Viral pathogens are the most common cause of respiratory infection in travelers; causative agents include rhinovirus, respiratory syncytial virus, influenza virus, parainfluenza virus, human metapneumovirus, measles, mumps, adenovirus, and coronavirus.

Clinicians also need to consider novel viral causes of respiratory infection in travelers, including Middle East Respiratory Syndrome (MERS) Coronavirus, avian influenza H5N1 (referred to as H5N1), and avian influenza H7N9 (referred to as H7N9).

Respiratory infection due to viral pathogens may lead to bacterial sinusitis, bronchitis, or pneumonia.

Bacterial pathogens are less common but can include Streptococcus pneumoniae, Mycoplasma pneumoniae, Haemophilus influenzae, and Chlamydophila pneumoniae.

Coxiella burnetii and Legionella pneumophila can also cause outbreaks and sporadic cases of respiratory illness.
