Difference Between Pneumonia and Typhoid (With Table)

Many infectious diseases have a set of common symptoms. Thus with the occurrence of symptoms, it is easy to get confused as to what type of disease is causing the problems. Hence it becomes very important to get a full-body medical check-up from a doctor right when the symptoms start showing.

Pneumonia vs Typhoid

The main difference between Pneumonia and Typhoid is that Pneumonia is a lung infection that affects the lung tissues. It is caused by the different types of bacteria, fungi, protozoa, etc. Typhoid on the other hand is a type of bacterial infection, caused explicitly by salmonella typhi bacteria. The main cause of Typhoid is contaminated food or water.

Pneumonia is a lung infection, which affects the lung tissues. Different types of bacteria cause pneumonia, such as streptococcus pneumonia, mycoplasma pneumonia, Chlamydia pneumonia, etc. other than bacteria, pneumonia can also be caused by different types of fungi and protozoa present in the air or due to regurgitation of the content of the stomach into lungs.

Typhoid is a bacterial infection that is very common in developing countries. The infection is caused by a specific type of bacteria, salmonella Typhi. The disease is commonly caused due to the ingestion of contaminated food or water. The disease is highly transmissible and can easily transmit from person to person.

What is Pneumonia?

Pneumonia is a lung infection that affects the lung tissues. It is a very common infection and is more frequent in cases of young children and the elderly. It affects the lung tissues and gives rise to breathing issues.

There are many causes of pneumonia, but the most common factors are a special group of bacteria. Streptococcus pneumonia, Mycoplasma pneumonia, Chlamydia pneumonia, and Haemophilus influenza are some of the most common pneumonia-causing bacteria.

Along with bacteria, pneumonia is also caused due to different fungi, viruses, and other micro-organisms present in the air.

As we breathe micro-organisms are sucked into the lungs and because of their small size sometimes they get inside the lung tissues.

They infect the lung tissues as they breed and in some severe cases, the damage is irreversible. Damage to the lung tissues gives rise to many severe respiratory problems.

Difficulty in breathing, chest pain, pain while coughing, presence of mucus in cough, wheezing, high-fever are some of the initial symptoms of pneumonia.      

If the infection is not treated properly and quickly it may lead to severe consequences. Antibiotics, either oral or systemic, proper fluid level balance are some of the required initial treatment methods.

In some cases, oxygen therapy may also be recommended if the patient is unable to breathe properly.

What is Typhoid?

Typhoid is a bacterial infection that affects the digestive system. It is a highly transmissible infection and cases are commonly seen during monsoon season.

Typhoid is caused explicitly due to a type of bacteria called Salmonella Typhi. The presence of this type of bacteria in food or water can result in typhoid. Thus consumption of food from unhygienic sources during monsoon is one of the major contributors to typhoid.

Salmonella Typhi affects the digestive system specifically the gastrointestinal tract, which consists of the intestine, liver, and gallbladder.

The initial symptoms of typhoid are high fever, loss of appetite, abdominal pain, and diarrhea. But in some cases, a person affected with typhoid may not show any symptoms.

Thus it becomes very difficult to detect the problem in such asymptomatic cases. When the infection gets more severe, problems such as nose bleeding, painful cough, and abdominal distension and pain are also seen in patients.

Hence, a medical check-up in the initial stage is very important to prevent the disease from getting severe.    

The treatment includes administration of antibiotics and antimicrobials, followed by a very strict diet planned by the doctor. The diet should be fat-free and in fluid form, to help in easy and quick digestion.

Main Differences Between Pneumonia and Typhoid

  1. Pneumonia is a lung infection which affects the lung tissues. Typhoid is a bacterial infection which affects the gastrointestinal tract, liver, gallbladder, etc
  2. Pneumonia is caused by a lot of things, including different types of bacteria, fungi, viruses and other types of micro-organisms. Typhoid on th other hand is caused specifically due the bacteria, Salmonella Typhi.
  3. Symptoms of Pneumonia include high-fever, chest pain, difficulty breathing, painful cough, etc. symptoms of typhoid include abdominal pain, diarrhea, indigestion, vomiting, loss of appetite, fatigue, etc.
  4. For treating Pneumonia, antibiotics, antipyretics, expctorant and analgesics are precribed. For treating Typhoid, different antimicrobials are prescribed. This is follwed by a strict, fat-free diet.
  5. Pneumonia is a very common disease. It affects more than 10 million people every year. Typhoid is relatively rare and there are fewer than 100 thousand cases every year.


Many diseases have common symptoms, which make it difficult to determine what type of disease is affecting someone just by observing the symptoms.

Both Pneumonia and Typhoid are such diseases. In both cases, the infection is accompanied by the same set of initial symptoms. Thus pinpointing the exact cause may become difficult by just noting down the symptoms.

Both the diseases are completely different, with completely different causes and target areas. Thus getting a medical check-up right when the symptoms start to show is very important to prevent the disease from affecting other areas of the body and becoming severe.
