Seroprevalence of Sindbis virus and associated risk factors in northern Sweden

摘要

Mosquito-borne Sindbis virus (SINV) cause disease characterized by rash, fever and arthritis which often leads to long-lasting arthralgia. To determine the seroprevalence of SINV and associated risk factors in northern Sweden, a randomly selected population aged between 25 and 74 years were invited to join the MONICA study. Serum from 1611 samples were analysed for specific IgG antibodies. Overall, 2·9 had IgG against SINV. More men (3·7) than women (2·0) were SINV seropositive (P=0·047) and it was more common in subjects with a lower educational level (P=0·013) and living in small, rural communities (PA
