Both colds and flu are contagious and are caused by viruses. However, viruses that cause colds are not the same as those that cause flu. Although the typical incubation period for influenza is about one to four days, some adults can be contagious from about one day before onset of symptoms for up to two weeks. Other people who develop complications, such as pneumonia, may extend contagious period for week or two. For colds, most individuals become contagious about day before cold symptoms develop and remain contagious for about five to seven days. Some children may pass flu viruses for longer than seven days. Colds are considered upper respiratory infections. Flu may also cause lower respiratory infections. For both cold and flu, early symptoms may be similar. Symptoms and signs include cough, runny nose, and feeling tire. If you know you have had contact with someone with a cold or flu in the past few days, you should suspect you may have become infected. However, flu symptoms are generally more intense than cold symptoms. People with flu can develop fever, body aches, chills, and headaches, and some develop nausea and vomiting. Cold symptoms are much milder and usually do not require MEDICAL care. However, if you suspect you have the flu, you should seek MEDICAL care. Flu is often diagnosed with rapid tests available to most physicians. Common colds and flu are easily spread from person to person, Flu is most often by droplets produced by coughing and sneezing. Cold viruses in droplets are spread mainly hand to hand. These droplets contain infectious viruses. Occasionally, these droplets land on various surfaces and, depending on the survivability of virus type, can be transferred when an uninfected individual touches contaminated surface and subsequently touches his / her mouth or nose. In most instances, individuals with a cold will resolve their symptoms without MEDICAL intervention in about one week, although sometimes cough may last longer. However, at this point in time, cough is not spreading contagious virus. When cold symptoms and signs resolve, person is cure of cold. Flu is similar except that symptoms are more severe and, in some individuals, MEDICAL intervention may be require. However, depending upon influenza strain and severity of infection, some individuals may require hospitalization. A cure for these individuals occurs when symptoms resolve and the patient is discharged from hospital. Stomach flu is not caused by cold or by flu viruses. The term stomach flu is a nonspecific term that describes symptoms of nausea, vomiting, and diarrhea. Although these symptoms may occur with the flu, flu is a respiratory infection. In most individuals with only stomach flu, causes are usually non - flu type viruses. Similarly, cold sores are not actually caused by cold viruses but by herpesviruses.

Mastoiditis

Mastoiditis in children and adults is inflammation and / or infection of mastoid bone, which is located behind the ear. The most common cause of mastoiditis is inner ear infection or otitis media. Acute mastoiditis lasts for a short period, while chronic mastoiditis can last for months to years. Symptoms of acute mastoiditis in children and adults include, pain and swelling behind ear, pus draining from the ear, and low - grade Fever. Complications of mastoiditis include meningitis, abscess, dizziness, and conductive hearing loss. Mastoiditis requires antibiotic treatment so it cannot be treated at home with natural products or home remedies; However, home remedies may help reduce symptoms of pain, inflammation, and fever. Some individuals will need surgery to cure their infection.


Are ear infections contagious?

A doctor looks in ear canal with a medical instrument called otoscope, which makes it possible to look in the ear canal down to the eardrum for signs of inflammation and infection. With otoscope pointing in ear, the doctor looks to see if the eardrum is bulging, indicating that fluid has gathered in the inner ear. If that fluid is red in color or cloudy, that points to infection in the middle ear. The doctor also looks at the ear canal for skin irritation, inflammation, and redness. These are indications of different kinds of ear infection often referred to as swimmers Ear. The doctor also look for fluid leaking from the eardrum, which may or may not be infect, but indicate that the eardrum has been damage. Only after examining the ear can a doctor identify the type of ear infection present and what treatment is needed.


Swimmers ear

Swimmers ear, also called otitis externa or outer ear infection, is triggered by moisture in the ear canal that creates a welcoming environment for bacteria or fungus to grow. It can also be caused by damage to skin in the ear canal. Putting foreign objects in ear, irritation from hair products, and dry skin conditions like eczema, psoriasis, or acne can cause scratches, flaking, and inflame skin in the ear canal. Once skin in the ear canal is affected, inflammation and swelling occurs, causing pain, itchiness, and possibly pus to discharge. Treatment prescribed depends on whether a bacterial infection or fungus is present. Generally, outer ear infection clears up in 7 - 10 days, but it can last longer.


Middle Ear Infection

Middle ear infection, or otitis media, often starts with viral nose or throat infection, like cold or flu. Infection spreads to the middle ear through Eustachian tubes, which can block keep mucus from draining away and creating conditions for bacteria to grow. Pain is felt when buildup of mucus in the middle ear stretches eardrum. A doctor, using otoscope, looks at the eardrum for signs of bulging or tear. Infection is evident when mucus builds up behind the eardrum is red in color or cloudy. Mucus draining into the ear canal indicate tear to eardrum. Middle ear infections can clear up completely in 1 - 2 weeks and the earache that comes with it can go away in 2 - 3 days. For this reason, if there is no clear indication of infection, doctor might wait 48 hours before prescribing antibiotics.

Your sneezing, sniffling nose, and watery eyes might not be contagious at all. If they happen at certain times of year and they stick around for a few weeks or months, you could have allergies. Allergies can be triggered by irritants in your environment, such as: pollen, pet dander dust mites mold. One way to tell the difference between allergies and contagious infection is that allergies typically do cause symptoms such as fever and body aches. Avoiding your triggers is the best way to ward off allergy symptoms. To relieve allergy symptoms when they happen, try taking one or more of these medications: antihistamines block the effects of histamine. Your immune system releases this chemical when you have an allergic reaction. Some antihistamines can make you tire. They can also cause other side effects such as constipation and dry mouth. Decongestants narrow blood vessels in your nose to bring down swelling and reduce running. These drugs can make you jittery, keep you awake at night, and increase your blood pressure or heart rate. Nasal steroids control inflammation and related swelling in your nose. Some steroid solutions can dry out your nose or cause nosebleeds.

People with flu are most contagious in the first three to four days after their illness begin. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children and some people with weakened immune systems may pass the virus for longer than 7 days. Symptoms can begin about 2 days after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms. During this time, those people may still spread the virus to others.

Treating cold and flu

Flu, which is caused by influenza viruses, also spreads and causes illness around the same time as common cold. Because these two illnesses have similar symptoms, it can be difficult to tell the difference between them based on symptoms alone. In general, flu symptoms are worse than common colds and can include fever or feeling feverish / chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches and fatigue. Flu can also have very serious complications. Cdc recommends yearly flu vaccination as the first and best way to prevent flu. If you get the flu, antiviral drugs may be a treatment option.
