Sinus Infection Contagious

Do you know the difference between a chronic and acute sinus infection? These two conditions are followed by different symptoms, but in both cases you will experience some of the typical ones – headache, pain, oversensitivity and swelling around the eyes, cheeks, nose and forehead. Nose will be clogged up with a greenish secrete and you will feel like your face is loaded, getting even worse if you tilt your head forward. The pain can easily spread to your teeth which make them oversensitive to sudden movement and this can be really excruciating.

A human being has four pairs of sinuses which are connected with the nostril hallways with a whole line of holes and interlinks. Sinuses are among most mysterious parts of our bodies. They act as a factory for mucus which protects our noses and throats.

Causes of Sinus Infection

A virus infection of the upper part of your respiratory system is commonly the cause for a sinus infection. Every sinus infection leaves a mark in the sinus cavities as well. The inflammatory secrete and swelling of the mucus can lead towards clogging up of the discharge channels. In most cases a sinus infection starts as a bacterial complication of the previous virus infections of the upper part of your respiratory system, commonly along some allergies. Contrary to the general belief about sinus infection contagious properties – it’s not. At least in realistic conditions, especially the bacteria induced one.

Sinus infections are more common with adults rather than children. Diagnosis is especially difficult in early child’s age because typical symptoms are almost never present with small children.


With an acute sinus infection following symptoms may occur – deterioration of the mobility of mucus inside the nostrils, pus discharging from the nose, nasal accent during speech, headaches and pains focused in the root of the nose, cheekbones and forehead. Temperature doesn’t usually go up, but it can happen. All of these symptoms are gone in about 2-3 weeks. Sometimes the symptoms will go on for longer but in a much lower intensity. Summary of these symptoms indicates to sub-acute sinus infection and if they go on for over three months untreated it can cause chronic sinus infection.


Treatment is done symptomatically and with antibiotics, sometimes even surgically. In most cases a symptomatic treatment is enough. Nose drops are used which can reduce the swelling around the mucus of the nose which ensures better drainage and ventilation of the sinuses

If the symptoms indicate that a pus inflammation is happening, antibiotic therapy is applied. Proper treatment accelerates healing and shortens the length of the condition, preventing any complications from happening as well. Antibiotics are usually applied pre-orally and this kind of treatment can last up to 10 days. If the treatment doesn’t show good results, an endoscopic surgical procedure might be necessary in order for the infection to be completely gone. Diet during treatment can also have an important role in terms of treatment efficiency.
