A cold is a common illness with common symptoms such as sneezing and a runny nose. But to properly understand colds and prevent colds, not everyone knows. This article will share with you helpful information about colds and effective prevention.
What is a cold?
A cold is a condition in which the body shows symptoms related to the upper respiratory system, such as sneezing, runny nose, etc. Viruses cause colds, and the spread of the disease is very high. Because there are up to 200 types of viruses, the body’s resistance cannot fight all these viruses. The condition can recur continuously, especially in young children and people with weak opposition.
Important. Although it is not considered too dangerous, if the disease is left untreated or untreated for a long time, the cold will make the patient tired, uncomfortable, and weak and cause serious problems. Specifically, acute nasopharyngitis will turn to acute bronchitis, or more dangerously, pneumonia. Therefore, it is advisable to take the initiative to prevent colds from the very beginning.
Causes, symptoms, and complications of a cold
Causes of colds
As noted above, colds are caused by viruses. Of the 200 cold virus strains, 50% come from rhinovirus strains; the rest are caused by other viruses such as respiratory syncytial virus, parainfluenza virus, adenovirus, coronavirus, and metapneumovirus. In particular, the rhinovirus strain is especially dangerous when it causes colds and triggers asthma attacks and has a connection with sinus and ear infections.
Caused by a virus, colds can repeatedly recur in a person. On average, an adult can be infected 3-6 times a year, while this number can be 10-12 times in children. However, this is just an average statistic, and in fact, there are still people who do not get infected once a year, but there are also people who have more times. And this is not unusual. In general, the number of colds depends on the age, resistance, and how to prevent colds of each person.
Colds can be transmitted from person to person through direct or indirect contact with the saliva or secretions of an infected person. Even if an infected person coughs or sneezes and the person standing next to him is not wearing a mask, they can still be infected. Therefore, both sick people and contacts should take precautions to spread the disease actively.
Symptoms of a cold
It is not difficult to recognize the signs of a cold. Usually, when infected with the virus, the patient will show the following symptoms:
- Stuffy nose.
- Sore throat.
- Mucus (sputum) runs down the neck.
- Fatigue, muscle pain, headache, loss of appetite.
- Body temperature rises. Children may experience fever and rash.
These symptoms appear 2 – 5 days after exposure to the virus and subside after 1 – 2 weeks.
Complications of a cold
Colds cause many complications such as acute bronchitis, acute pneumonia, sinusitis, otitis media, etc. For people with asthma, emphysema, chronic bronchitis, when infected with colds, the illness becomes more severe with acute exacerbations. Therefore, it is necessary to have convenient cold treatment methods to avoid causing dangerous complications.
