Psoriasis: How Does It Spread?

Psoriasis affects the skin, and individuals who have never seen it may believe it is contagious. However, this is not the case. Psoriasis cannot be passed from one person to another.

Psoriasis: How Does It Spread?

The disease can move from one portion of the body to another.

This is due to alterations in the immune system mechanism that cause psoriasis, not because it spreads from the afflicted skin to other locations.

What Causes Psoriasis?

Psoriasis (see also ‘10 Best Psoriasis Shampoos For Scalp Psoriasis‘) is an immune-mediated illness that causes skin inflammation.

There may be apparent symptoms of inflammation on the skin, such as elevated plaques and scales.

This happens when an overactive immune system accelerates skin cell proliferation.

A month is enough time for normal skin cells to develop and shed.

Skin cells in psoriasis accomplish this in three to four days. Instead of shedding, skin cells accumulate on the skin’s surface. Psoriasis plaques are known to itch, burn, and sting certain people.

Plaques and scales can form everywhere on the body, although they are most frequent on the elbows, knees, and scalp.

Psoriasis-related inflammation can affect different organs and tissues in the body. People who have psoriasis may also have additional health problems.

While scientists are unsure of what causes psoriasis, we do know that the immune system and genetics play important roles in its progression.

We do know one thing: psoriasis is not infectious. Psoriasis cannot be contracted from another individual.

Psoriasis is usually triggered by something, causing symptoms to emerge or worsen. Triggers differ from one individual to the next.

How Does Psoriasis Spread?

Psoriasis can create rash-like red, dry, itchy skin spots. However, psoriasis is more than simply a rash. It’s a skin disorder caused by an immune system malfunction.

Because your skin cells begin to proliferate too quickly, you have elevated areas of skin.

An inflammatory patch may become larger during a psoriasis flare. Another patch might occur somewhere. This indicates that your sickness is in full swing.

Understand that this is natural and frequently temporary. The sickness moves in cycles. It will be active for a few weeks or months, then be silent for another few weeks or months.

Preventing The Spread Of Psoriasis

The greatest way to prevent the spread of psoriasis is to treat flare-ups as promptly and efficiently as possible.

As soon as a psoriasis patch arises, take a holistic approach to your entire well-being.

Psoriasis is more than just a skin condition; it is influenced by stress, food, and overall health, as well as what you put on your skin.

Get adequate sleep, eat a balanced diet, avoid alcohol and cigarettes, manage your stress, and protect your skin from sunburn, wounds, and other injuries to help prevent psoriasis flare-ups.

However, if you are following all of these recommendations and still suffering psoriasis flare-ups, you should consider switching medicines, since this may be a contributing reason. However, you should consult with your doctor first.

Possible Causes For A Psoriasis Flare Up

People who are genetically predisposed to psoriasis may experience their first symptoms after coming into touch with a trigger.

This suggests that a person’s psoriasis is caused by the combination of their genetics, environment, and immune system.

Here are some common triggers that can lead to a psoriasis flare up. 

Drinking Alcohol In Excess

If you drink on a regular basis or have more than two drinks per day, your psoriasis medication may have little or no impact.

Even if you receive therapy, it may not be successful, and you will continue to experience flare-ups.

Alcoholism, or alcohol misuse, has also been linked to psoriasis. Alcoholism is frequently precipitated by depression, a common co-occurring illness with psoriasis.

Alcoholism can cause psoriasis flare-ups as well as other skin diseases such as rosacea and acne.


Smoking increases your chances of developing a variety of problems and diseases. Psoriasis is one of them.

Experts are still investigating why smoking puts you at risk for the skin disorder.

However, many people feel it has something to do with how smoking impacts your immune system and inflammation in your body.

Many studies have revealed that smoking increases your chances of developing psoriasis.

One study discovered that long-term smokers nearly increased their incidence of psoriasis when compared to never smokers.

Another study found that heavy smokers are twice as likely to get psoriasis.

Injury To The Skin

For some people with psoriasis, even the smallest pinprick or mosquito bite can cause plaques to form in unexpected areas. A new psoriasis patch might appear if your skin is injured or irritated.

This is known as the Koebner phenomenon, and it affects one out of every four persons with psoriasis.

Anything that alters your skin on the surface or inside, such as stings, animal bites, burns, wounds, pressure sores, allergic responses, eczema, warts, and sunburn, can cause a Koebner response.


One of the biggest psoriasis causes is stress. A psoriasis flare-up can also be stressful.

This can turn into a vicious cycle if you do not have the tools to break it. Stress management, on the other hand, may help prevent stress from worsening psoriasis.

Weather Conditions

A flare might be caused by the weather. Due to reduced sunshine and humidity, hotter and drier indoor air, as well as stress and illness, cold weather can frequently produce psoriasis flares.

Because of the natural sunshine and greater humidity, warm weather may typically improve psoriasis.


Infections are especially challenging for persons with psoriasis.

The condition is known to be triggered by yeast infections, strep throat, thrush, respiratory infections, and staph infections. When you treat the infection, your flare-ups may subside.


Some medications used to treat high blood pressure, heart disease, arthritis, and mental problems might cause a flare-up of psoriasis.


It is a common misconception that psoriasis is contagious which unfortunately puts those who suffer from it in a stigmatized position.

Even though it is not contagious between people, it can be spread throughout the body of someone who already has it. 

Luckily there are ways that you can control these flare ups which are easy to put into practice – including eating a balanced, healthy diet, avoiding smoking and alcohol, sleeping well, and managing your stress.
