must mention the insufficient supply of molecular tests as a study limitation, which could have conditioned a sub registry of positive cases of COVID-19 in the 2622 patients who were screened in the differentiated triage. Likewise, the follow-up of some patients was difficult because they did not answer the telephone or because they were hospitalized.


To conclude, we must point out that 75 out of 100 screened patients in our research had SARS-CoV-2, with predominance of the masculine sex, age group 27-59 years, hypertension as comorbidity, and cough and odynophagia as the most frequent symptoms.
