How to Tell the Difference"},"content":{"rendered":"<p>This time of year, it can be hard to know if your child has symptoms caused by a <a href=\"https:\/\/kpthrivingfamilies.org\/pediatricsblog\/my-child-is-still-coughing\/\" target=\"_blank\" rel=\"noopener\">lingering cold<\/a> or allergies. Is that cough left over from a virus they caught several weeks ago? Or is it the first sign that their allergy season has begun?<\/p>\n<p>Colds are caused by viruses caught after exposure to an ill person. Your body usually fights off the cold with symptoms decreasing after 10-14 days. Colds are most common in fall and winter.<\/p>\n<p>Allergy symptoms occur when a person\u2019s immune system reacts to a trigger or \u201callergen.\u201d <a href=\"https:\/\/www.healthychildren.org\/English\/health-issues\/conditions\/allergies-asthma\/Pages\/Allergy-Causes.aspx?_gl=1*1j6m17i*_ga*MTYxMjYxMTk2OC4xNzc0NTY1MjA2*_ga_FD9D3XZVQQ*czE3NzQ2MzUyNjEkbzIkZzAkdDE3NzQ2MzUyNjEkajYwJGwwJGgw\" target=\"_blank\" rel=\"noopener\">Allergies can occur<\/a> year round if a child is exposed to allergens they are sensitive to. If they are allergic to pollens &#8211; their symptoms will be worst in the spring and maybe summer. Spring allergies are often called \u201chay fever.\u201d Some people are sensitive to indoor allergens like mold, dust mites and pet dander. They will often have worsened symptoms in the winter when spending time indoors with heated air circulating the allergens in the home.<\/p>\n<h2>How do you know if your child has allergies or another cold?<\/h2>\n<p>While colds and seasonal allergies can look similar at first glance, there are some key clues that can help you figure out what\u2019s going on.<\/p>\n<h3>Signs It May Be Seasonal Allergies<\/h3>\n<p>Seasonal allergies (also called \u201chay fever\u201d) are caused by the immune system reacting to things like pollen, grass, or pet dander. Symptoms often follow predictable patterns and exposures.<\/p>\n<h4>Common allergy symptoms include:<\/h4>\n<ul>\n<li><strong>Itching is the hallmark symptom<\/strong><br \/>\nAllergies often cause itchy eyes, nose, throat, and even ears. If your child is constantly rubbing their eyes or nose, allergies are more likely. Some children rub their nose so much they develop a line or slight wrinkle across the middle of it! Colds typically\u00a0<em>do not<\/em>\u00a0cause itching.<\/li>\n<li><strong>Watery eyes and clear nasal drainage<\/strong><br \/>\nAllergy mucus is usually thin and clear. Eye discharge may be watery or sometimes white and stringy. Thick yellow or green mucus is less typical for allergies.<\/li>\n<li><strong>Frequent, repetitive sneezing<\/strong><br \/>\nAllergies often cause rapid bursts of sneezing. Colds can cause sneezing too, but usually less intensely and for fewer days.<\/li>\n<li><strong>Symptoms linked to exposure<\/strong><br \/>\nA big clue: your child may seem perfectly fine indoors but develop symptoms quickly after playing outside or being around triggers like grass or pollen.<\/li>\n<li><strong>Symptoms that linger without improvement<\/strong><br \/>\nAllergies can persist for weeks or even months during a season, if allergen exposure continues.<\/li>\n<\/ul>\n<h3>Signs It May Be a Cold Virus<\/h3>\n<p>Colds are caused by viruses and tend to follow a more defined course.<\/p>\n<h4>Common cold symptoms include:<\/h4>\n<ul>\n<li><strong>Symptoms after exposure to an ill person<\/strong><br \/>\nColds often begin a few days after exposure and start with a sore throat, runny nose, cough, and fatigue. Body aches and low grade fever can also occur. Colds cause coughing \u2013 allergies cause a cough less often. Unless your <a href=\"https:\/\/kpthrivingfamilies.org\/pediatricsblog\/asthma-in-kids\/\" target=\"_blank\" rel=\"noopener\">child has asthma<\/a>, hay fever won\u2019t usually cause a lot of cough.<\/li>\n<li><strong>Fever or general \u201csick\u201d feeling<\/strong><br \/>\nAllergies do\u00a0<em>not<\/em>\u00a0cause fever. If your child has a fever or seems achy a virus is more likely. Both colds and hay fever can cause a child to be tired \u2013 but kids usually seem more energetic and less sick when they have allergy symptoms.<\/li>\n<li><strong>Changing mucus over time<\/strong><br \/>\nIt\u2019s common for cold symptoms to start with clear mucus and then become thicker, sometimes yellow or green, as the illness progresses.<\/li>\n<li><strong>Gradual improvement<\/strong><br \/>\nMost colds last about 7\u201310 days, though cough and congestion can linger a bit longer. You should see at least some improvement over time. On the opposite hand, allergy symptoms can last for months.<\/li>\n<\/ul>\n<h3>When to Check in With Your Pediatrician<\/h3>\n<h4>Reach out to your child\u2019s healthcare provider if your child has:<\/h4>\n<ul>\n<li>Symptoms last longer than 2 weeks without improvement.<\/li>\n<li>Fever for more than a few days.<\/li>\n<li>Symptoms that seem to be worsening.<\/li>\n<li>Persistent cough that disrupts their sleep.<\/li>\n<li>Trouble breathing, wheezing or rapid breathing.<\/li>\n<li>Symptoms or fatigue that affecting daily activities or school.<\/li>\n<li>Asthma that is not being <a href=\"https:\/\/kpthrivingfamilies.org\/pediatricsblog\/asthma-medications-for-children\/\" target=\"_blank\" rel=\"noopener\">controlled by their usual medicines<\/a>.<\/li>\n<li>Any other symptoms that concern you \u2013 it is <em>always<\/em> best to reach out to us for support.<\/li>\n<\/ul>\n<h2>The Bottom Line on How to Tell Allergies From Colds<\/h2>\n<ul>\n<li>Itching, sneezing and clear, watery drainage with environmental triggers?
