Write 10 line about colddisease

Answer 1

The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the nose.[7] The throat, sinuses, and larynx may also be affected.[5] Signs and symptoms may appear less than two days after exposure to the virus.[5]These may include coughing, sore throat, runny nose, sneezing, headache, and fever.[2][3] People usually recover in seven to ten days,[2] but some symptoms may last up to three weeks.[6]Occasionally those with other health problems may develop pneumonia.[2]

Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common.They spread through the air during close contact with infected people or indirectly through contact with objects in the environment, followed by transfer to the mouth or nose.Risk factors include going to daycare, not sleeping well, and psychological stress.The symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves. In contrast, those affected by influenza can show similar symptoms as people with a cold, but symptoms are usually more severe.Additionally, influenza is less likely to result in a runny nose.

There is no vaccine for the common cold.[The primary methods of prevention are hand washing; not touching the eyes, nose or mouth with unwashed hands; and staying away from sick people.Some evidence supports the use of face masks.There is also no cure, but the symptoms can be treated. Zinc may reduce the duration and severity of symptoms if started shortly after the onset of symptoms.Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may help with pain.Antibiotics, however, should not be usedand there is no good evidence for cough medicines.

The common cold is the most frequent infectious disease in humans.The average adult gets two to three colds a year, while the average child may get six to eight. Infections occur more commonly during the winter. These infections have existed throughout human history.

Answer 2

A cold – also called infectious rhinitis – is a very common viral infection of the nose and throat. Doctors call it a "self-limiting" condition, which means that it only lasts so long and goes away on its own.

In most people, colds are relatively harmless, but they have important social and economic impact. It is estimated that 40% of time lost from work and 30% of school absences are due to the common cold. Cold symptoms normally improve within 1 week, although some may last longer, especially in children.

There are over 200 different viruses responsible for causing colds. The most common type are the rhinoviruses, which cause about 40% of colds in adults. Colds occur most often from fall to early spring, when people tend to stay indoors – facilitating easy spread of these viruses.
