3 body parts that are most prone to an infection

Pathogens exist on every possible surface of this world. They even exist on the human body invisible to the naked eye. Factually, not all pathogens are bad, and our body’s immune system can ward off most of these bacteria. However, some microorganisms can still manage to invade our bodies and can cause severe infections and there are certain body parts that are more prone to infectious bacteria than the others.

Oral/ mouth cavity

One of the most overlooked body parts that is vulnerable to diseases is the mouth cavity. Cavities and tooth decay are one of the most frequently recurring health issues around the world. They are especially prevalent in children, teenagers, and the elderly. Cavities, however, can affect anyone who has teeth, including infants, as per Mayo Clinic. A good oral hygiene and dental care routine is a must to keep bacterial infestation away.


Most of us, at some point in our lives, have had an ear infection. Ear infections are another common recurrence in our daily lives. These are often regarded as a childhood disease, however, they are not that uncommon in adults or even teenagers. According to PhotoniCare:

Typically, for an adult ear infection, people with a weakened immune system or inflammation in the structures of the ear are more at risk. Adults with diabetes and/or chronic skin conditions (like eczema or psoriasis) also may be more prone to adult ear infections than most.

It is also advised by microbiologist Matthew Lee:

You should never stick your fingers deep inside your ears. The skin that lines the ear canal is very thin and subject to micro-tears.


Our skin makes up almost 15% of our body weight and is one of the first receptors to sensation. Although very strong, it is, however, not impenetrable. Any sort of cut or injury that results in abrasion of the skin makes it instantly vulnerable to all sorts of microbes present in the surroundings. It doesn’t take much time for an infection to flare up if treated carelessly. Diseases like cellulitis and folliculitis are a few examples of skin infections.
