Upper respiratory tract infections (URTIs) are one of the most common reasons for mild morbidity in adults and children. Common symptoms of RTI include throat pain, pain when swallowing, cold, cough, sneezing, pharyngitis and fever.
It is a known fact that most of the URTIs are caused by VIRUSES, such as adenovirus, rhinovirus, influenza, herpes simplex virus, coronavirus and respiratory simplex virus. In fact, less than 20% of URTIs are caused by bacterial infections that require treatment with antibiotics, while others are mostly of viral origin, wherein antibiotics are ineffective.
One of the main reasons why URTIs have to be addressed early is because they are associated with social costs arising on account of absenteeism from school & work, loss in productivity and use of medical resources. Further, as most of the URTIs are caused by viruses, they are highly contagious and can spread from person to person by inhaling respiratory droplets from coughing or sneezing. The transmission of respiratory infections can also occur by touching the nose or mouth by hand or other objects exposed to the virus.
