As a parent, it can be challenging to determine whether your child is experiencing the common cold or if they’re dealing with seasonal allergies. Both conditions share many similar symptoms, such as a runny nose, sore throat, and nasal congestion, but there are key differences that can help you tell the difference. Understanding these differences is important for knowing how to treat your child’s symptoms and when to seek medical advice. In this blog, we’ll walk you through how to tell if your child has allergies or just a cold by examining allergy vs cold symptoms, and what to do to help them feel better.
Common Cold Symptoms
The common cold is an upper respiratory tract infection caused by a virus. Cold symptoms typically appear gradually and may include a sore scratchy throat, runny nose, stuffy nose, cough, mild body aches, and sometimes a headache. You might also notice cold weakness and a general sense of being unwell. Colds are usually self-limiting, meaning they improve on their own within a few days to a week. Cold symptoms can also sometimes come with a fever, but rarely (especially in children over 2 years old).
Key cold symptoms:
- Sore scratchy throat
- Runny nose or stuffy nose
- Mild body aches
- Cough
- Rarely fever
- Cold weakness
The symptoms of a cold can start with a sore throat, followed by congestion, coughing, and sometimes watery eyes. Cold symptoms can also be accompanied by a slight fever in some cases, but this is not typical. If your child’s cold symptoms linger for more than a week or worsen over time, it could indicate another condition, and it may be time to consult a doctor.
Allergy Symptoms
Seasonal allergies, also known as hay fever, are caused by allergic reactions to substances like pollen, pet dander, dust mites, and animal dander. These allergens trigger your child’s immune system to overreact, leading to allergy symptoms that resemble cold symptoms. However, unlike the common cold, allergy symptoms tend to occur at specific times, often when allergens are at their peak. Seasonal allergies typically flare up during pollen seasons, such as spring or fall when pollen levels are highest.
Key allergy symptoms:
- Itchy eyes
- Runny nose (clear mucus)
- Sneezing
- Sore scratchy throat
- Nasal congestion
- Postnasal drip (mucus draining down the back of the throat)
- Watery eyes
- Nasal allergies (blocked nasal passages)
One of the most noticeable differences between allergies and colds is that allergy symptoms are usually triggered by exposure to allergens, whereas cold symptoms are more random and not tied to a specific time of year. If your child has a sore throat, nasal congestion, and watery eyes that appear in response to pet dander, dust mites, or high pollen levels, these are likely symptoms of seasonal allergies.
How to Tell the Difference
So, how can you tell if your child’s symptoms are allergies or just a cold? Here are a few key points to look for:
- Warning time symptoms occur: Allergy symptoms tend to appear quickly after exposure to allergens like pollen, dust mites, or pet dander, while cold symptoms develop gradually over a few days.
- Duration: Allergy symptoms may persist for weeks as long as your child is exposed to allergens. Cold symptoms usually last no longer than a week and begin to improve after a few days.
- Fever: The common cold is more likely to cause a fever, though it is rare. Allergies typically do not cause fever, and if your child has a fever, it’s likely to be from a viral or bacterial infection like a cold.
- Itchy eyes: Allergies often cause itchy, watery eyes, a symptom that is uncommon with the common cold. If your child is rubbing their eyes frequently, it may be a sign of allergies.
- Nasal discharge: Cold symptoms may be associated with thick, yellow, or green nasal mucus, while allergy symptoms often involve clear, watery mucus. If your child has clear nasal discharge and frequent sneezing, it’s a good indicator of allergies.
- Nasal congestion: Both allergies and cold symptoms can cause nasal congestion, but with allergies, this is often accompanied by sneezing and itchy eyes. Nasal congestion from a cold may worsen over a few days, while nasal congestion from allergies may stay constant.
- Body aches: Body aches are common with cold symptoms but are rare with allergy symptoms. If your child is experiencing body aches, a common cold is more likely the cause.
- Itchy throat: While both conditions can cause a sore throat, an itchy or scratchy throat is more likely to be related to allergies, especially if accompanied by sneezing and watery eyes.
Treatment Options
The treatment for your child’s symptoms will depend on whether they’re dealing with a cold or allergies.
If it’s a cold: The best treatment for a cold is time. Supportive care includes pain relievers like acetaminophen or ibuprofen to reduce discomfort, saline solution or nasal spray to help clear congestion, and plenty of fluids to keep your child hydrated. You can also use a humidifier in their room to ease congestion, or consider warm liquids like soup or tea to soothe their sore throat.
If it’s allergies: If you suspect that your child’s symptoms are caused by allergies, allergy medications may help. Antihistamines like Benadryl or Claritin can relieve symptoms like sneezing, runny nose, and itchy eyes. Nasal sprays can also help with nasal congestion. If your child is dealing with specific allergens like pollen or pet dander, try to minimize their exposure by keeping windows closed during pollen seasons or using allergen-reducing bedding. If their symptoms are persistent or severe, consulting a pediatrician may be necessary to discuss other treatment options like allergy testing or immunotherapy.
When to Seek Medical Care
If your child’s symptoms persist for more than a week or worsen over time, it’s important to seek medical care. Additionally, if your child develops a fever over 101°F, has difficulty breathing, or seems excessively fatigued, these could be signs of a bacterial infection or other health condition that requires professional attention. Your pediatrician can help you determine whether your child’s symptoms are due to a common cold, seasonal allergies, or another condition.
Final Thoughts
Determining whether your child is experiencing allergy symptoms or common cold symptoms can be challenging, especially since they share many of the same signs. However, by carefully observing the timing, duration, and nature of their symptoms, you can tell the difference between allergies and a cold. If you ever feel unsure, it’s always a good idea to reach out to your pediatrician for guidance.
Whether your child has seasonal allergies or a cold, taking steps to manage their symptoms—such as using pain relievers for cold symptoms or antihistamines for allergy symptoms—can help them feel more comfortable while they recover. And remember, keeping your child’s immune system strong through healthy habits and the flu vaccine can help them avoid getting sick during cold and allergy season.
