If people around you are suffering from a disease and you are not a healthcare worker, it can be difficult to tell whether it is contagious or not. Infectious and noncommunicable diseases look similar on the surface, but how they spread depends on the particular disease. Alopah recently identified 11 diseases that are not contagious:

 

1, Certain pneumonia

 

Whether or not this lung infection is contagious depends on its cause. There are two types of pneumonia that are not spread through person-to-person contact: fungal pneumonia (spread through the environment) and aspiration pneumonia (which develops when food or fluid is inhaled into the lungs). In contrast, bacterial pneumonia and viral pneumonia (which cause the majority of pneumonia) are indeed contagious.

 

2, psoriasis

 

This skin disease is not associated with microorganisms or bacteria. Psoriasis is an autoimmune disease, which means that the immune system attacks the skin. Because it is not caused by microorganisms, it does not spread from person to person.

 

3, ear infections

 

If bacteria are causing this painful disease, rather than water getting in the ear, the most common culprit is the cold virus. Ear infections are not transmitted from person to person because the inner ear is filled with fluid due to congestion caused by a cold and can be infected by bacteria secondarily. However, since ear infections start with a cold, the disease is contagious if the patient still has cold symptoms.

 

4, rosacea

 

This non-contagious skin condition causes redness of the face, with clearly visible blood vessels and sometimes small pus-filled bumps. Rosacea can also sometimes lead to thickening of the skin on the nose. Although medical experts are not sure what causes this skin condition, they speculate that genetics, abnormal facial blood vessels, and even Helicobacter pylori play a role.

 

5, Chronic bronchitis

 

Much like pneumonia, certain forms of bronchitis are contagious, while others are not: this depends on the cause of the inflammation of the bronchial airways. Acute bronchitis (spread from an infection in the upper respiratory tract to the chest) is usually caused by a virus and is contagious. Hundreds of viruses, as well as some bacteria, can cause bronchitis, and acute bronchitis develops when they enter the mucous membranes through the eyes, nose or mouth.

 

Chronic bronchitis, however, is not contagious and it is usually caused by long-term smoking or exposure to environmental pollutants.

 

noncommunicable diseases

 

6, Lyme disease

 

Lyme disease only develops when a tick attaches itself to the body and sucks blood. This means that it is not spread through human-to-human contact, including casual contact, kissing, or even sex. Pets also cannot transmit the disease to people, although it is possible for them to bring ticks into the home.

 

7, Malaria

 

This potentially fatal infection is not spread from person to person. When mosquitoes bite you, they release the malaria parasite into the bloodstream. Patients can develop fever, flu-like symptoms, gastrointestinal problems and jaundice. However, malaria infects red blood cells, which means that blood transfusions and sharing an infected needle can spread the disease to others.

 

8, Urinary tract infections

 

Although urinary tract infections often occur after sexual intercourse, they are not sexually transmitted diseases or infections. It occurs when bacteria enter the urethra through the anus. Sex increases this transmission, but this occurs through physical contact that contaminates the urethra, not from one infected party to another during sex. Women are more susceptible to urinary tract infections than men because of the close proximity of their reproductive and excretory organs. More importantly, urinary tract infections can occur in a variety of ways, not just through sexual intercourse.

 

9, tetanus

 

Although this disease is terrible, tetanus is not contagious. The bacteria that cause this disease live in the environment, on the soil and on many surfaces, and enter the body through broken skin. Possible ways to contract tetanus are puncture wounds (such as stepping on a nail), wounds contaminated with dirt or fecal particles.

 

10, Cellulitis

 

You do need to take cellulitis seriously because it can lead to life-threatening bacteremia or endocarditis, but you usually don’t have to worry about passing it on to others. That’s because this infection is caused by bacteria that live on the skin and are usually harmless: Streptococcus pyogenes and Staphylococcus aureus are two common culprits. It is only when they penetrate the deeper layers of the skin that they cause problems.

 

11, Legionnaires’ disease

 

Outbreaks of disease are not always caused by infected people or animals. In the case of Legionnaires’ disease, it is the contaminated water source that is the culprit. The disease only develops when a person inhales a mist or droplet of water containing Legionella bacteria. Although this rare form of pneumonia is serious and deadly, not everyone who is exposed to Legionella will get the disease. The susceptible group is middle-aged and older people over the age of 50, especially if they have compromised immune function or chronic illness.
