Chikungunya is a mosquito-borne infection of humans, and its diffusion has increased worldwide. In 2007 an outbreak occurred in Italy. In this study, the antibody response of 133 patients followed up starting from the acute phase of infection was investigated. Antibody titres were periodically scored up to 1 year since the infection: 82.7% of the IgM antibody disappeared within 12 months, and the IgG response lasted longer than 12 months. Nevertheless, the IgG mean titre was lower in 95.5% of patients at the end of follow-up, thus suggesting a decrease within a relatively short period.

Abstract
Chikungunya is a mosquito-borne infection of humans, and its diffusion has increased worldwide. In 2007 an outbreak occurred in Italy. In this study, the antibody response of 133 patients followed up starting from the acute phase of infection was investigated. Antibody titres were periodically scored up to 1 year since the infection: 82.7% of the IgM antibody disappeared within 12 months, and the IgG response lasted longer than 12 months. Nevertheless, the IgG mean titre was lower in 95.5% of patients at the end of follow-up, thus suggesting a decrease within a relatively short period.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
