Could Recent Hurricanes Cause Reemergence of Cholera in Puerto Rico?
Baylor College of Medicine, 27 Sept
The emergence of cholera in Haiti in 2010 is a poignant reminder that the Caribbean remains susceptible to outbreaks. Specifically with respect to Puerto Rico, there are several potential concerns. A 1989 study published in Applied and Environmental Microbiology found Vibrio cholerae bacteria in the Mameyes River, a tropical rain forest watershed on the northeastern coast of Puerto Rico. Presumably V. cholerae could be recovered elsewhere on the island, although I'm not aware of studies that differentiate between pathogenic and non-pathogenic strains of the bacterium.

Rapid Antigen Tests for Dengue Virus Serotypes and Zika Virus in Patient Serum
Science Translational Medicine, 27 Sept
The recent Zika virus outbreak demonstrates that cost-effective clinical diagnostics are urgently needed to detect and distinguish viral infections to improve patient care. Unlike dengue virus (DENV), ZIKV infections during pregnancy correlate with severe birth defects, including microcephaly and neurological disorders. Because ZIKV and DENV are related flaviviruses, their homologous proteins and nucleic acids can cause cross-reactions and false-positive results in molecular, antigenic, and serologic diagnostics.
