In 2006, an outbreak of Chikungunya virus (CHIKV) of the Asian genotype affected over 200 people in Bagan Panchor village in Malaysia. One year later, a post-outbreak survey was performed to determine attack rate, asymptomatic rate, and post-infection sequelae. Findings were compared with recent CHIKV outbreaks of the Central/East African genotype. A total of 180 residents were interviewed for acute symptoms and post-infection physical quality of life and depressive symptoms. Sera from 72 residents were tested for CHIKV neutralizing antibodies. The estimated attack rate was 55.6%, and 17.5% of infected residents were asymptomatic. Arthralgia was reported up to 3 months after infection, but there were no reports of long-term functional dependence or depression. Symptomatic and seropositive residents were significantly more likely to live in the area with the most dense housing and commercial activities. CHIKV had a high attack rate and considerable clinical impact during the Bagan Panchor outbreak.
OBJECTIVE: This study aimed at evaluating the relationship between severity of visual impairment and depression among elderly Malaysians attending an eye clinic.
METHODS: This was a cross-sectional study. The study population included patients, aged>or=60 years who attended the Eye Clinic in University Malaya Medical Centre. Exposure measurement was based on ophthalmologic examinations by an ophthalmologist. Data on outcome were measured using the Geriatric Depression Scale.
RESULTS: After adjusting for important confounders, severity of visual impairment either having low vision or blind were independent risk factors of depression. The odds of developing depression among elderly with low vision were 2 times more than those with normal vision, and elderly who were blind had almost 5 times the odds to be depressed compared with those having normal vision.
CONCLUSION: Findings from this study suggest a positive relationship between the severity of visual impairment and depression among elderly Malaysians.
