Kaur P, Ponniah M, Murhekar MV, Ramachandran V, Ramachandran R, Raju HK, Perumal V, Mishra AC, Gupte MD - Emerging Infect. Dis. (2008)

Bottom Line: We investigated chikungunya outbreaks in South India and observed a high attack rate, particularly among adults and women.Transmission was facilitated by Aedes aegypti mosquitoes in peridomestic water containers, as indicated by a high Breteau index.We recommended vector control measures and health education to promote safe water storage practices.

ABSTRACT
We investigated chikungunya outbreaks in South India and observed a high attack rate, particularly among adults and women. Transmission was facilitated by Aedes aegypti mosquitoes in peridomestic water containers, as indicated by a high Breteau index. We recommended vector control measures and health education to promote safe water storage practices.

Figure 2: Chikungunya cases and presence of Aedes spp. immature mosquitoes, Gowripet, Avadi, Chennai, Tamil Nadu, India, 2006.

Mentions: We conducted a larval survey in 56 houses in Mallela and all 657 households in Avadi. In both settings, water was scarce and residents used a variety of water storage containers, including plastic/earthen pots, plastic drums, and cement cisterns. The mean number of containers per household was 9 in Avadi. The HI and BI were 30% (17/56) and 39% (22/56), respectively, in Mallela. The HI and BI were 23% (148/657) and 35% (228/ 657), respectively, in Avadi. We observed a weak but significant correlation between attack rates by 200-m2 grids and BI (r = 0.37, p = 0.04) (Figure 2).
