Colds, allergic rhinitis, and flu share many of the same symptoms, such as a runny nose, cough, and sore throat. So what are the symptoms of a cold and what are the signs to distinguish it from the flu or allergic rhinitis?

The signs and symptoms of a cold can vary from person to person. In general, a cold usually starts with a sore throat, and before that, you may also experience the following symptoms:
Stuffy nose Can't smell scents Sneezing Runny nose Watery eyes Headache Sore throat Cough; Swollen lymph nodes. Systemic symptoms
Fatigue Chills Body aches Fever Fever Chest discomfort Difficulty breathing deeply

2.1. Colds Answering the question "What's the fever?", doctors said that people with colds are often not accompanied by fever symptoms. If so, this is most likely a sign of the flu or a bacterial infection. During the first few days of illness, a cold and runny nose will have a clear and liquid discharge, but then gradually become thicker and cloudy (yellow). or green). You may also have a cold, sore throat, a mild cough that usually lasts into the 2nd week of a cold. Cold symptoms usually begin 1-3 days after infection, rarely come on suddenly and will Lasts for about 3-7 days. After this time, even though the symptoms are no longer as intense as before, you will still feel tired and irritable for at least another week. The most contagious period is during the first 3 days of illness, but the risk of transmission will continue through the first week.

2.2. Allergies Sometimes you can mistake a cold with a runny nose for an allergy. If symptoms start quickly and end in 1
- 2 weeks, it's most likely not an allergy. Allergies happen when your immune system is overworked to protect you against germs. Your body overreacts to things like dust or pollen. Then chemicals like histamine are also released. This causes your nasal cavities to swell, leading to a runny nose, coughing, and sneezing.
Allergies are not contagious, but some people can run them in families.
2.3. Colds and flu Taking your temperature is the way to tell the difference between a cold and the flu. A mild case of the flu usually has cold-like symptoms, but a cold is rarely a malaria cold or a fever higher than 38°C (about 101°F). In addition to fever, the flu also causes body aches and headaches, and is more tired than a cold.

Colds are not usually dangerous to everyone, except in infants. Symptoms will resolve on their own without special treatment. But when you get sick, a cold can lower your body's resistance, making you more susceptible to bacterial infections.
See a doctor if your cold symptoms are severe and show no signs of abating. Throat and ear exams, as well as listening to the lungs, can be done in the clinic. Your doctor may also take throat swabs with a long cotton swab to test you for an infection that requires antibiotic treatment.
