Lobar Pneumonia

All or a large part of a pulmonary lobe are affected or involved

Types of Pneumonia

Pneumonia types, Pneumonia vaccine

1. Community Acquired Pneumonia

It is a type of Pneumonia when a patient gets infected outside the Hospital. It might be due to the Pneumonia causing Pneumonia that you came across in home, park or some Public area.

2. Hospital Acquired Pneumonia

It is acquired when a patient is hospitalized and stays there for more than 2 days. Subjects with this type are at greater risk and even maybe fatal. As being hospitalized, people have less immunity and are more prone to bacteria and viruses.

Aspiration Pneumonia

This type is acquired when the subject aspires bacteria into lungs, usually from food, stomach acid or saliva

Ventilator Associated Pneumonia

As the name suggests, it is found in people while the patient is on a mechanical ventilator (breathing machine). Hospitalized patients with ongoing treatment in ICU are already on risk of dying due  to their severe illness. In addition to that, if they acquire VAP, chances are more of dying from secondary processes such as nosocomial infection.

Diagnosis of Pneumonia

It is mostly diagnosed by taking look at chest X-Ray of a patient which will show sign of consolidation. The patient’s breath sound via stethoscope will sound like crackles and if you perform a chest percussion, a dull sounding note will be heard.

Micro-Organism Responsible


Streptococcus pneumoniae, Hemophilus influenzae, Chlamydophiala pneumonie, Mycoplasm Influenza


Rhino viruses, Corona viruses, Influenza, RSV (found in infants)


Candida, Aspergillus, Pneumocystis, Jiroveci


Stercoralis, Toxoplasma gondii

Is Pneumonia contagious?

Yes, Pneumonia can be contagious! But relax, not all types of Pneumonia are contagious. When caused by bacteria and viruses, it can be contagious when disease causing microorganism are inhaled into lungs.

However, Pneumonia caused by fungi are not contagious. Reason is, fungi dwell in soil and hence does not infect when it is airborne and inhaled.

Infants less than 2 years and our Elderly family member should get vaccinated if symptoms are diagnosed. As their immune system is weak, added antibodies protect them to fight pneumonia. 

Commonly there are two types of Pneumonia vaccine that protect from various types of this disease

This vaccine will help the subjects at preventing severe pneumococcal disease. However, this vaccine will not prevent from all the infection but can save a patient from getting hospitalized And become more deadly.

PCV13 (Pneumococcal conjugate vaccine)

Adults who require this vaccine only gets 1 shot however Doctors suggest this vaccine to children from years 2, 4, 6and 12.

 PCV13 protect people from 13 of the most severe types of bacteria that cause serious infection in children and adults.

PPSV23 (Pneumococcal polysaccharide vaccine)

These are given in single shot to the people who need it. Doctors can give multiple shot of PPSV23 if patient condition is more chronic.

This vaccine is strong enough to protect against 23 types of pneumonia bacteria. Neither can prevent every type of pneumonia, but they aid the patient by  working against more than 30 common, severe types.
