Cold in adults
Cold is a colloquial name for a whole group of acute inflammatory diseases of the upper respiratory tract. Supercooling is only one of the reasons that provokes them. But in most cases, we associate such a disease with hypothermia. This is because most often it occurs in the cold season, when the body is weak and exhausted, and people spend most of their time indoors exchanging viruses and bacteria. But the medical card of a patient with a cold usually gives the official name of the disease – ORVI (acute respiratory viral infection), or ORZ (acute respiratory disease).
Another popular expression is the cold on the lip. This is an exacerbation of herpes viral infection, which may also occur in part against the background of hypothermia and reduced body defenses.
How can one catch a cold?
The main way of infection transmission is airborne. When coughing, sneezing and even during breathing, a sick person releases into the air a lot of viruses or bacterial cells. When breathing in contaminated air, a healthy person faces an infection that seeks to gain a foothold in the mucosa of the respiratory tract. If the concentration of pathogens in the air is low (the room is well ventilated, the distance between the patient and the healthy person is several meters) and the person has a strong immunity, he may not get sick. But if the disease is too close, the air is dry, in addition, the body is weakened by stress, fatigue, chronic diseases, the probability of transmission is almost 100%.
Sometimes you can get EDS through household items (towel, cup, spoon), if you use them immediately after the disease.
You can get herpes, which causes a cold on the lips, through contact with a sick person: a handshake, kisses, common items and dishes.
Signs and symptoms of colds
ODS is characterized by a slow onset of the disease: first there is a weakness, a slight swelling in the throat or other symptoms that gradually increase. This is one of the signs by which “normal” cold can be distinguished from influenza. The latter is characterized by a sudden and rapid onset of the disease.
The signs of a cold appear a few hours or days after infection – the incubation period can be up to 2 days. At this time, a person does not yet realize that he is sick, but can infect others.
The main symptoms of a cold:
- swelling and sore throat;
- silence of the voice;
- coughing, sneezing;
- congestion, runny nose, tears;
- fever, chills;
- increase in lymph nodes;
- pain and scrapes in muscles and joints;
- no appetite;
- insomnia or, conversely, sleepiness.
- In some cases, there may be signs of mild digestive disorder.
A person should not necessarily have all the symptoms of a cold at once: cough or runny nose may appear on day 2-3. Also, adults may have a cold without fever or with a slight increase in temperature within 37.3-37.5 °. A child’s cold almost always occurs with a high fever and pronounced symptoms, often with signs of intestinal disorder.
