Capacity of the national influenza surveillance system in Afghanistan, a chronic conflict setting

Influenza surveillance is needed to monitor potential public health threats from the emergence of novel influenza viruses. This study assessed the capacity and performance of the national influenza surveillance system in Afghanistan from 2007 to 2014. Data were collected by review of hospital registers and the National Influenza Centre [NIC] database, interviews with influenza focal points at 9 influenza sentinel surveillance sites and the Centre staff, and observation of the sites. Out of 6900 specimens collected, influenza virus was detected in 253 [3.6%], predominantly H1N1 [63%]; most of these cases were detected during the 2009 pandemic. The NIC had the capacity for virus isolation and PCR identification and performed reasonably until 2011 when support of the Naval American Medical Research Unit 3 was withdrawn. The limitations identified in the system indicated the need for: more complete data, improved technical competence and trained human resources, updating of the infrastructure/facilities, and the presence of standard operating procedures throughout surveillance

Prevalence of risk factors for noncommunicable diseases in Jalalabad city, Afghanistan, evaluated using the WHO STEPwise approach

Noncommunicable diseases [NCDs] are a growing public health challenge. This study aimed to estimate the prevalence of common risk factors for NCDs among the adult population an urban setting in the eastern province of Nangarhar, Afghanistan. In a randomized, cluster sample survey of households the WHO STEPwise method was modified and used to collect demographic, behavioural and clinical data from 1200 adults [61% females] in Jalalabad in 2013. Blood samples were collected for biochemical testing. The prevalence of overweight/obesity, diabetes and hypertension were 57.4%, 11.4% and 24.4% respectively. Among respondents, 8.0% reported being current cigarette smokers and 13.7% used mouth snuff; 69.8% and 19.6% had < 3 servings of fruits and of vegetables respectively in a week; and 33.5% and 57.8% reported vigorous and moderate physical activity respectively. Tailored interventions on risk factors of NCDs are needed in urban areas in Afghanistan
