The Centers for Disease Control and Prevention (CDC) announces $5.2 million in new cooperative agreements designed to evaluate the effectiveness of community-level measures that could be used during an influenza pandemic to reduce the spread of infection.
Because developing a vaccine against a pandemic influenza strain could take several months, community prevention strategies that don't involve vaccines or other drugs (also called "non-pharmaceutical interventions") may serve as a first line of defense to help delay or reduce the spread of disease. However, little scientific research currently exists on the effectiveness and potential impact of such strategies. Therefore, these studies are designed to identify and evaluate quickly what kinds of non-pharmaceutical strategies, alone or in combination, may help reduce or contain the spread of pandemic influenza.
"While we can't predict the severity of an influenza pandemic before it begins, our ability to effectively respond will depend on how well communities and states can take steps to reduce spread of disease," said CDC director Julie Gerberding, MD, MPH. "Our challenge now is to determine which community-level measures will work best to limit the spread of infection."
Community prevention strategies are public health measures other than drugs, which are aimed at reducing the spread of disease.Â For pandemic influenza, examples include simple infection control measures such as handwashing, cough etiquette and mask use; social-distancing strategies that involve reducing contact with other people including closing schools or workplaces and canceling large public gatherings; voluntary isolation of cases; and voluntary quarantine of household contacts.Â
