Symptoms of Respiratory infection

CLINICAL PRESENTATION

Most respiratory tract infections, especially those of the upper respiratory tract, are mild and not incapacitating. Upper respiratory tract infections often cause rhinorrhea or pharyngitis.

Lower respiratory tract infections, particularly pneumonia, can be more severe. Lower respiratory tract infections are more likely to cause fever, dyspnea, or chest pain than upper respiratory tract infections. Cough is often present in either upper or lower tract infections.

People with influenza commonly have acute onset of fever, myalgia, headache, and cough.

At present, MERS should be considered in travelers who develop fever and pneumonia within 14 days after traveling from countries in or near the Arabian Peninsula or who have close contact with such travelers. Practitioners should be aware that regions associated with MERS may expand or change (www.cdc.gov/coronavirus/MERS/about/index.html).

H5N1 and H7N9 should be considered in patients with new-onset severe acute respiratory illness requiring hospitalization when no alternative etiology has been identified and if the patient has recently (within 10 days) been to a country with recently confirmed human or animal cases of H5N1 (www.cdc.gov/flu/avianflu/h5n1-virus.htm) or H7N9 (www.cdc.gov/flu/avianflu/h7n9-virus.htm) or has had close contact with an ill person who has traveled to these areas in the last 10 days.
