recommendations for use of antiviral medications have a changed, enhanced surveillance for detection of oseltamivir. resistant influenza viruses is ongoing and will enable continued monitoring of changing trends over time. In addition to vaccination and antivirals, other means of decreasing ta spread and impact of influenza include staying home free work or school when ill, avoiding others who are sick, corering the nose or mouth with a tissue when coughing a sneezing, and frequent hand washing. Additional information is available at http://www.cdc.gov/flu/protect habits.htm.
Influenza surveillance reports for the United States ar posted online weekly during October-May and are avail. able at http://www.cdc.gov/flu/weekly/fluactivity.htm Additional information regarding influenza viruses, inf: enza surveillance, the influenza vaccine, and avian intlıenza is available at http://www.cdc.gov/flu.
Influenza A (H1N1) viruses predominated through midJanuary, but influenza A (H3N2) viruses were more frequently identified than influenza A (H1N1) viruses since late January and have predominated overall. The majority of influenza A (H1N1) viruses were characterized as A/Solomon Islands/3/2006, the influenza A (H1N1) component of the 2007–08 influenza vaccine for the Northern Hemisphere. To date, the majority of influenza A (H3N2) and influenza B viruses were characterized as A/Brisbanel 10/2007 and B/Florida/04/2006, respectively, the recommended influenza A (H3N2) and influenza B components of the 2008-09 influenza vaccine for the Northern Hemisphere.
Clinical vaccine effectiveness cannot be accurately predicted using these data. A case-control study to estimate the effectiveness of trivalent inactivated influenza vaccine was conducted this season in Marshfield, Wisconsin. Preliminary results from subjects enrolled during January 21February 8 show an overall vaccine effectiveness of 44%, suggesting that vaccination provided substantial protection against influenza-associated, medically attended illness in the study population, despite the suboptimal vaccine match (3). These preliminary results are similar to previous studies, which have shown that influenza vaccination provides measurable protection against influenza illness and influenza-related complications and death, even when vaccine strains are antigenically distinct from circulating strains (4-7).
As a supplement to influenza vaccination, antiviral drugs have aided in the control and prevention of influenza. Recent studies have identified a considerable protective effect of oseltamivir treatment against complications associated with influenza (8), including death among older adults hospitalized with laboratory-confirmed influenza (9). This season, resistance to the influenza antiviral drug oseltamivir among influenza A (H1N1) viruses (84 (10.2%] of 824 tested) has been detected. All 84 resistant influenza A (H1N1) viruses identified in the United States this season share the same genetic mutation; this mutation is the most common mutation in this subtype that confers resistance to oseltamivir. Increased resistance to oseltamivir among influenza A (H1N1) viruses has been reported from many countries this season (10). No oseltamivir resistance has been detected among influenza A (H3N2) or B viruses currently circulating in the United States. Given the low level of resistance to oseltamivir, the finding of resistance only in some influenza A (H1N1) viruses, and no resistance to zanamivir, these drugs continue to be recommended for the treatment and prophylaxis of influenza (2).

National Infant Immunization Week
April 19–26, 2008 The week of April 19–26, 2008, is National Infant nmunization Week (NIIW) and Vaccination Week in the mericas (VWA). Immunization is one of the most effecve ways to protect infants and children from potentially erious diseases. During the week, hundreds of communies throughout the United States are expected to sponsor ctivities to emphasize the health benefits of timely vacciation and the importance to parents, health-care providrs, and communities of maintaining high vaccination overage. One message stressed during this week will be ne key role of the ongoing relationship among parents and heir children's health-care providers in vaccination prorams. CDC encourages parents to talk to their healthare providers about vaccinations at any time.
The week's activities provide an opportunity to showcase : le success of vaccination in saving the lives and protecting ne health of children. The currently recommended childood vaccination schedule (1) includes vaccines that preent infectious diseases such as measles, polio, whooping pugh, some forms of meningitis and pneumonia, and liver ancer. An analysis of the impact of seven vaccines showed hat they would prevent approximately 33,500 deaths and 4 million illnesses per annual birth cohort (2). NIIW-VWA events held in collaboration with CDC and ate and local health departments will be hosted in Rhode land, Connecticut, and Washington. Events held in colboration with CDC, state and local health departments, ne United States-Mexico Border Health Commission, and ne Pan American Health Organization (PAHO), will be osted in communities along the U.S.-Mexico border, with ick-off events held in El Paso, Texas, and Sunland Park, lew Mexico. In all locations, events will include educaon activities for health-care providers, media briefings, id immunization clinics. VWA, sponsored by PAHO, targets children and other ulnerable and underserved populations who have low vacnation coverage rates, in all countries in the Western hemihere. To support NIIW and VWA events nationwide,
International Course in Applied
Epidemiology CDC and Emory University's Rollins School of Public Health will cosponsor the International Course in Applied Epidemiology, to be held September 22–October 17, 2008, in Atlanta, Georgia. The course is designed for public health professionals from countries other than the United States. It will include presentations and discussions of epidemiologic principles, basic statistical analysis, public health surveillance, field investigations, surveys and sampling, and the epidemiologic aspects of current major public health problems in global health.
Group discussions of epidemiologic case exercises based on field investigations will be held during the course. Participants are encouraged to give a short presentation reviewing some epidemiologic data from their own country. The course also will include computer training using Epi Info (Windows version), a software program for epidemiologists developed at CDC and the World Health Organization.
Prerequisites are familiarity with the vocabulary and principles of basic epidemiology, or completion of CDC's Principles of Epidemiology home-study course or equivalent. Preference will be given to applicants whose work involves priority public health problems in international health. Tuition is charged.
Additional information and applications are available by mail (Emory University, Rollins School of Public Health, Hubert Global Health Dept. (Attn: Pia], 1518 Clifton Rd. NE, Rm. 746, Atlanta, GA 30322); fax (404-727-4590), e-mail (firstname.lastname@example.org), or Internet (http://www. sph.emory.edu/epicourses).
