Age-specific SARS-CoV-2 infection fatality rates derived from serological data vary with income and income inequality.

The ongoing COVID-19 pandemic has killed at least 1.1 million people in the United States and over 6.7 million globally.

Modeling the efficacy of CRISPR gene drive for snail immunity on schistosomiasis control.

CRISPR gene drives could revolutionize the control of infectious diseases by accelerating the spread of engineered traits that limit parasite transmission in wild populations. Gene drive technology in mollusks has received little attention despite the role of freshwater snails as hosts of parasitic flukes causing 200 million annual cases of schistosomiasis. A successful drive in snails must overcome self-fertilization, a common feature of host snails which could prevents a drive's spread.
