Colds should be experienced by everyone, colds are actually a common disease, generally more frequent when the seasons change, and the contagion is very strong, we must strengthen physical exercise in daily life, improve immunity. So, when is the most contagious cold? Let's follow me to find out.

The incubation period after a cold is infected and after the onset of illness is contagious. Viruses, including influenza, are generally contagious for about 7 days, and can be transmitted from the end of the incubation period, of which the first 2 to 3 days of the disease are the most contagious. However, after normal body temperature, it is rarely poisonous, and the infectivity weakens, and the infectivity gradually disappears with the improvement of the condition.

Generally speaking, in the acute phase of a cold, when symptoms such as sneezing, nasal congestion, fever, runny nose, and sore throat are most obvious, if you have close respiratory contact with a person with low immunity, you may infect the other person, and the infection is the strongest. The cold is most contagious when it is most severe, because it is at that time when there are the most viruses. People with poor constitution and low resistance are the most susceptible to infection.

Therefore, during this period, it is more necessary to pay attention to wearing masks when going out, and avoid going to dense closed places. Colds can be transmitted from the end of the incubation period, and the contagion period is generally about 7 days, but in fact, it is not contagious until it is cured.

Controlling the source of infection is the most effective way to control the spread of colds, and if the people around you don't catch a cold, there will be no cold infection, and if you don't catch a cold, you won't infect others. Actively carry out ** and care, effective measures should be taken to destroy and isolate the secretions of colds (such as nasal discharge, phlegm and other substances containing cold viruses), and nasal discharge and phlegm should be wrapped in toilet paper and thrown into the non-** trash can to avoid infecting the contact population.

The history of the virus is about 5 to 7 days. In the first three days of fever and cold, the symptoms may be more serious, there will be runny nose, tears, cough, sore throat, and even chest tightness, shortness of breath and other symptoms.

If the illness is severe, it is necessary to go to the outpatient clinic of the hospital for a blood test to determine whether it is a viral infection or a bacterial infection. If the white blood cell count is high, it may be combined with the infection of the bacteria, and the antibiotic of cephalosporin can be taken internally.

If the baby has a viral cold and a blocked nose, the mother can consider salt water nasal drops, such as up and down the nose ten minutes before drinking, which is conducive to improving the thick runny nose, making the baby more and more comfortable, and reducing the damage of viral colds and runny nose.

Factors such as climate change and body colds can easily cause colds in the elderly. Once you have a cold, you should pay attention to taking different measures at different stages. 1 The 3-day period when people are infected with the influenza virus does not become ill immediately after being infected is called the incubation period of the flu.

The incubation period of influenza is 1 to 3 days, with an average of 2 days.

Generally** include taking a break, drinking plenty of water, eating a diet that is easy to digest, and paying attention to ventilation. Medications** may be used to relieve symptoms. Antipyretic analgesics include compound aspirin, indomethacin, acetaminophen, ibuprofen and other drugs, which are suitable for patients with fever, muscle aches, and headaches.
