Covid-19 Response Update: August 28-September 4

Combating Covid-19 Series

This is CSIS’s weekly roundup of major updates on the military and the novel coronavirus since Friday, August 28. It explores what the military has done to combat Covid-19 and how the military has in turn been affected by the virus.

New DoD cases of Covid-19 declined at a slower rate this week, with the 7-day average falling by 10 percent since last Friday to 371 new cases. Deaths rose by eight to 88, an increase of 10 percent from the previous week.

Major Updates:

  • August 31: Thousands of civilian mariners who work for the Navy’s Military Sealift Command have been prevented from leaving their ships unless it was absolutely critical.
  • September 3: The Pentagon has selected several military sites for a Phase III clinical trial of a leading Covid-19 vaccine.

Military Cases of Covid-19

How DoD cases have been trending over time is broken down below, by new cases; total cases; active cases in the DoD; and across the military services.

Methodological note: 1) Monday, Wednesday, and Friday totals are divided across the intervening days and weekends since DoD Covid-19 updates are only released during the work week on a M-W-F basis. 2) Adjustments were made on April 9 and April 15 when new cases where negative. These days were totaled and divided by the previous day to account for the correction. 3) DoD appeared to change the way cases were reported between April 15-Aprilt 16. A resulting spike in cases on April 16 was divided over the two prior days to account for this methodological shift.

This weekly update is made possible by the International Security Program at CSIS.
