Spreading Sickness (USA, 2015)

A PSA which aired on TV in the USA, in 2015. A supposed 'earlier version' aired on TV in 2013, but no footage of it has been found. The PSA was also aired with no company name attached to it, so the creator is unknown, alongside the original title of the PSA, making the name of it 'spreading sickness', since that's what the PSA was about.
It was targeted more towards kids, and a younger audience, so they know how to avoid spreading sickness.
The PSA would start out in a children's hospital room, with a kid, doctor, and a worried parent standing in it. The doctor would read out a diagnosis of a cold, and handing over medicine to take. By Monday, the kid is still sick, and the kid assures their parent that they can go to school just fine. 
Getting on the bus, the kid starts to feel a little sick again, letting out a cough when talking to a classmate. Later the same school day, the teacher is teaching about ways to avoid spreading sickness, showing a diagram of ways that sickness can be spread, suggesting the class to cough into their elbow or a tissue, and the class learns. But, later when they go home from school, the classmate and the kid feel sick again. But, when they have to cough, they remember what they learnt. Coughing into their elbow. The PSA would end with them laughing together, and later feeling better. 
"Children don't know everything, so it's better to teach them."
Though, the PSA isn't that realistic since the kids nearly got sick and then better in a day.
