Antibody Response 3 Months after 2 Doses of BNT162b2 mRNA COVID-19 Vaccine in Residents of Long-Term Care Facilities.

Background: Older adults living in long-term care facilities (LTCFs) are at increased risk for severe outcomes from COVID-19 and were identified as a priority group in COVID-19 vaccination strategies. Emerging evidence suggests vaccine effectiveness in LTCF populations, but data about median and long-term durability of immune response after vaccination are still limited.

Objectives: In this study, we assessed the humoral response to BNT162b2 mRNA COVID-19 vaccine 3 months after the second dose, in a cohort of 495 residents aged ≥65 years from 11 LTCF in Granada, Spain.

[COVID-19 and functional dependence: cohort study of an outbreak in a nursing home for elderly.].

Objective: Older people have been severely affected by the COVID-19 pandemic. The aim of this study was to describe the main epidemiological findings of a COVID-19 outbreak occurred in March 2020 at a nursing home for elderly in Granada. Risk factors associated with the spread of the virus in the center were investigated.

Cryptosporidiosis outbreak in a child day-care center caused by an unusual Cryptosporidium hominis subtype.

Introduction: This work describes the genetic characterization of Cryptosporidium and Giardia involved in an outbreak in a nursery school in Granada, Spain, that affected seven children under the age of 4.

Methods: Nucleic acids were extracted from the seven stool samples positive to Cryptosporidium or Giardia by microscopy and/or immunochromatography. The species and subtypes of Cryptosporidium were identified by PCR-RFLP and PCR of the SSUrRNA and gp60 genes, respectively.

[Investigation of an outbreak of acute respiratory illness due to exposure to chlorine gas in a public swimming pool].

A case-control study was designed to investigate a chemical accident that occurred in a swimming-pool in the summer of 2005. The aim was to describe the environmental factors involved in the accident, to assess the effect of chlorine gas on the respiratory system, and to perform a clinical and spirometric follow-up. The following interventions were carried out: environmental inspection, epidemiologic survey (including sociodemographic variables), location at the time of the accident, perception of an abnormal smell, and clinical and spirometric outcomes to assess respiratory function.

[Outbreak of gastroenteritis caused by Norwalk virus at a senior citizens assisted living facility in Granada, Spain].

Background: The outbreaks of acute gastroenteritis caused by a virus are currently one of the health problems having the greatest impact on those living in senior citizen facilities. The objective of this study is that of investigating the causes of the start and contagion of an outbreak of acute gastroenteritis caused by a Norwalk-Like virus.

Method: At a senior citizen living facility with 141 residents and 71 employees exposed, the relations between the disease in question and different independent variables: personal traits, features of location, date of onset of symptoms, clinical pattern of the disease and causal factors (food and drinking water intake).

[Seroprevalence of brucelosis in the workers of a plant of treatment of sanitary wastes].

Background And Objectives: The management of biosanitary (hospital) waste, while being a key issue in the prevention of public health risks, involves professional risks as well. The objective of this study was to analyze the risks of infection and their relation with the various works within a cluster of brucellosis detected in an infectious waste plant.

Subjects And Method: Cross-descriptive study of the total of 24 employees at the waste plant.
