Cold or Seasonal Allergy? How to Tell the Difference

The symptoms of a cold and seasonal allergies are almost identical, causing confusion that makes it difficult to identify the real reason and detect the appropriate treatment for it. So, it is important to understand the nature of both symptoms, their beginning, and duration to differentiate between them more effectively. Both colds and seasonal allergies can cause sneezing, a runny nose, or nasal congestion, but both are caused by different reasons.

In this article, we will try to understand the difference between a cold and seasonal allergies, how to differentiate between them, and what the primary treatment options are for both.

What Are Seasonal Allergies and How Occur?

Seasonal allergies are a condition of allergic rhinitis that occurs when a person’s immune system overreacts to harmless environmental elements.

Seasonal allergies are mainly caused by pollen, followed by molds, fungi, dust mites, and pet dander.

When a person with allergies is exposed to these substances, the body produces antibodies to fight them as if they are harmful, leading to symptoms such as sneezing, a runny or stuffy nose, and itchy, red eyes.

Millions of people around the world face allergic rhinitis to varying degrees. Its symptoms are particularly similar to common cold, but there are a number of characteristics that differentiate them.

How to Know If You Have Seasonal Allergies?

The symptoms of seasonal allergies are normally characterized by:

• A runny or stuffy nose.
• Sneezing.
• Coughing.
• Wheezing while taking a breath.
• Itchy eyes and watery eyes.
• Postnasal drip.
• Eczema in some cases.

Seasonal allergies in children commonly characterized by rubing their noses upwards due to itchy noses, which is normally known as allergic salute.

These allergies commonly occurs at a specific time of the year. For example, allergy to pollen commonly occurs in April, when pollen is spread in the air and on outdoor surfaces.

What Is a Cold?

A cold is one of the most common viral infections that usually occurs during winter. It affects the respiratory system and attacks adults twice or three times a year. Children get colds more often compared to adults because of their low immunity and frequent contact with others.

How does a cold spread?

A cold is easily spread from one person to another through droplets of saliva that are released after coughing or sneezing, or through touching objects that have viruses and then touching the nose, mouth, or eyes.

What Are the Signs of a Cold?

When a virus infects someone, it activates the immune system’s response to fight it. At this time, various signs appear, but not all signs attack every person.

Common signs of a cold include:

• A runny nose,
• Sneezing.
• Coughing.
• A sore throat or hoarse throat.
• A mild fever.
• Body aches.
• Fatigue.
• Nasal congestion.

Why Do Allergy Symptoms Resemble a Cold?

It is difficult to distinguish between allergy symptoms and cold symptoms because they resemble each other. Both allergy symptoms and cold symptoms may present with sneezing and a runny nose.

How to Differentiate Between Allergy and Cold Symptoms?

While there are many similarities between the allergy symptoms and colds, there are some differences.

Fever	Common	Rare
Body aches	Common	Rare
Sore throat	Rare	Common
Skin reactions	None	Sometimes
Time of onset	Common in winter but can occur at any other time	Usually at the same time every year

How Long Do Cold and Allergy Symptoms Last?

The time for which cold and allergy symptoms last can help to differentiate between them. Cold symptoms tend to come on gradually, within a day to three days, and then subside gradually over the next few days. It tends to last for about 3 to 10 days, though some colds may last for a longer time.

Allergy symptoms come on suddenly and last for as long as the cause is present. For example, Spring allergies may last for several weeks, while cold symptoms last for only a few days.

Can Allergies Be Transmitted from One Person to Another?

Allergies are not transmissible from one person to another because they are caused by overactive immune responses, unlike colds, which are caused by viruses.
