"Regardless of whether it's caused by illness or excessive use, laryngitis occurs when your vocal cords become inflamed," explains Dr. Yiu. "This inflammation, or swelling, prevents your vocal cords from vibrating properly — which can lead to hoarseness and, ultimately, voice loss."
Why it happens. In most cases, laryngitis is caused by either: a viral infection – such as a cold or flu, or. damage to your larynx – usually by straining your voice.
It is quite common to experience laryngitis during an upper respiratory infection or other virus. Laryngitis results when the voice box — or larynx — becomes inflamed, causing you to experience difficulty making sound, or hoarseness. Usually, laryngitis resolves once the infection clears up.
“Laryngitis itself is not contagious,” Peña said. “However, the viral upper respiratory infections that cause laryngitis can be.” As long as you don't have any other severe symptoms, you should be able to continue your daily activities while you have laryngitis.
Laryngitis is commonly caused by a viral infection, such as a cold or flu. Bacterial infection may also cause laryngitis, although this is rare. You can also get laryngitis if you strain or overuse your voice by yelling or after long periods of talking, shouting or singing.
You do not have to stop speaking, but use your voice as little as possible. Speak softly but do not whisper; whispering can bother your larynx more than speaking softly. Avoid talking on the telephone or trying to speak loudly. Drink plenty of water to keep your throat moist.
Is laryngitis contagious? Laryngitis is only contagious if an infection caused it. For example, if you have a viral or bacterial infection that caused the condition, it's possible to pass it on to others.
Laryngitis is when your voice box or vocal cords in the throat become irritated or swollen. It usually goes away by itself within 1 to 2 weeks.

Coughing causes the vocal cords to bang together sharply, resulting in increased stress, swelling and irritation of the larynx. The throat then secretes more mucus (which is thick, sticky and hard to move), to try and protect the vocal cords, making the problem worse.
These changes often happen in people who have been very ill with COVID-19 and needed support with breathing (ventilation). This is because the tube that was put into the throat to help with breathing has irritated it. The swallowing or voice changes are likely to get better without any treatment.
Loss of voice can accompany many conditions that affect the throat such as viral sore throat, laryngitis, or mononucleosis. All of these conditions can be associated with fatigue as well.
Conclusion: Previous variants of SARS-CoV-2 infection affected predominantly the lower respiratory tract and were associated with loss of smell and taste in many patients. The Omicron variant seems to affect predominantly the upper airways and cause acute laryngitis without olfactory dysfunction.
Notably, the omicron variant is prone to cause severe laryngitis, resulting in fatal upper airway stenosis.
If your laryngitis is caused by an infection, you're contagious. The most common cause of laryngitis is a viral upper respiratory infection. If your laryngitis is caused by a viral illness, you'll be most contagious for the first three days, but could pass the infection for up to three weeks.
Moisturizing your throat
Throat lozenges, saltwater gargles, and honey added to decaffeinated tea help moisturize the mucous membranes in your throat and relieve the irritating dryness associated with laryngitis.
Most cases of acute laryngitis can be treated with home therapy including: Pain reliever/anti-inflammatory drugs such as ibuprofen, aspirin or naproxen. Warm, hydrating fluids.
Moisture is important to heal inflamed vocal cords. It can also loosen phlegm. Try adding a few drops of vapour rub to your humidifier to soothe discomfort in your throat. Vapour rubs generally contain menthol, which can have a cooling effect on your throat.
If your laryngitis is caused by an infection, you will most likely need a course of oral antibiotics or antifungal therapy before it goes away. This will help minimize and kill the bacteria or fungus growth causing the infection.
The best cure for laryngitis is voice rest. As hard as if may sound, shutting your mouth for at least three days will do wonders for your vocal cords. You should also avoid hard coughing, crying and clearing your throat.
Laryngitis usually isn't a serious problem. With proper treatment, acute (short-lived) laryngitis should go away in no more than 3 weeks. But sometimes, laryngitis lasts longer and becomes chronic. But there are ways to help yourself feel better.
Symptoms and Signs
At times, laryngitis can be an indication of serious laryngeal cancer. The following symptoms definitely warrant a visit to a head, neck, and throat specialist: A sore throat accompanied by a fever. Coughing up yellow or green phlegm (possibly bacterial sinusitis or bronchitis)
Additional signs and symptoms of laryngitis in adults may include dry, sore throat, pain with swallowing, and a feeling of fullness in the throat or neck. If the laryngitis is caused by an infection, the affected person also may have symptoms of fever, swollen lymph nodes (swollen glands).
