Transmission risk for schistosomiasis peaks at higher water temperature
Mar 9 2021
About one billion people worldwide are at risk for schistosomiasis a debilitating disease caused by parasitic worms that live in fresh water and in intermediate snail hosts.
A new study finds that the transmission risk for schistosomiasis peaks when water warms to 21.7 degrees centigrade, and that the most effective interventions should include snail removal measures implemented when the temperature is below that risk threshold.

Proceedings of the National Academy of Sciences published the results, led by Emory University, the University of South Florida and the University of Florida.

Peregrine pair make All Saintsâ Church in Oakham their new home Published: 12:00, 08 March 2021
A pair of peregrine falcons have won the blessing of a church community after making Oakham their new home.
Since October 2020, the pair have been spotted perching and roosting on the stonework, turrets and parapet walls of All Saintsâ Church in Oakham.
Now, the church community is doing what it can to make it their permanent home so the birds remain there to raise their first brood of chicks.
Peregrine falcons at All Saints Church in Oakham
Churches and other tall buildings have ledges reminiscent of the crags, cliffs and quarry faces which peregrines as a species are used to, while the light pollution of urban locations allows a greater opportunity to be able to hunt nocturnally.
