Epidemiology and risk factors related to severity of clinical manifestations of COVID-19 in outpatients: A retrospective study in Haiti.

Background: Haiti's first COVID-19 cases were confirmed on March 18, 2020, and subsequently spread throughout the country. The objective of this study was to describe clinical manifestations of COVID-19 in Haitian outpatients and to identify risk factors for severity of clinical manifestations.

Methods: We conducted a retrospective study of COVID-19 outpatients diagnosed from March 18-August 4, 2020, using demographic, epidemiological, and clinical data reported to the Ministry of Health (MoH).

The where of when: Geographic variation in the timing of recent increases in US county-level heart disease death rates.

Purpose: Within the context of local increases in US heart disease death rates, we estimated when increasing heart disease death rates began by county among adults aged 35-64 years and characterized geographic variation.

Methods: We applied Bayesian spatiotemporal models to vital statistics data to estimate the timing (i.e.

An assessment of infant medication administration and storage practices in selected communities in the Vhembe District of Limpopo Province, South Africa.

Background: Effective infant medication administration and storage is a major public health challenge outlined by the World Health Organization. These challenges may be exacerbated in rural or limited-resource areas.

Aim: The aim of this study was to investigate infant medication administration and storage practices.

Associations of Environmental Conditions and Genetic Markers in Washington State Pacific Oysters.

is a naturally occurring bacterium in estuarine waters and is a major cause of seafood-borne illness. The bacterium has been consistently identified in Pacific Northwest waters and elevated illness rates of vibriosis in Washington State have raised concerns among growers, risk managers, and consumers of Pacific oysters (). In order to better understand pre-harvest variation of in the region, abundance of total and potentially pathogenic strains of the bacterium in a large number of Washington State Pacific oyster samples were compared with environmental conditions at the time of sampling.
