Dried-blood spots: a cost-effective field method for the detection of Chikungunya virus circulation in remote areas.

abstract：:Trachoma, caused by Chlamydia trachomatis (Ct), is the leading infectious blinding disease worldwide. Chronic conjunctival inflammation develops in childhood and leads to eyelid scarring and blindness in adulthood. The immune response to Ct provides only partial protection against re-infection, which can be frequent. ...
