Full recordShow full item record
AbstractIntroduction: In confined afloat settings, the threat of an acceleration of the Influenza outbreak is substantial, causing high morbidity of the personnel on board, disrupting daily activities, and leading to low crew morale. In this study, H1N1 Influenza outbreak in a Naval Warship and its control measures are described. Materials and Methods: It is a study of 21 clinically suspected cases of H1N1 Influenza. Cases were reported within 3 weeks from a ship company, all of whom were susceptible. They have been described on the basis of demography, clinical features, recent travel history, and history of contact. Results: Mean age of the clinically suspected cases was 26.71 years. Of 21 suspected cases, 14 were found positive for the disease. Nine cases were admitted to the hospital and two developed complications. Attack rate of the disease was 4.83%. Conclusion: In confined afloat settings, prompt public health measures of active case finding, strict isolation, and adherence to hand hygiene, following cough etiquettes and disinfection enhancement, can effectively mitigate the outbreak. Vaccination may not have a role to play if preventive measures are instituted effectively.
