Four seas network: in summer, the indoor and outdoor temperature difference is too large, and it's easy to get a cold if you go in and out frequently.

The difference between stream and cold
Influenza is not only an acute respiratory infection caused by influenza virus, but also a highly infectious and fast spreading disease. It is mainly transmitted by the droplets in the air, the contact between people or the contact with the contaminated objects. The typical clinical symptoms are: acute high fever, general pain, significant fatigue and mild respiratory symptoms. Generally, autumn and winter is the high incidence period, which causes serious complications and death.
Flu and cold
Influenza is not a common cold, but two completely different diseases.
Influenza influenza is a systemic disease involving upper respiratory tract caused by influenza virus infection;
Common cold is mainly caused by respiratory syncytial virus, rhinovirus, adenovirus, coronavirus and parainfluenza virus. In addition to the common cold, acute upper respiratory tract infection also includes acute pharyngitis, acute tonsillitis, acute laryngitis and acute tracheitis.
Influenza usually has more symptoms and complications than common cold, and it can be accompanied by severe conditions such as pneumonia, with a higher mortality rate. The Centers for Disease Control and Prevention (CDC) estimates that in the United States, 200000 people are hospitalized for influenza every year, and 36000 people die. However, when patients come to the hospital for treatment, even if the symptoms are very similar to influenza, it is very difficult for doctors to diagnose influenza, and only influenza like cases can be diagnosed. By definition, influenza like cases can be diagnosed as long as the body temperature (axillary temperature) is greater than 38 & deg; C, accompanied by at least one respiratory symptom (such as sore throat, cough, etc.). However, the diagnosis of 'influenza' requires' etiological diagnosis', including the cultivation of influenza virus or detection of influenza virus antigen from respiratory specimens. At present, most general hospitals do not have the ability of etiological detection.
How to tell if the baby has influenza or a cold?
Flu and cold have similar symptoms, so it's easy to confuse them. But they are very different respiratory diseases. Colds can happen all year round. Many viruses can cause colds. But influenza is different from common cold. It is caused by influenza virus. Influenza has a certain seasonality, mainly concentrated in winter and spring, generally from December to February next year. During this period, there will be more babies infected with influenza.
What symptom does darling get flu to have?
The typical symptoms of influenza are high fever, headache, cough, general pain, fatigue, sore throat, etc. these symptoms are also common cold, but common cold rarely presents general symptoms, such as pain around the body. Influenza fever is higher than common cold, which is mainly high fever. The so-called high fever refers to 38.5-39 & deg; C or even 40 & deg; C. influenza fever is generally higher in babies. Generally speaking, the smaller the baby is, the higher the fever is. High fever can lead to dehydration, convulsion, etc. Sometimes the baby flu will have gastrointestinal symptoms, such as nausea, vomiting, diarrhea, etc. at the same time, influenza is easy to induce a variety of serious complications, such as pneumonia, myocarditis, otitis media, meningitis, etc.
How can babies prevent influenza?
For babies, the risk of influenza is high. Baby is a high incidence population of influenza. During the general influenza epidemic, the infection rate of baby can reach 30% - 40%, or even higher. In general, 6-35 months is the stage when the baby's autoimmune function is developing and maturing. Compared with older children, babies in this age group have weaker resistance to external viruses, and are more likely to be infected with influenza in the event of influenza epidemic. Therefore, from the perspective of protecting the health of the baby, parents should consider vaccinating the baby against influenza. Since there is no specific medicine for influenza at present, vaccination is the most effective way to prevent influenza. Vaccines are not for everyone. If the baby is in the active period of acute infection, fever and chronic disease, the vaccination should be postponed, while those who are allergic to eggs are forbidden to use influenza vaccine.
