TL;DR: During March to early May 2020, most persons in 10 diverse geographic sites in the US had not been infected with SARS-CoV-2 virus, and the estimated number of infections was much greater than the number of reported cases in all sites.

TL;DR: Seroprevalence estimates suggest that for five of six U.S. sites, from late March to early May 2020, >10 times more SARS-CoV-2 infections occurred than the number of reported cases.

Hutchinson,Maria Morales-Betoulle,Inna Krapinunaya,Ardith Gibbons,Cheng-Feng Chiang,Deborah Cannon,John D. Klena,Jeffrey A. Johnson,Sherry Michelle Owen,Barney S. Graham,Kizzmekia S. Corbett,Natalie J. Thornburg +17 more
TL;DR: This study describes optimization and validation of a SARS-CoV-2-specific-enzyme linked immunosorbent assay (ELISA) using the prefusion-stabilized form of the spike protein and examines cross reactivity with immune sera from persons confirmed to have had infections with other coronaviruses.
Journal ArticleDOI
Culex Flavivirus Isolates from Mosquitoes in Guatemala
Maria Morales-Betoulle,M. L. Monzón Pineda,Silvia M. Sosa,Nicholas A. Panella,Celia Cordon-Rosales,Nicholas Komar,Ann M. Powers,Barbara W. Johnson +7 more
TL;DR: Nucleotide sequence comparison of the eight flavivirus RNA-positive pools showed that there was 100% identity among them, and phylogenetic analysis of the NS5 and envelope gene regions indicated that they represent a strain of the recently described CxFV from Japan.
Journal ArticleDOI
Circulation of Different Lineages of Dengue Virus Type 2 in Central America, Their Evolutionary Time-Scale and Selection Pressure Analysis
TL;DR: It is indicated that the most recent common ancestor for Central American DENV-2 of the American/Asian genotype existed about 19 years ago and positive selection is reported in codons of the genes encoding for C, E, NS2A, NS3, and NS5 proteins.
