Timing of influenza A(H5N1) in poultry and humans and seasonal influenza activity worldwide, 2004-2013.

Co-circulation of influenza A(H5N1) and seasonal influenza viruses among humans and animals could lead to co-infections, reassortment, and emergence of novel viruses with pandemic potential. We assessed the timing of subtype H5N1 outbreaks among poultry, human H5N1 cases, and human seasonal influenza in 8 countries that reported 97% of all human H5N1 cases and 90% of all poultry H5N1 outbreaks. In these countries, most outbreaks among poultry (7,001/11,331, 62%) and half of human cases (313/625, 50%) occurred during January-March. Human H5N1 cases occurred in 167 (45%) of 372 months during which outbreaks among poultry occurred, compared with 59 (10%) of 574 months that had no outbreaks among poultry. Human H5N1 cases also occurred in 59 (22%) of 267 months during seasonal influenza periods. To reduce risk for co-infection, surveillance and control of H5N1 should be enhanced during January-March, when H5N1 outbreaks typically occur and overlap with seasonal influenza virus circulation.

The role of a fitness intervention on people with serious psychiatric disabilities.

The purpose of this study was to determine the effects a health education and exercise program would have in limiting weight gain and in improving fitness and psychological parameters in adults with mood or psychotic disorders. Thirty volunteers were randomly assigned to the healthy lifestyle group (HL) or a control group. The HL group engaged in exercise for 12 weeks. Pre- and post-exercise testing was conducted to assess body fat, lipid profile, and cardiovascular fitness. Educational seminars were held weekly. The intervention group evidenced greater weight loss than the control group, although not statistically significant. Significant differences were observed in ratings of general health (p < .05) and empowerment (p < .01). Trends suggest that exercise interventions may encourage weight loss, particularly if barriers to full participation can be addressed. Additionally, such interventions may contribute to "perceived" well-being even among those with subclinical participation.
