delta change the trajectory of COVID-19 in the US

2021-07-14 - 2021-07

After weeks of declining case counts, followed by a plateau, the United States is seeing an increase in COVID-19 in many parts of the country again, a CDC official warned this week.

vaccination should be required for all health personnel, groups say

2021-07-14 - 2021-07

Multiple societies representing medical professionals recommended Tuesday that COVID-19 vaccination be required for all health care personnel “as a condition of employment.”

Preventive measures stopped C. auris outbreaks at two California hospitals

2021-07-14 - 2021-07

Two hospitals in California explained how they used preventive measures to successfully stop the spread of Candida auris. Experts summarized the responses at the annual conference of the Association for Professionals in Infection Control and Epidemiology. Related studies were also published in the American Journal of Infection Control.

Fine mapping of Ascaris lumbricoides, Trichuris trichiura and hookworm infections in sub-districts of Makenene in Centre Region of Cameroun

2022-08-18 - 2022-08

Preventive chemotherapy (PC) that remains the main control strategy recommended by the World Health Organization to achieve the elimination of soil-transmitted helminth (STH) infections as a public health problem must be strengthened by identifying the remaining transmission hot-spots for the deployment of appropriate control measures. This study was designed to assess the prevalence and infections intensities of soil-transmitted helminths and perform micro scale mapping in order to identify transmission hot-spots for targeted control operations. Stool samples were collected from 1775 children in ten primary schools of eight sub-districts of Makenene in Cameroon. Kato Katz technique was used to process and examine stool samples to detect the eggs of soil-transmitted nematodes. The prevalence of soil-transmitted helminth species as well as the infection intensities was compared. Data visualizations in forms of maps were made using Quantum geographic information system (QGIS) software. The overall prevalence of soil-transmitted helminth infections was 4.8% with a 95% confidence interval (CI) of 3.8–5.9%: 3.0% (95% CI 2.2–3.9) for Ascaris lumbricoides, 1.4% (95% CI 0.9–2.0) for Trichuris trichiura and 0.8% (95% CI 0.5–1.4) for hookworms. The prevalence of soil-transmitted helminth species differ significantly between schools and sub-districts. The intensity of infections was light (2.4%, 1.1% and 0.8%), moderate (0.4%, 0.1% and 0.1%) and heavy (0.2%, 0.2% and 0%) for A. lumbricoides, T. trichiura and hookworm respectively. The mean intensity of infections was 7255 EPG for A. lumbricoides, 2900 EPG for T. trichiura and 298 EPG for hookworm. Between schools, significant difference was recorded in the means of infection intensities of T. Trichiura and hookworms but not for A. lumbricoides. This difference was also significant for T. Trichiura when comparison were between sex. No significant difference were recorded when the comparison were between age. Fine mapping revealed that children harbouring heavy infections were clustered in the same sub-districts; highlighting the presence of high endemicity sub-districts and hot-spots for the transmission of different soil-transmitted helminth species. This study showed a diversity in the prevalence and transmission of different soil-transmitted helminth species. It also hightlighted the need for micro scale mapping to enable the localisation of high endemicity sub-districts and transmission hot-spot sites where targeted control operations must be deployed to achieve STH elimination.

A framework to assess the effects of genetic risk factors on disability-adjusted life years

2022-09-23 - 2022-09

Using population data on genetics and diseases and estimates of disability-adjusted life years, we generated a framework for estimating the effects of genetic factors on healthy life years, similar to the risk assessment framework for traditional modifiable epidemiological risk factors. This framework will help to inform the development and implementation of genetic-based clinical applications.
