Abstract Diagnostics for COVID-19 detection are limited in many settings. Syndromic surveillance is often the only means to identify cases but lacks specificity. Rapid antigen testing inexpensive and easy-to-deploy can lack sensitivity. We examine how combining these approaches improve guiding interventions low-income communities Dhaka, Bangladesh. Rapid-antigen-testing with PCR validation was performed on 1172 symptomatically-identified individuals their homes. Statistical models were...

Objective To evaluate the diagnostic performance and feasibility of rapid antigen testing for SARS-CoV-2 detection in low-income communities. Design We conducted a cross-sectional community-based accuracy study. Community health workers, who were trained supervised by medical technicians, performed tests on symptomatic individuals, up to two additional household members their households results calibrated against gold standard RT-PCR. Setting Low-income communities Dhaka, Bangladesh....

This paper introduces an Optical Code Division multiplexing (OCDMA) system using two code keying encryptions. In this proposed OCDMA is designed Semiconductor optical amplifiers (SOAs) which has nonlinear character and can implementor different logic functions. SOA based 2 × 1 Codeword Multiplexer (CMUX) to multiplex the user data a DE (CDEMUX) demodulate data. Then multiple access provided WDM design whole system. Transmission distance of 70 km achieved with acceptable bit error rate Q...

Background: Diagnostics for COVID-19 detection are limited in many settings. Syndromic surveillance is often the only means to identify cases, despite lack of specificity and asymptomatic cases. Rapid antigen testing inexpensive easy-to-deploy but concerns remain about sensitivity. We examine how combining these approaches can improve guiding interventions.Methods: Community-based volunteers were trained syndromically assess potential cases low-income communities Dhaka, Bangladesh. tests PCR...
