After hearing all the news of Covid-19 in the news and social media, one would think every other disease out there is just as contagious.
An infectious disease physician and Senior Scholar at the Johns Hopkins Center for Health Security, Amesh Adalja, MD, explains that“there is not a single relationship between the cause of an infection and its contagiousness, as there are bacterial diseases that are contagious and others that are not,” He says the same is true for some of the deadliest viruses in the world .
The bottom line: It’s never a bad idea to take safety precautions. “Overall,” says Dr. Adalja, “being vaccinated and frequent handwashing are good practices regardless.”
Fungal pneumonia, which is contracted from environments, and aspiration pneumonia, when food or liquid carrying the virus is inhaled into the lungs are the two types of pneumonia that can’t be transmitted from person to person.
The American Lung Association states that bacterial and viral pneumonia are contagious and is the common cause of pneumonia.
“The causative microorganism may move between people but may not automatically cause pneumonia,” says Dr. Adalja. “For example, some bacteria may just colonize the nasal passages, while influenza, which can cause pneumonia, may cause bronchitis in another individual.”
An infected person or animal isn’t always the cause of an outbreak. The same can be said for the case of Legionnaires’ disease, as contaminated water supply is the culprit. The disease can only be contracted when a person inhales or consumes mist or water droplets that contain the bacteria called Legionella.
Faucets, showers, whirlpools and ventilation systems of large buildings can expose you to Legionnaires’ disease, according to the National Institutes for Health.
Those over 50 would be at higher risk, even more so if they have a chronic illness or a weakened immune system.
Psoriasis has nothing to do with germs or bacteria, rather it is a skin disorder found in 2 percent of the American population.
“Psoriasis is an autoimmune condition in which the immune system attacks the skin,” explains Dr. Adalja. “It is not caused by a microorganism that can be passed between people.”
Symptoms of Psoriasis are red, itchy patches of skin topped by white or silvery scales often found in areas such as the scalp, knees, and elbows. It is a result of new skin cells being created which accumulate rapidly.
You can’t get ear infections from people but rather from germs that could reside in water that is stuck in your ears.
A Clinical Associate Professor of Medicine at the George Washington University School of Medicine and an internal medicine and primary care doctor in Bethesda, Matthew Mintz, MD, explains“Due to congestion caused by the cold, the inner ear fills up with fluid and can become secondarily infected by bacteria; these stay in the ear and are therefore not contagious.“
“However, since the ear infection started with a cold, if the patient still has cold symptoms, they can still be contagious.”
Rosacea is a skin condition which causes redness, visible blood vessels in the face, and this is sometimes accompanied by small pus-filled bumps. Another symptom though not common, is the thickening of the skin around the nasal area. However, this is not a contagious disease.
You cannot get poison ivy rash just by touching a person having the rash or touching the fluid from a blister.
The only way you catch poison ivy rash is if you touch the plant’s oil called urushiol, or if urushiol gets onto your clothing or the fur of your pets.
If you accidentally brush against poison ivy, the rash normally appears in a straight line. However, the situation turns bad if it gets onto your clothing or onto your pets fur, as the rash could become more irregular and cover a wider area.
These are some of the common diseases that cannot be transmitted to others. I hope this article helps in the sense that knowing these diseases are not contagious will give you some peace of mind, because if you should unfortunately get one of them, you can rest assured there is no chance of you passing it on to anyone!
