Most often, upper respiratory infection is 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.
What is a lower respiratory infection? Lower respiratory (tract) infection or LTRI is a generic term for an acute infection of the trachea (windpipe), airways and lungs, which make up the lower respiratory system. LTRIs include bronchitis, croup and pneumonia.
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath , weakness, fever , coughing and fatigue. [3]

Among the isolated Gram-negative organisms, Pseudomonas aeruginosa (n = 71, 35.32%) was the most predominant pathogen, followed by Haemophilus influenzae (n = 68, 33.83%), Klebsiella pneumonia (n = 36, 17.19%), and Escherichia coli (n = 26, 12.94%).
Although viruses, mycoplasma, rickettsiae and fungi can all cause lower respiratory tract infections, bacteria are the dominant pathogens; accounting for a much higher percentage of lower than of upper respiratory tract infections.
2022 ICD-10-CM Diagnosis Code J06: Acute upper respiratory infections of multiple and unspecified sites.
Pneumonia as the Most Common Lower Respiratory Tract Infection.
The number one cause of lower respiratory tract infections are viruses that invade the respiratory tract. Bacteria are the next most common cause. In bronchitis, the most common viruses are influenza (“the flu”) and the rhinovirus (which causes the common cold).
Differences Between the Most Common Respiratory Infections. Four of the most common types of respiratory infections are COVID-19, the flu, pneumococcal disease, and colds.
Bacterial infections are caused by bacteria, while viral infections are caused by viruses....Bacterial InfectionsSymptoms persist longer than the expected 10-14 days a virus tends to last.Fever is higher than one might typically expect from a virus.Fever gets worse a few days into the illness rather than improving.
Respiratory infections such as COVID-19 start in the upper respiratory tract and, in serious cases, can move into the lower respiratory tract. Respiratory infections are among the most common diseases that affect humans.

J10. 1 Influenza with other respiratory manifestations, seasonal influenza virus identified. Influenzal: acute upper respiratory infection.
ICD-9 Code Transition: 780.79 Code R53. 83 is the diagnosis code used for Other Fatigue. It is a condition marked by drowsiness and an unusual lack of energy and mental alertness. It can be caused by many things, including illness, injury, or drugs.
