Pneumonia is an infection that inflames your lungs' air sacs (alveoli). The air sacs may fill up with fluid or pus, causing symptoms such as a cough, fever, chills and trouble breathing.

Stages of lung cancer Non-small cell lung cancer has four main stages: Stage 1: Cancer is found in the lung, but it has not spread outside the lung. Stage 2: Cancer is found in the lung and nearby lymph nodes. Stage 3: Cancer is in the lung and lymph nodes in the middle of the chest.

The main types of pneumonia are bacterial, viral, and mycoplasma pneumonia. A cough that produces green, yellow, or bloody mucus is the most common symptom of pneumonia. Other symptoms include fever, shaking chills, shortness of breath, low energy, and extreme tiredness.

The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).

Often, pneumonia begins after an upper respiratory tract infection (an infection of the nose and throat), with symptoms starting after 2 or 3 days of a cold or sore throat. It then moves to the lungs.

Ways you can get pneumonia include: Bacteria and viruses living in your nose, sinuses, or mouth may spread to your lungs. You may breathe some of these germs directly into your lungs. You breathe in (inhale) food, liquids, vomit, or fluids from the mouth into your lungs (aspiration pneumonia)

Stages of Pathogenesis. To cause disease, a pathogen must successfully achieve four steps or stages of pathogenesis: exposure (contact), adhesion (colonization), invasion, and infection.

The first step in diagnosing pneumonia is a physical examination, in which a doctor will check for rapid breathing and a blue or purple tint to the lips, fingernails or hands, which can indicate low levels of blood oxygen.
