As cases of Hoosiers who test positive for the novel coronavirus are confirmed, schools in central Indiana are continuing to keep families updated on prevention measures and future plans.

Most districts had been in contact with families about COVID-19 ahead of the first confirmed case in Indiana on March 6, reassuring them that districts are being vigilant and are in regular contact with local and state health authorities.

Districts also shared a list of advice from the Centers for Disease Control and Prevention with families. Tips include:

Wash hands frequently with soap and water for 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer.

Avoid touching your eyes, nose, or mouth with unwashed hands.

Cover coughs and sneezes with tissues or by coughing into the inside of the elbow. Throw used tissues away in the trash.

Stay away from people who are sick or not feeling well and avoid close contact with others.

Disinfect frequently touched surfaces and objects such as toys and doorknobs.

Stay home if you are sick. Students should stay home until they are fever free for 24 hours.

Seek help from a health professional if you have symptoms
