COVID-19 infection among healthcare workers: a cross-sectional study in southwest Iran.

OBJECTIVE: With the novel coronavirus pandemic, the impact on the healthcare system and workers cannot be overlooked. However, studies on the infection status of medical personnel are still lacking. It is imperative to ensure the safety of health-care workers (HCWs) not only to safeguard continuous patient care but also to ensure they do not transmit the virus, therefore evaluation of infection rates in these groups are indicated. METHODS: Demographic and clinical data regarding infected cases among HCWs of Fars, Iran with positive SARS-CoV-2 PCR tests were obtained from 10th March to 17th May 2020. RESULTS: Our data demonstrated a rate of 5.62% (273 out of 4854 cases) infection among HCW, with a mean age of 35 years and a dominance of female cases (146 cases: 53.5%). The majority of infected cases were among nurses (51.3%), while the most case infection rate (CIR) was among physicians (27 positive cases out of 842 performed test (3.2%)). Also, the highest rate of infection was in the emergency rooms (30.6%). Also, 35.5% of the patients were asymptomatic and the most frequent clinical features among symptomatic patients were myalgia (46%) and cough (45.5%). Although 5.5% were admitted to hospitals, there were no reports of ICU admission. Furthermore, 10.3% of the cases reported transmitting the infection to family and friends. Regarding safety precautions, 1.6% didn't wear masks and 18.7% didn't use gloves in work environments. CONCLUSION: HCWs are among the highest groups at risk of infection during the COVID-19 pandemic; therefore, evaluating infection rates and associated features is necessary to improve and adjust protective measures of these vulnerable, yet highly essential group.

High Post-Infection Protection after COVID-19 among Healthcare Workers: A Population-Level Observational Study.

Background: Even though a few years have passed since the coronavirus disease 2019 (COVID-19) outbreak, information regarding certain aspects of the disease, such as post-infection immunity, is still quite limited. This study aimed to evaluate post-infection protection and COVID-19 features among healthcare workers (HCWs), during three successive surges, as well as the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection, reactivation, re-positivity, and severity. Methods: This cross-sectional population-level observational study was conducted from 20 April 2020 to 18 February 2021. The study population included all HCWs in public or private hospitals in Fars Province, Southern Iran. The infection rate was computed as the number of individuals with positive polymerase chain reaction (PCR) tests divided by the total number of person-days at risk. The re-infection was evaluated after 90 days. Results: A total of 30,546 PCR tests were performed among HCWs, of which 13,749 (61.94% of total HCWs) were positive. Considering the applied 90-day threshold, there were 44 (31.2%) cases of reactivation and relapse, and 97 (68.8% of infected and 1.81% of total HCWs) cases of reinfection among 141 (2.64%) diagnosed cases who experienced a second episode of COVID-19. There was no significant difference in symptoms (P=0.65) or the necessity for ICU admission (P=0.25). The estimated protection against repeated infection after a previous SARS-CoV-2 infection was 94.8% (95% CI=93.6-95.7). Conclusion: SARS-CoV-2 re-positivity, relapse, and reinfection were rare in the HCW population. After the first episode of infection, an estimated 94.8% protection against recurring infections was achieved.

Seizure first aid for people with epilepsy: opinions and knowledge of caregivers and healthcare professionals.

OBJECTIVE: We investigated the opinions and knowledge of the caregivers of people with epilepsy (PWE) and the related healthcare professionals (i.e., nurses and physicians) in Iran about first aid measures for helping a person experiencing a seizure. METHODS: In this exploratory and descriptive study, we surveyed the caregivers of all PWE admitted to the epilepsy monitoring unit at Namazi Hospital, Shiraz, Iran, in May 2022. We also surveyed all the nurses at this hospital. A similar survey was distributed in the WhatsApp groups of the neurology, pediatrics, internal medicine, family physician, psychiatry, and neurosurgery physicians working at places affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. RESULTS: In total, 583 nurses, 70 physicians, and 133 caregivers participated in this study. On most questions, more caregivers provided inappropriate responses than nurses and physicians (e.g., not timing the seizure; not loosening the clothes around the neck; not rolling the patient onto the side if unconscious). On two questions, more caregivers provided appropriate responses than nurses and physicians (i.e., not putting something into the mouth; not always calling for emergency medical services). CONCLUSION: While some actions may help prevent or reduce the chance of harmful consequences of epileptic seizures, many caregivers of PWE and healthcare professionals do not apply appropriate measures to help a patient experiencing a seizure. The scientific community should develop standardized seizure first aid training programs for the general public and healthcare professionals alike.
