Common cold - Viral respiratory infection

Very low urgency
Very common-

Epidemic infectious disease caused by influenza A and B viruses.

It is transmitted by small droplets of virus-laden saliva and bronchial secretions released into the air when coughing and sneezing.

It presents suddenly with coughing, sneezing, sore throat, weakness, muscle aches, joint pains, headache, abdominal pain, general malaise and fever.

Diagnosis is clinical and treatment is symptomatic.

Antibiotics are not effective as it is a virus.

It is a self-limiting disease and healthy people do not need to be seen. However, it can become complicated in people at risk and it is recommended that these people are vaccinated every winter.
