Par­a­sitic in­fec­tion trig­ger

Down to Earth - - SCIENCE -

RISE IN sea-level and tem­per­a­ture dur­ing the Holocene pe­riod (which be­gan 11,700 years ago) lead to an in­crease in par­a­sitic in­fec­tions in mol­luscs. This has emerged from a study of mol­lusc fos­sils of the pe­riod. Sim­i­lar changes in sea level and tem­per­a­ture, which are likely in fore­see­able fu­ture, can in­fect mol­luscs again. And this time, the in­fec­tion can spread to hu­mans who eat clams and snails. About 56 mil­lion peo­ple glob­ally suf­fer from food-borne par­a­sitic in­fec­tions. PNAS, De­cem­ber 2014
