Symptom: Any subjective evidence of disease. In contrast, a sign is objective. Blood from a nostril is a sign; it is apparent to the patient, physician, and others. Anxiety, low back pain, and fatigue are all symptoms; only the patient can perceive them.
What is a fever?
A fever is a temporary increase in your body temperature, often due to an illness. Having a fever is a sign that something out of the ordinary is going on in your body.
For an adult, a fever may be uncomfortable, but usually isn’t a cause for concern unless it reaches 103 F (39.4 C) or higher. For infants and toddlers, a slightly elevated temperature may indicate a serious infection.
Fevers generally go away within a few days. A number of over-the-counter medications lower a fever, but sometimes it’s better left untreated. Fever seems to play a key role in helping your body fight off a number of infections.
In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature. Although the most common causes of fever are common infections such as colds and gastroenteritis, other causes include: Infections of the ear, lung, skin, throat, bladder, or kidney.
Depending on what’s causing your fever, additional fever signs and symptoms may include:
– Chills and shivering.
– Muscle aches.
– Loss of appetite.
– General weakness.
No matter the illness, keep your child home if she has a fever. It may seem harmless enough, but assume any fever is a symptom of a contagious condition. Viruses that cause fevers are contagious as long as the fever is above a 100.4 degrees F.
The type of infection causing the fever usually determines how often the fever recurs and how long the fever lasts. Fevers due to viruses can last for as little as two to three days and sometime as long as two weeks. A fever caused by a bacterial infection may continue until the child is treated with an antibiotic.
The Centers for Disease Control and Prevention also recommends staying home for 24 hours after a fever and other flu-like symptoms (chills, sweating, flushed skin) have cleared up.
1. If the temperature is 103 F (39.4 C) or greater (fever is too high)
2. If the fever lasts more than seven days.
3. If the fever symptoms get worse (concern if fever is increasing toward 39.4 C)
What is a runny nose?
A runny nose is excess drainage produced by nasal and adjacent tissues and blood vessels in the nose. This drainage may range from a clear fluid to thick mucus. Runny nose drainage may run out of your nose, down the back of your throat or both.
The terms “rhinorrhea” and “rhinitis” are often used to refer to a runny nose. Strictly speaking though, rhinorrhea refers to a thin, relatively clear nasal discharge. Rhinitis refers to inflammation of the nasal tissues from a number of causes, which usually results in a runny nose.
Nasal congestion may or may not accompany runny nose.
Runny nose (clear and watery)
You usually don’t get a fever with a cold. If you do, it may be a sign you’ve got the flu or an infection with a bacteria.
Cold symptoms usually start 2 or 3 days after a person has been exposed to the virus. People with colds are most contagious for the first 3 or 4 days after the symptoms begin and can be contagious for up to 3 weeks. Although some colds can linger for as long as 2 weeks, most clear up within a week.
This can happen by direct physical contact with someone who has a cold, or by touching a surface contaminated with their germs and then touching your nose or mouth. You can also catch it from infected droplets in the air released by a sneeze or a cough.
