Background
The declaration of Coronavirus disease 2019 (COVID‐19) as a Public Health Emergency of International Concern (PHEIC) on 30 January 2020 required rapid implementation of early investigations to inform appropriate national and global public health actions.
Methods
The suite of existing pandemic preparedness generic epidemiological early investigation protocols was rapidly adapted for COVID‐19, branded the ‘UNITY studies’ and promoted globally for the implementation of standardized and quality studies. Ten protocols were developed investigating household (HH) transmission, the first few cases (FFX), population seroprevalence (SEROPREV), health facilities transmission (n = 2), vaccine effectiveness (n = 2), pregnancy outcomes and transmission, school transmission, and surface contamination. Implementation was supported by WHO and its partners globally, with emphasis to support building surveillance and research capacities in low‐ and middle‐income countries (LMIC).
Results
WHO generic protocols were rapidly developed and published on the WHO website, 5/10 protocols within the first 3 months of the response. As of 30 June 2021, 172 investigations were implemented by 97 countries, of which 62 (64%) were LMIC. The majority of countries implemented population seroprevalence (71 countries) and first few cases/household transmission (37 countries) studies.
Conclusion
The widespread adoption of UNITY protocols across all WHO regions indicates that they addressed subnational and national needs to support local public health decision‐making to prevent and control the pandemic.
Results indicate that the introduction of enhanced alcohol labels combining standard drink information and national drinking guidelines may be an effective way to improve drinkers' ability to accurately assess alcohol consumption and monitor intake relative to guidelines. Overall support for enhanced labels suggests probable acceptability of introduction at a population level.
The findings from this study suggest that child safety seat legislation has an impact on restraint use in Canada. Despite the increase in rates of child safety seat use in provinces with new legislation and stable rates in provinces with old legislation, use rates remain low. Injury prevention strategies including further surveillance, interventions, and enforcement of restraint use in children are important to decrease motor vehicle related injury and death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
