Infection is the Invasion of Tissues by Pathogens

An infection (संक्रमण) is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Infectious diseases remain a significant global health concern, causing approximately 9.2 million deaths in 2013 (17% of all deaths). The branch of medicine that focuses on infections is referred to as infectious diseases.

Infection Meaning

An infection is a condition in which harmful microorganisms—such as bacteria, viruses, fungi, or parasites—enter the body, multiply, and cause damage to tissues. These microorganisms are called pathogens. Key Points: Infection occurs when pathogens invade the body. They multiply inside the body. They may produce toxins or cause inflammation, leading to illness. Not all infections show symptoms; some may be silent or mild.

Infection Types

Here are the main types of infections, based on the type of microorganism that causes them:

Bacterial Infections

Caused by bacteria. Examples:

• Strep throat

• Tuberculosis

• Urinary tract infections (UTIs)

Viral Infections

Caused by viruses, which invade body cells and multiply. Examples:

• Common cold

• Influenza

• COVID-19

• Hepatitis

Fungal Infections

Caused by fungi such as molds and yeasts. Examples:

• Ringworm

• Athlete’s foot

• Oral thrush

Parasitic Infections

Caused by parasites, which live on or inside the host. Examples:

• Malaria (parasite via mosquito)

• Amoebiasis

• Tapeworm infection

Protozoal Infections

Caused by protozoa, a specific group of parasites. Examples:

• Giardiasis

• Toxoplasmosis

Helminthic Infections

Caused by worms. Examples:

• Roundworms

• Hookworms

• Pinworms

Prion Infections

Caused by abnormal proteins called prions. Rare but serious. Examples:
