What is the difference between cold flu and allergies
Cold, Flu, or Allergy?
Know the Difference for Best Treatment
You’re feeling beautiful lousy. You’ve got sniffles, sneezing, and a sore throat. Is it a freezing, flu, or allergies? It can be hard to tell them apart because they share so numerous symptoms. But understanding the differences will assist you select the best treatment.
“If you know what you own, you won’t take medications that you don’t need, that aren’t effective, or that might even make your symptoms worse,” says NIH’s Dr.
Teresa Hauguel, an expert on infectious diseases that affect breathing.
Cold, flu, and allergy every affect your respiratory systemThe body parts that assist you breathe, including your nose, throat, and lungs., which can make it hard to breathe. Each condition has key symptoms that set them apart.
Colds and flu are caused by diverse viruses.
“As a law of thumb, the symptoms associated with the flu are more severe,” says Hauguel. Both illnesses can lead to a runny, stuffy nose; congestion; cough; and sore throat. But the flu can also cause high fever that lasts for 3-4 days, along with a headache, fatigue, and general aches and pain. These symptoms are less common when you own a cold.
“Allergies are a little diverse, because they aren’t caused by a virus,” Hauguel explains. “Instead, it’s your body’s immune systemProtects your body from invading germs and other microscopic threats.
reacting to a trigger, or allergen, which is something you’re allergic to.” If you own allergies and breathe in things love pollen or pet dander, the immune cells in your nose and airways may overreact to these harmless substances. Your delicate respiratory tissues may then swell, and your nose may become stuffed up or runny.
“Allergies can also cause itchy, watery eyes, which you don’t normally own with a freezing or flu,” Hauguel adds.
Allergy symptoms generally final as endless as you’re exposed to the allergen, which may be about 6 weeks during pollen seasons in the spring, summer, or drop.
Colds and flu rarely final beyond 2 weeks.
Most people with a freezing or flu recover on their own without medical care. But check with a health care provider if symptoms final beyond 10 days or if symptoms aren’t relieved by over-the-counter medicines. For more about when to see a doctor, go to CDC’s Flu Page.
To treat colds or flu, get plenty of relax and drink lots of fluids. If you own the flu, pain relievers such as aspirin, acetaminophen, or ibuprofen can reduce fever or aches. Allergies can be treated with antihistamines or decongestants. See the “Wise Choices” box for more details.
Be careful to avoid “drug overlap” when taking medicines that list 2 or more athletic ingredients on the label.
For example, if you take 2 diverse drugs that contain acetaminophen—one for a stuffy nose and the other for headache—you may be getting too much acetaminophen.
“Read medicine labels carefully—the warnings, side effects, dosages. If you own questions, talk to your doctor or pharmacist, especially if you own children who are sick,” Hauguel says. “You don’t desire to overmedicate, and you don’t desire to risk taking a medication that may interact with another.”

How numerous times own you dismissed sniffles as "just a cold," and carried on with a stuffed nose and sinuses assuming that the symptoms would eventually run their course, perhaps a bit more quickly with a few doses of Mom’s homemade chicken soup?
Influenza is another tale. The common freezing eventually fizzles, but the flu may be deadly. Some 200,000 people in the U.S. are hospitalized and 36,000 die each year from flu complications — and that pales in comparison to the flu pandemic of 1918 that claimed between 20 and 100 million lives. The best defense against it: a vaccine. Yet barely 30 percent of 4,000 U.S. adults surveyed said they’d been inoculated this season, despite a record supply of flu shots, according to a new RAND Corp.
survey. (GlaxoSmithKline, which makes flu vaccine, helped pay for the survey.)
So what is the difference between a freezing and the flu – and how can you be certain which one you have?
We asked Jonathan Field, director of the allergy and asthma clinic at N.Y.U. Langone Medical Center/Bellevue Hospital in New York. Following is an edited transcript of our interview with him.
What causes the flu?
How is it diverse from a cold?
The flu is a viral infection caused by the influenza virus, a respiratory virus. The common freezing is also a viral infection caused by the adenovirus or coronavirus and there are numerous, numerous subsets with a lot of variability. That’s why it’s said there’s no cure for the common freezing [and] there’s no genuine vaccine. The flu is known to be from influenza and is preventable with vaccination.
Colds tend to produce runny nose, congestion, sore throat. Influenza is more pronounced in that it infects the lungs, the joints and causes pneumonia, respiratory failure and even death.
It tends to infect the intestinal tract more in kids, with diarrhea and vomiting. Because of the relative immaturity of the gut, they may absorb more virus and that wreaks more havoc on the intestines. Flu causes epidemics and pandemics with the potential for mortality, whereas the common freezing is a nuisance for us.
How can someone who’s feeling ill distinguish between freezing and flu, or an allergy?
Flu typically starts in early November and can go until March. The peak time is now — November to January. Allergy is typical in spring or drop, and freezing more so in winter.
The body can reply in only so numerous ways, but there are things you can use to differentiate.
Allergic symptoms are similar to those of a freezing, but [result from] your immune system responding to something benign. Generally there’s no fever, and there’s an allergic manifestation of itch in the back of the throat or the ears. It’s unlikely with allergy to own body aches. With a freezing, there’s sometimes a low-grade fever.
You can tell the difference by the length and severity of the illness and whether you’ve had a similar experience in the past. Both colds and flu generally final the same seven to 10 days, but flu can go three to four weeks; the flu virus may not still be there, but you own symptoms endless after it’s left.
Allergy can final weeks or months.
Are the treatments for these illnesses different?
For any of these things, if it affects the nose or sinus, just rinsing with saline that gets the mucus and virus out is a first-line defense. It’s not the most pleasant thing to do, but it works extremely well. There are classes of medicines that can assist the flu — Tamiflu and Relenza — antivirals that block viruses’ ability to reproduce and shorten the length and severity of the illness.
But they own to be taken within 48 hours or the cat is proverbially out if the bag [because by then] the virus has done the most of its reproduction. For a freezing or flu, relax and use decongestants and antihistamines, ibuprofen, acetaminophen, chicken soup and fluids.
Zinc supposedly helps the body’s natural defenses work to their natural capacity and decrease the severity and length of a freezing.
Cells need zinc as a catalyst in their protective processes, so if you supply them with zinc, it helps them work more efficiently. You should also withhold iron supplements. Viruses use iron as part of their reproductive cycle, so depriving them of it blocks their dissemination.
The majority of these infections are not bacterial and do not require [nor will they reply to] antibiotics. My law of thumb is that a viral infection should go away in seven to 10 days. If symptoms persist after that, you’d consider if it’s bacteria love Strep or Haemophilus influenzae. Those bacteria cause illnesses that are longer lasting.
Is that treatment approach the same for kids?
In general, the same rules apply: Most children will own six to eight colds a year in their first three years of life, and most are viral. It’s extremely simple to test for strep and for that you should own a [positive] culture [before treating with antibiotics].
Are the strategies for avoiding freezing and flu different?
Avoidance is extremely similar: Strict hand washing, not sharing drinking cups or utensils, and avoiding direct contact with people who are sneezing. As endless as someone has a fever, they own the possibility to transmit infection.
After they’ve had no fever for 24 hours, they’re not infectious.
Centers for Disease Control and Prevention (CDC) now recommends that just about everyone get the flu shot: kids 6 months to 19 years of age, pregnant women, people 50 and up, and people of any age with compromised immune systems. Is the shot beneficial to anyone who gets it?
Unless you own a contraindication, there’s no reason not to get it. Contraindications would include egg allergy (because the vaccine is grown from egg products), any vaccines within a final week or two, and athletic illness at the time of your vaccine.
