2007-2008 Influenza (Flu) Season
International Strategic Planning for an Influenza Pandemic. For example, because of the recent successes in developing vaccines of increased antigenicity for the H5N1 strain, we may soon have vaccine candidates available for stockpiling.

Health care delivery systems and managed-care rwport have done little planning and are essentially unprepared to face the expected shortage of key health care workers.
Each subject received 2 intramuscular injections of the vaccine or placebo and was observed for 56 days. For more information about flu and staph infections visit Seasonal Flu and Staph Infection. During the season, flu-associated deaths in children were reported to CDC. It is caused by influenza virus and is easily transmitted, predominantly via the droplet and contact routes and by indirect spread from respiratory secretions on hands etc.
Annual report of the National Influenza Surveillance Scheme,
Coverage for those with chronic medical conditions was provided by nine Member States and ranged from Although the exact mechanisms underlying avian influenza A human pathogenicity remain unclear, preclinical studies in animal models provide insights into the mechanisms of avian influenza A virus infection and transmission from bird to human and, rarely, from human to human.
Although amantadine and rimantadine two other influenza antiviral drugs also are FDA-approved for treatment or prevention of influenza, these two drugs were NOT recommended for use in the United States during the flu season because many recent flu viruses are resistant to these drugs.
To protect vulnerable individuals ifluenza007 reduce transmission, vaccination is also recommended for healthcare workers. In Europe, influenza occurs in regular annual epidemics in the winter season. Sign In or Create an Account. No resistance to oseltamivir was identified among the ifluenza20077 A H3N2 or the influenza B viruses tested.
Thus, a specific antibody titer will have to be used to predict protection on the basis of experience with seasonal influenza, whereby protection correlates with a hemagglutination inhibition titer of 1: This tool will be used to implement early, targeted, and layered community mitigation strategies. Forty-four per cent of notifications occurred in Queensland.
2007-08 U.S. INFLUENZA SEASON SUMMARY*
During the season, 46 deaths in children were reported to CDC. The Cities Mortality Reporting system helps gauge the severity of a flu season compared with other years.
When compared with the previous three seasons, the season was similar in severity to the flu season in terms of the percentage of deaths due to pneumonia and flu, pediatric hospitalization rates, and ifluenz2a007 percentage of visits to outpatient clinics for flu-like illness.
Interim pre-pandemic planning guidance: Children under 6 months old can become very sick from the flu, but they are too young to get a flu vaccine.
For these reasons, even during seasons when there is a less than ideal match, CDC continues to recommend influenza vaccination. This is the first year that influenza mortality in children became a nationally reportable condition. Use of amantadine or rimantidine is not recommended. However, many problems subsist.
Top of Page How well did circulating viruses match the vaccine strains during the season? Centers for Disease Control and Prevention. Clearly, much has been learned in the past year about our preparedness for an influenza pandemic, and much still remains to be done. Your comment will be reviewed and published at the journal’s discretion. New classes of antiviral drugs expected to enhance treatment and containment options are also emerging. The second dose should be given 28 or more days after the first dose.
Top of Page Was the peak of the flu season typical in terms of timing? Most importantly, international cooperation for pandemic preparedness has resulted in strategic surveillance and planning activities around the world. Seasonal influenza is a vaccine-preventable disease and annual influenza vaccination is the most effective way to prevent influenza. The number of weeks at or above region specific baselines ranged from one in the New England region to seven in the West North Central region with the other seven regions reporting between two and four weeks at or above their region-specific baselines.
During the previous three influenza seasons, the peak percentage of patient visits for ARI has ranged from 3. Over time, a growing number of countries lowered the recommended age for adult influenza vaccination. First, there is a need to use the smallest amount of antigen in the vaccine.
The Institute of Medicine reported on the modeling process and its evaluation [ 35 ]. As of June 19,83 deaths associated with laboratory-confirmed influenza infections have occurred among children aged Pediatric hospitalizations associated with laboratory-confirmed influenza infections are monitored in two population-based surveillance networks: Children 6 months to 9 years of age getting a flu shot for the first time will need two doses of vaccine the first year they are vaccinated, with the first dose ideally being given in September.
Sialidase fusion protein as a novel broad-spectrum inhibitor of influenza virus infection. Human-to-human transmission of H5N1 virus infection is inefficient, and most patients with H5N1 virus infection had direct contact with sick or dead poultry.
During the flu season, a small increase in the number of flu viruses resistant to the neuraminidase inhibitor oseltamivir was observed. Because a sufficient amount of vaccine is unlikely to be available during the first wave of infection and because recourse to antiviral agents may be limited by suboptimal existing stocks and distribution logistics, nonpharmacologic community intervention will be key during this period.
The participation rate was high for each survey, with only one or two countries not responding to any given survey. In this study, all formulations were well tolerated and were immunogenic, even after only 1 dose in some individuals. The clinical morbidity of the infection in terms of complications or most affected groups cannot be determined but anecdotal reports indicate this season may have impacted young adults more than is usual. They can change from the time the vaccine is recommended and the beginning of the flu season, or they can even change during a flu season.
High notification rates were reflected in an increase in presentations with influenza-like illness to sentinel general practices and Emergency Departments. In terms of the influenza A H3N2 virus strain selection for the vaccine, in February ofthere were few influenza A H3N2 virus samples available to guide the selection of the H3N2 vaccine component. Also on the increase are vaccination recommendations for hepatic diseases 15 Member States in —08, 27 in — Among specimens collected since October 1, What can be done to protect children from flu-associated illness and death?
