The Marshalltown Community School District is adopting new COVID-19 Centers for Disease Control guidelines, which apply to people who have been exposed to a positive COVID-19 case and have no symptoms.

The new guidelines include:

• Anyone exposed to COVID-19, who does not have symptoms and gets tested after the fifth day of quarantine and tests negative, will need to quarantine for seven days from the date of exposure.

• If anyone has been exposed to COVID-19, has no symptoms and chooses not to get tested, they need to quarantine for 10 days from the date of exposure.

• If anyone has been exposed to COVID-19 and has symptoms, they need to continue a 14-day quarantine and get tested.

• Anyone who tests positive at any point, should isolate for 10 days from symptom onset or date of testing, whichever occurred first.

Symptom monitoring and wearing a mask should continue even if quarantine is shortened.

The school district will no longer require staff or students to quarantine for 14 days following out-of-the-country travel, unless known exposure occurred during the trip.
