What Is The Incubation Period For A Cold

How Does A Cold Spread

Flu Incubation Period — With Herbs that Help!

Colds are spread through the air and on surfaces. When you are sick, coughing, sneezing and even breathing sends the virus into the air around you and onto every surface you touch.

The virus can live on surfaces for several hours, making it possible for others to pick up long after you’ve, say, left a room.

Causes Of The Common Cold

Many different respiratory viruses can cause the common cold, but rhinoviruses are the most common. Rhinoviruses can also trigger asthma attacks and have been linked to sinus and ear infections. Other viruses that can cause colds include respiratory syncytial virus, human parainfluenza viruses, adenovirus, common human coronaviruses, and human metapneumovirus.

How Long Is Croup Contagious

When it comes to croup, the infection is contagious during the incubation period and for about seven to ten days after the symptoms have become visible. It is during this time, that the infected child or the person should avoid contact with other people to help prevent croup from spreading further. The utensils and toys used by the child should also be washed thoroughly after use. Keeping your hands clean before and after taking care of the child are also some necessary precautions that need to be taken care of during this contagious period of croup.

When To Call Your Provider

Occasionally, viral infections can set the stage for more complicated bacterial infections. If you experience any of the following, call your health care provider:

  • High fever
  • Shortness of breath or wheezing
  • Coughing up bloody mucus
  • Coughing so hard that you throw up
  • Feeling worse after 5 to 7 days of symptoms, especially if you have worsening headache, congestion, or sinus pain
  • If you dont start to feel better after 10 days of symptoms

What To Expect With An Upper Respiratory Infection


More than 90 percent of upper respiratory infections are caused by viruses. These infections create different symptoms at each stage. Most colds and flus go away in about a week, although some symptoms can take two or three weeks to go away completely.

Helen Xenos, a One Medical doctor in Chicago, describes the typical progression of the common cold:

  • Day 1: Fatigue, headache, sore or scratchy throat.
  • Day 2: Sore throat worsens, low fever, mild nasal congestion.
  • Day 3: Congestion worsens, sinus and ear pressure become very uncomfortable. It may be difficult to sleep.
  • Day 4: Mucus may turn yellow or green . Sore throat improves, but coughing begins.
  • Days 5-7: Energy and congestion improve.
  • 1 week+: Cough usually tapers off after a week, but can take up to 3 weeks to fully resolve.

If your symptoms are much worse than these, such as coughing so hard you throw up, or coughing up bloody mucus, or if you have a fever over 102°F, you might have something more serious going on, like pertussis or pneumonia.

If a cold drags on, it can turn into a sinus infection that causes pain around the eyes, nose and/or sinus headaches. Chest colds cause chest congestion and a hacking cough that drag on for a few weeks.

The flu comes with similar symptoms but features a prominent fever, chills, headache, and body aches that usually last several days.

When Are You Contagious

Colds are most contagious two to four days after your symptoms first develop.

Most colds last for about a week, but it’s possible to spread the virus long after that, as it can live in your body for up to three weeks. That means you could spread your germs and make others sick even after you feel better.

Do Chills Or Exposure To Cold Temperatures Cause Colds

In a word – no. Some people may sneeze if their skin is cooled. More people catch colds when the weather temperature is cold than when it is warm outside because they tend to be inside more often and longer. People tend to blame cool temperatures for getting a cold rather than being in closer, prolonged contact with people who have a cold.

Some people associate exposure to the cool air from air conditioners as a cause of colds. Again, it is not the temperature that is the culprit.

Days 6 And : Symptoms Ease

The average duration of a cold is 7 to 10 days, and most people recover without any specific treatment. But cold symptoms may last longer or become more severe in people who have immune problems or other underlying health issues, such as diabetes, says Soma Mandal, MD, an internist with the Summit Medical Group in New Jersey. If you have a medical condition that puts you at increased risk for complications, reach out to your healthcare provider.

Be aware that it may take up to six weeks for a cough to disappear even after other symptoms fade, Dr. Mandal says. Usually, this is due to postnasal drip, which can continue to form while swollen and irritated nasal passages heal, she explains.

You can catch a cold any time of year, but its more likely during colder months. In winter, people stay indoors and are in closer contact with each other.

A recent study in mice suggests cold temperatures may also affect your immune systems response. Researchers found that when cooler air lowered nose temperature, mouse immune systems had a harder time stopping the rhinovirus from multiplying. The same may be true in humans.

How Long Are You Contagious

Youre generally contagious a few days before your symptoms start, and you may be contagious for as long as you have symptoms. Youre most likely to spread the virus in the first 2 to 3 days when the symptoms peak.

If youre sick, stay home from work or school. If your child is sick, keep them out of daycare or school. Avoid close contact with others, cover your mouth and nose when you cough or sneeze, and wash your hands after coughing, sneezing, or blowing your nose.

Days 1 And : Stuffiness Sore Throat And Runny Nose

Although you can have a cold start with a number of different symptoms, the most common first symptoms are congestion, runny nose, and sore throat, signs that the virus is directly affecting your respiratory system, says Nathan Favini, MD, an internist and the medical director of the nationwide healthcare system Forward.

In this first stage, its especially important to rest as much as possible to minimize fatigue and keep your immune system at full power.

Once people contract a virus that causes the common cold, they can begin transmitting it to others, even if they are not experiencing symptoms yet. This means a person can pass on cold viruses up to 23 days before they show signs of a cold.

After symptoms develop, people remain contagious for as long as they have them. This can mean they are able to spread the cold virus for up to around 2 weeks.

How Do You Treat Croup At Home

What is the incubation period for influenza a

When having any doubt regarding croup, it is best to convey to a medical practitioner at the earliest and make sure of the diagnosis. Once confirmed, the measures for curing the same should be administered. Croup in kids can easily be treated at home whereas in adults immediate medical attention is needed. Given below are some ways in which you can treat croup at home:

Staying Calm: Among the most important measures that can be taken to ease the condition of croup in kids is to stay calm and to try and keep the patient calm. If the kid cries, the breathing difficulty is further intensified making the situation worse. Distracting the child, cuddling him or even reading a book should be resorted to try and keep the child calm.

Use Humidifier: Keeping the air that the baby breathes laden with moisture is known to ease the breathing difficulty for the baby. Installing a humidifier in the babys room is sure to make the moisture in the air increase and relieve the symptoms of croup easily at home.

Hot Shower: Holding the baby in a closed bathroom with a hot shower running also works well towards making the air that the baby breathes moisture rich. Again this moisture works towards easing the infection of croup.

Taking a Walk: If its a cool and damp evening, then taking a walk outside with your baby would also work towards helping the baby inhale moist air. The dampness in the air also works well in treating the condition of croup.

What Are Home Remedies For A Cold

  • Fever and pain: Medications such as acetaminophen , ibuprofen , or naproxen or other anti-inflammatory medications often help decrease fever, reduce sore throat pain, and relieve body aches.
  • High fever usually is not associated with the common cold and may be indicative of “the flu” — a more severe illness caused by an influenza virus. Report to your doctor any temperature greater than 102 F/38.8 C.
  • Never give a child aspirin or medications containing aspirin. In children younger than 12 years, aspirin has been associated with Reye’s syndrome, a potentially fatal liver disorder.
  • Cough: The cough is a reflex that occurs when the airway passages are irritated. Cough preparations are usually divided into two main categories:
  • Suppressants: These act by blocking your cough reflex. As a general rule, use a suppressant for a dry, hacking cough. The agent usually found in over-the-counter cough suppressants is dextromethorphan .
  • Expectorants: A cough associated with excessive mucus production, or phlegm, warrants use of an expectorant. Guaifenesin is the most common active ingredient in over-the-counter expectorants . It is also used for nasal decongestion .
  • Sore throat
  • A warm saltwater gargle can relieve a scratchy throat.
  • Nasal spray decongestants act similarly to oral decongestants but have the advantage of acting only in the area applied, usually without the stimulant side effects. The most common active ingredient in nasal sprays is oxymetazoline .
  • How Can I Feel Better

    Like all viruses, those that cause colds have to run their course. Getting plenty of rest and drinking lots of fluids can do as much good as medicine as far as helping someone with a cold feel better.

    Whether you feel like sleeping around the clock or just taking things a bit easier, pay attention to what your body is telling you when you have a cold. A warm bath or heating pad can soothe aches and pains, and the steam from a hot shower can help you breathe more easily.

    Don’t worry about whether to feed a cold or starve a fever. Just eat when you’re hungry. And you might have heard that chicken soup can cure a cold. There’s no real proof of this, but sick people have been swearing by it for more than 800 years.

    According to the CDC, it takes most people 710 days to recover from a cold. Some symptoms may linger for a few days longer in some individuals. However, most people do not need medical treatment for this condition.

    Some can develop infections following a cold, such as sinusitis or an ear infection, which can extend the period of illness. However, doctors can diagnose and treat these secondary conditions with antibiotics.

    In rare cases, a person who is vulnerable to complications from colds can develop conditions such as bronchitis or pneumonia.ADVERTISEMENTCheck your vitamin levels with an at-home micronutrient test

    Any Time Your Child Is Sick

    The incubation period for common cold is

    If your child is sick, it’s best for them to stay home until they feel well again. If they have a fever, nausea, vomiting, diarrhea, or any kind of pain, aren’t hungry, or seem extra tired or clingy, they should stay home.

    How do you know when to keep your child home from school? The American Academy of Pediatrics recommends you answer a few key questions:

  • Does your child have a fever? Fevers of 101 F or more are generally a sign of illness, so children should stay home.
  • Is your child well enough to participate in class? If they seem too run-down to get much out of their lessons, keep them home.
  • Do they have an illness like the flu or pinkeye? If you think they might, don’t let them go back to school until you know they’re not contagious anymore. If possible, have them attend online classes.
  • Check with your child’s day care or school before you send them back to their regular schedules. Many places have rules about how long kids need to stay home. Usually it’s at least a full day after they don’t have any fever without medication.

    Hereâs what you need to keep an eye on:

    Fever is a sign that your body is fighting the germs that are making you sick. Itâs a common symptom of infections like flu. If itâs 101 F or higher, wait until your child is fever-free for at least 24 hours before sending them back to school.

    Pinkeye is contagious, and a child should stay home for the first 24 hours after treatment begins. Symptoms include eye redness, irritation, swelling, and pus.

    What Is The Incubation Period Of Common Cold

    The incubation period of the common cold is typically 36 to 48hours, but, in some cases, symptoms can arise within 12 hours, orslightly less, of catching the virus. From the time a cold virusenters the nose, it takes 8-12 hours for the viral reproductivecycle to be completed and for new cold virions to be shed in nasal secretions. This time period is called the”incubation period”.

    However, the incubation period differs depending on the specificcommon cold virus involved and the individual infected. There areover 200 viruses responsible for the common cold. According to theUS Centers for Disease Control and Prevention , the incubationperiods for a few of the most common causative viruses involvedwith the common cold are:

    Rhinovirus: 2-7 days.

    Adenoviruses: 2-14 days.

    Respiratory Syncytial Virus : 2-8 days

    Cold symptoms can also begin shortly after new virus particlesare first produced in the nose . The time from thebeginning of the infection to the peak of symptoms is typically36-72 hours. Adults can be infectious beginning a day or two beforefeeling any symptoms. Some people never develop symptoms even ifinfected allowing for more unknowing spread of the disease. Themost contagious period is typically on the third day followinginitiation of symptoms.
