Nonetheless, have been our method for use during winter months, extra steps would be needed to account for concomitant non-influenza seasonal pathogens.
In addition, our assumption that changes in well being care–seeking habits are comparable between delicate ILI and non-ILI situation could also be incorrect. Although this assumption was supported by New York City emergency department surveillance data, it’s attainable that differential health care in search of can be present in different … Read More
