Boisson, B. Irons Caribbean Epidemiology Centre (CAREC), Pan American Health Organization (PAHO/WHO), Port of Spain, Trinidad and Tobago Background: In June 2009, the first cases of pandemic influenza occurred in the English Caribbean, just prior to the WHO declaration of pandemic level 6. Since then the virus has spread rapidly throughout the sub-region. Methods: In response to the pandemic, at the sub-regional level: alerts, updates and guidelines were developed and distributed; a Situation Room was activated with two 24/7 emergency phone lines; a multidisciplinary Flu Team was formed; the laboratory testing algorithm for influenza was revised; there was a rapid increase in testing capacity; specimen collection kits, laboratory supplies and reagents were sent to countries; and prepaid courier accounts were set-up for shipment of specimens. Countries revised and implemented their pandemic influenza plans. Results: As of November 18, 2009, there were 1,334 laboratory cases of pandemic (H1N1), including 298 hospitalized cases and 18 deaths identified in 20 of 21 English and Dutch Caribbean countries [Table 1]. Of the 18 deaths; 10 had underlying medical conditions, 9 were obese and 3 were pregnant. Pandemic (H1N1) is the predominant circulating influenza virus type, with seasonal influenza viruses (H1N1, H3N2 and influenza B) also circulating, but at much lower levels. Most (> 85%) influenza cases had symptoms of upper respiratory tract infections; approximately 20% of cases had gastrointestinal symptoms; and approximately 40% had other symptoms such as body pain, myalgia and/or headache. The age groups most affected by pandemic influenza were those aged 0-14 years and 20-49 years. The least affected age group was those aged >60 years. The second wave of pandemic influenza appears to have peaked in the English and Dutch Caribbean. Conclusion: The Caribbean Community responded well to a rapidly changing pandemic influenza situation. The major lessons learnt during this pandemic were the importance of: continuous communication at all levels; efficient and timely surveillance with collaborative clinical, epidemiological and laboratory input; and adequate intersectoral planning, with evaluation and adaptation to meet the changing needs of the disease situation. With another wave expected early in 2010, countries will need to continue to be adequately prepared to deal with the expected increase in influenza cases.

It was brought by a family coming from the UK. The situation continued static, except for another three cases coming from abroad. Two months later specifically after the return of pilgrims from omra (visit to holy Muslim places in Saudi Arabia); we started to detect clusters of H1N1 within the community with no history of travelling abroad or contact with abroad comer. An increase acute respiratory diseases incidence in Khartoum state hospitals above the base line was also reported. The National Public Health Laboratory conducted a survey aiming to determine the burden of H1N1 virus incidence among Sudanese children with acute respiratory illness attending emergency clinics in four pediatrics hospitals in Khartoum state. Methods: Pre-survey orientation about influenza pandemic and expected bacterial pneumonia was held. Training of personnel in specimen collection and preservation. From 5th to 21st of November 2009, a total of 115 nasopharyngeal swabs were collected from children selected according to the WHO criteria of case definition of influenza-like illness. Specimens were sent to the National Public Health Laboratory for real-time reverse-transcriptase–polymerase-chainreaction confirmatory testing for H1N1. Results: H1N1 was confirmed in 51 patients (44.4%), another 5 patients were flu A (untypable) positive. Male to female ratio 26:25. 4 patients were under one year of age, 10 patients were within the range from 1-5 years and 24 patients above 5 years of age. The signs and symptoms of the disease were mild and rarely required more than 24 hours hospitalization. One case of fatality was reported. Conclusion: H1N1 outbreak (>40%) among Sudanese children have been confirmed with predominance of incidence in school aged children (above 5 years).
