Diagnostic Questions for Hypersensitivity Pneumonitis
Your doctor may ask these questions to check for this disease:
- Are you producing phlegm that contains blood?
- Do you have a fever?
- Does your cough worsen after exercise?

Q.
Is Pneumonia Contagious? When You Can Spread It and for How Long
A.
Pneumonia can be contagious depending on the cause: viruses and some bacteria can spread through cough and close contact, while fungal, aspiration, and hypersensitivity pneumonitis are not contagious. Viral pneumonia often becomes contagious 1 to 2 days before symptoms and stays contagious while symptoms last, and bacterial pneumonia is usually contagious until 24 to 48 hours after starting antibiotics; there are several factors to consider, including who is at higher risk and how to prevent spread. For timing nuances, precautions, vaccines, and when to seek urgent care, see the complete details below.

Q.
Parents: When Can My Child Go Back to School After Pneumonia?
A.
Most children can return to school once they are fever-free for at least 24 hours without medicine, are breathing comfortably, have enough energy to get through the day, are eating and drinking, and their cough is manageable often 24 to 48 hours after starting antibiotics if prescribed. A lingering cough can last weeks but is usually okay if fever free and breathing well. There are several factors to consider, including the cause of pneumonia and special situations like very young age, asthma, immune problems, or hospitalization; see below for timing after antibiotics, signs to seek urgent care, and steps to reduce spread.

Q.
Think You’re Not Contagious Anymore? Pneumonia Has a Catch
A.
Pneumonia can be contagious, and there are several factors to consider. Viral and some bacterial pneumonias spread through droplets and may still be transmissible even as you feel better, while aspiration, chemical, or immune related pneumonias are not; antibiotics usually lower bacterial spread within 24 to 48 hours. For how long you might be contagious, when to stay home, who is high risk, the tests doctors use, and urgent warning signs, see the complete guidance below.
