Dear Director,

Spain is the country with the most healthcare professionals (HP) affected by the coronavirus 2019 disease (COVID-19) in the world. A report from April 2020 by the European Centre for Disease Prevention and Control notes that 20% of COVID-19 cases in Spain affected this group whereas in Italy, the percentage was 10% and in the United States of America and China, it was 3% and 3.8%, respectively.1 As of May 14, 2020, a total of 236,611 COVID-19 cases had been reported to the National Epidemiological Surveillance Network, of which 39,349 corresponded to HP.2

An observational, prospective study was performed on COVID-19 infections among HP at the Olot Regional Hospital of La Garrotxa (ORHG), a regional hospital in Girona with 136 hospitalization beds in 4 units: units 3 and 4 (U3/U4) with 64 beds for acute patients, and units 1 and 2 (U1/U2) with 72 beds for chronic/community healthcare. U3 was isolated and destined exclusively for the care of COVID-19 patients.

All HP in the hospital were included in the study; only those who did not provide consent were excluded. In a first period (starting on March 11, 2020, when the first case of COVID-19 was diagnosed in the hospital), all HP with symptoms were attended to in the Occupational Health Department in order to diagnose COVID-19. In a second period (starting April 21, 2020, when the last COVID-19 cases were diagnosed in HP), a PCR test was given to HP who did not present with symptoms or who tested negative in the first period.

To diagnose COVID-19, confirmation by means of a positive PCR test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in nasopharyngeal smear samples was required. For the serologic tests, capillary blood samples were used (rapid detection of SARS-CoV-2 antibodies by means of immunochromatography).

The Ethics Committee of the Dr. Josep Trueta University Hospital of Girona approved the study and informed consent was obtained from all participants.

Of a total of 493 HP, 198 (40.1%) consulted with the Occupational Health Department. Of those, 81 (16.4% of the staff) were diagnosed with COVID-19 (Table 1). The majority were women (median age of 43 years) in professional categories in direct contact with patients, particularly nurses and nursing aides, and most (52%) worked in U1/U2 (chronic/community healthcare). The majority of HP consulted for respiratory symptoms, but they also presented with other symptoms (the most frequent were headache and abnormalities in taste or smell). Three HP required hospital admission due to pneumonia, one of which required treatment in the ICU with intubation and mechanical ventilation. Progress was favorable in all cases. The majority had a negative PCR test at 14 days, but in nearly a third, it took 21, 28, or up to 35 days for them to test negative.

Category A (direct contact) includes: porter (2), physical therapist (1), psychologist (1), social worker (1). Category C (no contact and no risk) includes: cafeteria worker (1), kitchen worker (1), hospital lawyer (1).


Includes: Operating Theater (3), Outpatient Clinics (2), Kitchen (2), Rehabilitation (1).


Six skin rashes and one case of macular erythema.


Indication: hydroxychloroquine 400 mg/12 h for one day followed by 200 mg/12 h for 4 more days; azithromycin 500 mg/24 h for one day followed by 250 mg/24 h for 4 more days.


In the context of a clinical trial.

The second period included 412 HP: 117 who had symptoms during the first period but had a negative PCR test and 295 who did not have symptoms. Seventy-seven could not or did not want to participate in the study and the remaining 345 underwent PCR and serologic tests. 100% of the PCR tests were negative and in 28 cases (8.1%), the serologic tests were positive (6 cases for IgM, 11 cases for IgG, and 11 cases for both).

The majority of the HP affected by COVID-19 were women, with a median age of 43 years, a characteristic similar to the few COVID-19 series in HP reported in other countries such as the United States of America,3,4 China,5 and Holland.6 As in these series, the majority presented with respiratory symptoms. Furthermore, a non-negligible proportion of cases also experienced other symptoms, such as headache or digestive abnormalities.4,6 53% of cases reported abnormalities in taste or smell. This percentage is much higher than in other series on HP with COVID-19 (7%–16%),4,6 but is similar to the rate found in a study on the prevalence of these symptoms in mild cases of COVID-19.7

The majority of cases were mild and there was only one ICU admission. Nevertheless, the mortality rate due to COVID-19 in HP reported to date is 49 cases in Spain,2 27 cases in the United States,4 and 23 cases in China.8

In our opinion, many cases of COVID-19 in HP were transmitted within the hospital (nosocomial transmission). Like in other series,9 the majority worked in direct contact with patients (85.2%) and especially in community health units (U1/U2) in which isolation measures were implemented later than those implemented early in U3 (COVID-19 unit) and the Emergency Department, which had fewer transmissions. Therefore, it is probable that the majority of cases in HP were transmitted before stricter isolation measures were implemented.

The time until a PCR test yields a negative result is a limitation to the reincorporation of HP to their jobs. In our study, more than 80% had a negative PCR test at 21 days, which is in line with epidemiological studies that have reported a median of 20 days for a negative result on this test. However, in some cases, it can take much longer.10,11 Seroconversion in our study was higher to that found in the population of Spain (5.0%) and of Girona province (2.5%),12 but much lower than what has been observed in other centers (from 17% to 44%).13,14

In conclusion, 16.4% of HP in our hospital were affected by COVID-19 and 8.1% of those who did not have the disease (at least symptomatically) presented with seroconversion. It is likely that if stricter isolation measures had been implemented early in all units, the number of transmissions would have been lower.
