TLDR
In this article, a survey was conducted to quantify the seroprevalence of SARS-CoV-2 among police officers in Italy and identify its correlates, and the overall seropresceptibility was 4.8% (95% CI: 4.4-5.3%).Abstract:
Certain professional categories are at a high occupational exposure to COVID-19. The aim of this survey was to quantify the seroprevalence of SARS-CoV-2 among police officers in Italy and identify its correlates. In this cross-sectional study, a nationally representative sample of State police employees was tested for IgG and IgM before the start of the National vaccination campaign. A total of 10,535 subjects (approximately 10% of the total workforce) participated in the study. The overall seroprevalence was 4.8% (95% CI: 4.4-5.3%). However, seropositivity was unevenly distributed across the country with a clear (p < 0.001) North-South gradient. In particular, the seroprevalence was 5.6 times higher in northern regions than in southern regions (9.0% vs. 1.6%). Most (71.2%) seropositive subjects reported having no recent symptoms potentially attributable to SARS-CoV-2 infection. Previous dysosmia, dysgeusia, and influenza-like illness symptoms were positive predictors of being seropositive. However, the prognostic value of dysosmia depended (p < 0.05) on both sex and prior influenza-like illness. The baseline seroprevalence of SARS-CoV-2 in police employees is considerable. A significant risk of occupational exposure, frequent asymptomatic cases and the progressive waning of neutralizing antibodies suggest that the police workers should be considered among the job categories prioritized for the booster COVID-19 vaccine dose.read more

TL;DR: Overall subgroups seroprevalence increased compared to the first wave data but the trends agreed between the first and subsequent waves, except for an increase in the younger age group and in the sector in direct contact with customers.

TL;DR: Serosurveillance results after a vaccination campaign are demonstrated for COVID‐19 of police officers, and it is shown that vaccination increases the likelihood of seroprevalence in this cohort.

TL;DR: Otolaryngologists should be mindful of the symptom of anosmia in outpatients so as not to delay the diagnosis of CO VID-19, and the pathogenic mechanism of olfactory dysfunction and its clinical characteristics in patients with COVID-19 remains unclear.

TL;DR: Warm and wet climates seem to reduce the spread of COVID-19, however, these variables alone could not explain most of the variability in disease transmission and countries most affected by the disease should focus on health policies, even with climates less favorable to the virus.

TL;DR: In this paper, the authors search PubMed, Embase, Web of Science, and World Health Organization Global Research Database on COVID-19 between January 1, 2020 and April 2, 2021 to identify studies that reported silent infections at the time of testing.

TL;DR: The mortality rate is used as the main indicator to evaluate the extent of underreporting and underdetection of COVID-19 cases and indicates that countries like France, Italy, the United States, Iran and Spain have extremely high numbers of undetected and underreported cases.
