FIND conducted independent evaluations at the University Hospitals of Geneva (HUG), to verify the limit of detection (LOD) and the clinical performance (as reported by the manufacturers) of the following molecular test kits. The LOD analysis was performed using cultured viral stocks from a clinical ...isolate from Switzerland, and quantified using an E gene standard. The clinical performance analysis was conducted on extracted samples from individuals suspected to have COVID-19 that were tested using an in-house PCR protocol that was optimized based on the Tib Molbiol assay.

Soil-transmitted helminths are a group of intestinal worms that include Ascaris lumbricoides (giant roundworm), Trichuris trichiura (whipworm), and Ancylostoma spp. (A. duodenale, A. ceylanicum) and Necator americanus (hookworms). Despite the clear biological differences among the different species,... their transmission is characterized by the same sequence of events: (i) infected individuals excrete worm eggs through their stool in soil; (ii) under optimal conditions of moisture and temperature the excreted eggs develop into infectious stages; and (iii) finally, infection occurs through oral uptake (Ascaris, Ancylostoma and Trichuris) or skin penetration (Ancylostoma and Necator) of these infectious stages (embryonated eggs and third stage larvae) that reside in the soil and/or in the environment (referring to their common name).

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.
