Article Synopsis
- The study aimed to assess how the vaccination status of the initial COVID-19 case (index case) affects the spread of SARS-CoV-2 among their household contacts.
- Researchers conducted an epidemiological study over 18 months, involving 181 index cases and 314 contacts, calculating the secondary attack rate (SAR) of new infections among susceptible contacts.
- Findings indicated that contacts of vaccinated index cases had a significantly lower SAR (34.9%) compared to those of unvaccinated cases (63.2%), suggesting that vaccination reduces the likelihood of virus transmission within households.
Introduction: The intensity of exposure to index cases of tuberculosis [TB] may increase the risk of TB in their contacts. The aim was to determine TB risk factors among contacts of TB index cases.
Methods: A cohort study was carried out in the contacts of pulmonary TB cases registered by the epidemiological surveillance network from 01/01/2019 to 06/30/2021.
When two outbreaks occur in the same institution within a short period of time, an important health and social concern is generated. Two gastroenteritis outbreaks occurring a week apart in the same facility were reported in Lleida, Spain, in 2018. The objective of this study was to describe the clinical, epidemiological and microbiological investigation carried out and to determine the risk factors.

Methods: We carried out an anonymous survey of seasonal fruit workers in the 2021 campaign in Baix Segria region and Lleida city (Spain) on vaccination, knowledge and attitudes about the COVID-19 vaccine.
