“…The present study shows that a relatively large proportion of SARI specimens were positive for influenza virus (20.5%). This was similar to studies in other parts of the world, including New Zealand from 2006 to 2010 (22.7%) and Thailand from 2004 to 2010 (21%) . This was 4 times the proportion, however, of influenza‐positive SARI patients in Southern Vietnam between 2008 and 2010 (5.1%) .…”

“…While influenza viruses remain a significant burden of SARI cases in Vietnam, this study showed that non‐influenza‐positive specimens were more than twice as prevalent with other respiratory viruses (41.8%). There are only few studies that have investigated non‐influenza respiratory viruses in SARI patients of Vietnam or in the South‐East Asia region . Some studies have examined non‐influenza viruses in select patient populations such as children, refugees, or hospitalized and non‐hospitalized patients with respiratory disease .…”

BackgroundIn 2016, as a component of the Global Health Security Agenda, the Vietnam Ministry of Health expanded its existing influenza sentinel surveillance for severe acute respiratory infections (SARI) to include testing for 7 additional viral respiratory pathogens. This article describes the steps taken to implement expanded SARI surveillance in Vietnam and reports data from 1 year of expanded surveillance.MethodsThe process of expanding the suite of pathogens for routine testing by real‐time reverse transcriptase–polymerase chain reaction (rRT‐PCR) included laboratory trainings, procurement/distribution of reagents, and strengthening and aligning SARI surveillance epidemiology practices at sentinel sites and regional institutes (RI).ResultsSurveillance data showed that of 4003 specimens tested by the RI laboratories, 20.2% (n = 810) were positive for influenza virus. Of the 3193 influenza‐negative specimens, 41.8% (n = 1337) were positive for at least 1 non‐influenza respiratory virus, of which 16.2% (n = 518), 13.4% (n = 428), and 9.6% (n = 308) tested positive for respiratory syncytial virus, rhinovirus, and adenovirus, respectively.ConclusionsThe Government of Vietnam has demonstrated that expanding respiratory viral surveillance by strengthening and building upon an influenza platform is feasible, efficient, and practical.

The 2009 influenza A(H1N1)pdm09 pandemic highlighted the need for improved scientific knowledge to support better pandemic preparedness and seasonal influenza control. The Southern Hemisphere Influenza and Vaccine Effectiveness Research and Surveillance (SHIVERS) project, a 5-year (2012–2016) multiagency and multidisciplinary collaboration, aimed to measure disease burden, epidemiology, aetiology, risk factors, immunology, effectiveness of vaccination and other prevention strategies for influenza and other respiratory infectious diseases of public health importance. Two active, prospective, population-based surveillance systems were established for monitoring influenza and other respiratory pathogens among those hospitalized patients with acute respiratory illness and those enrolled patients seeking consultations at sentinel general practices. In 2015, a sero-epidemiological study will use a sample of patients from the same practices. These data will provide a full picture of the disease burden and risk factors from asymptomatic infections to severe hospitalized disease and deaths and related economic burden. The results during the first 2 years (2012–2013) provided scientific evidence to (a) support a change to NZ's vaccination policy for young children due to high influenza hospitalizations in these children; (b) contribute to the revision of the World Health Organization's case definition for severe acute respiratory illness for global influenza surveillance; and (c) contribute in part to vaccine strain selection using vaccine effectiveness assessment in the prevention of influenza-related consultations and hospitalizations. In summary, SHIVERS provides valuable international platforms for supporting seasonal influenza control and pandemic preparedness, and responding to other emerging/endemic respiratory-related infections.

“…The zoonotic strains of influenza such as influenza A(H5N1) first detected in humans in 1997 in Hong Kong and then reported widespread globally since 2003, A(H7N9) reported in humans since 2013 in China and A(H9N2) reported for decades to be circulating in poultry and recently reported in humans, are strong evidence of these mutational capabilities; [5][6][7][8]. Therefore, influenza surveillance is essential to monitor and rapidly detect the circulation of different influenza viruses and the emergence of genetic changes in these viruses in humans and animals [9]. Information from influenza surveillance is also important in order to identify circulating strains to be included in the biannual vaccine strain selection to ascertain the needs for each region globally [10].…”
