Lots of talk in recent days regarding @CDCgov pan-flu mitigation plans.

Catchy title: "Community Mitigation Guidelines to Prevent Pandemic Influenza — United States, 2017"

Found here 👉cdc.gov/mmwr/volumes/6…

In the following thread, I'm going to summarize their recs.

1/x
@CDCgov The plan discusses nonpharmaceutical interventions (aka NPIs) meant to slow the spread of respiratory viruses like influenza (or #COVID19).

These particular guidelines were crafted after the 2009 H1N1 pandemic and also include 2 supplementary TA guidance docs (online).

2/x
@CDCgov The guidance breaks down into 3 main categories:

1⃣ Personal
2⃣ Community
3⃣ Environmental

3/x
@CDCgov PERSONAL NPIs:

➡️ Everyday: voluntary home isolation of ill persons (i.e. stay home when sick); respiratory etiquette (cover your cough); hand hygiene.

➡️ Pandemic: voluntary home quarantine of exposed household members; use of face masks in community settings when ill.

4/x
@CDCgov To translate, much of these recs are common sense things we were taught by our parents.

If you're sick, stay home (*note - I fully recognize how hard this is for many people without access to paid sick leave*).

Don't cough or sneeze on people.

Wash your hands. A lot.

5/x
@CDCgov In a pandemic, things could get kicked up a notch.

Not only should sick people stay home, but so should close household contacts of sick people (assuming they have a high chance of becoming sick).

6/x
@CDCgov The effectiveness of using face masks is a bit less clear (despite the mad rush we've seen on people buying them up all over the world).

CDC recommends that sick people can consider wearing a mask if they MUST go out in public, or when they're in close contact with others.

7/x
@CDCgov "CDC does not routinely recommend the use of face masks by well persons in the home or other community settings as a means of avoiding infection."

However, high-risk groups (immunosuppressed, pregnant, etc.) could consider using a mask if unable to avoid crowded settings.

8/x
@CDCgov COMMUNITY NPIs

➡️School closures and dismissals: temporary closures and dismissals of child care facilities, K–12 schools, and institutions of higher education.

➡️Social distancing measures: standard measures for schools, workplaces, and mass gatherings.

9/x
@CDCgov To translate: in a pandemic, community leaders may decide to close schools.

This may happen before people are sick or after.

"Preemptive, coordinated dismissals" means closing schools (simultaneously/sequentially in a district) BEFORE there is widespread transmission.

10/x
@CDCgov Conversely, "reactive" school closures/dismissals occur when lots of students/staff are ill and absent OR arriving at school ill and being sent home.

There can also be "selective" school closures/dismissals for high-risk populations (child care facilities, etc.).

11/x
@CDCgov Social distancing measures can mean a whole lot of different things.

The options range from putting kids in smaller classes and having them sit further apart to canceling mass gatherings (and all in between).

Plus all of the common sense personal measures discussed above.

12/x
@CDCgov ENVIRONMENTAL NPIs

➡️Environmental cleaning measures: eliminate viruses from frequently touched surfaces and objects

13/x
@CDCgov (Side note: this has already been a hot topic for #COVID19 thanks to widespread coverage of a study assessing surface survival times for SARS, MERS & other CoVs.

My take: we don't know how long SARS-CoV-2 can live on surfaces or if it's effectively transmitted that way.)

14/x
@CDCgov There is certainly benefit (and no harm) in appropriately cleaning frequently touched surfaces/objects in homes, child care facilities, schools, workplaces, and other areas.

Detergent-based cleaners or disinfectants that have been registered with the @EPA should be used.

15/x
@CDCgov @EPA Again, I encourage you to read the full guidelines: cdc.gov/mmwr/volumes/6…

We will undoubtedly be hearing more about these types of measures in the coming days and weeks, and it's important to understand options for protecting ourselves, our families and our communities.
