RTIs – the most common problem dealt with in primary care
Acute respiratory tract infections (RTIs) are the most common acute health problems attended to in primary care.6 Caused by a large range of bacteria and viruses, acute upper respiratory tract infections (URTIs) are a major cause of morbidity, especially in children.7 The risk of acquiring an RTI is 2-3 times higher in children who attend day-care compared to those who are cared for at home.8
Despite most URTIs being self-limiting, they are the most common cause for visits to healthcare practitioners and for the prescription of antibiotics in children. URTIs therefore cause a substantial social and economic burden.9
Since effective antiviral therapies are not available for most URTIs, other therapies are needed to help support defense against respiratory tract infections and to decrease symptom load. Therapies supporting proper immune function could serve this purpose.
