Respiratory and Blood Infections

Lower respiratory tract infections vary from upper respiratory tract infections by the area of the respiratory tract they affect. While lower respiratory tract infections include the airways below the larynx, upper respiratory tract infections occur in the structures in the larynx or above. People who have lower respiratory tract infections will circumstance coughing as the primary symptom. People with upper respiratory tract infections will feel these type of symptoms mainly above the neck, such as sneezing, headaches, and sore throats. They may also experience body aches, especially if they have a fever.
