The hoarseness is not contagious - laryngitis is an inflamed voice box. But the virus that usually causes it is.
Per MedlinePlus, the most common form is viral, with allergies and voice overuse as the other causes; the contagious days were mostly before your voice went. Allergy and overuse versions spread nothing. Rest the voice - and avoid whispering, which strains cords more than soft speech - and escalate hoarseness past two weeks.
What to do
Common questions
Is laryngitis contagious?
The lost voice itself, no - laryngitis is inflammation of the voice box, and MedlinePlus notes its most common form is an infection caused by a virus, with allergies, bacterial infection, and voice overuse as the other usual causes. So the contagion answer splits the way it does for most symptom questions: the hoarse voice and sore throat are your own inflamed vocal cords, nothing anyone can catch, but the virus that caused them - usually a cold or flu virus - is contagious, and the days when you were getting sick were the contagious ones. By the time your voice is gone, the peak-spreading window has often passed. Allergy-driven and overuse laryngitis - the singer's or teacher's version - involve no germ at all and spread nothing. The care is the same regardless: rest the voice (speak less, and avoid whispering, which strains cords more than soft speech), hydrate, humidify, and skip smoking. The flags that change it: hoarseness lasting more than two weeks, breathing difficulty, or coughing blood - those get a doctor, since persistent hoarseness occasionally signals something serious on the cords.
