Recently, as the temperature picked up, Liu Bin, a 3-year-old boy who lives in Fuzhou City, developed acute high fever, headache, muscle aches, general weakness and other symptoms, and often otitis media, and was only found to be suffering from influenza when he was sent to the hospital for treatment. “Spring is the high season for diseases such as influenza, rubella, mumps and epidemic hemorrhagic fever.” Generally speaking, the most common infectious disease entering March is influenza, and there are two types by typology, A and B. Most patients suffer from influenza A, and relatively few from B. Influenza virus can be spread by droplets in the air, but also by receiving infected people or objects contaminated with the virus and “hit”, with acute high fever, generalized pain, significant weakness and respiratory tract and other typical symptoms. There is a big difference between influenza and the common cold, and it is dangerous to “misidentify” the disease. The common cold is generally a bacterial virus infection of the upper respiratory tract, and the toxicity is not that strong, the onset of the process is slow, drink more water and eat more vegetables and fruits, can better reduce the symptoms of the cold. The flu virus, on the other hand, has a rapid onset, is highly contagious and virulent, with fever at the beginning, which can be as high as 39℃-40℃, headache, sore throat, aching limbs, etc. Taking medicine can only temporarily suppress the virus. If you rely only on drinking more water, you may aggravate the disease and transform it into other complications such as myocarditis and pneumonia. The risk of outbreaks of influenza, rubella, mumps and epidemic hemorrhagic fever is small and the possibility of an epidemic is unlikely. “In addition to influenza, in previous years there were individual cases of chickenpox in schools in the spring.” Dr. Ren Rongna, chief physician, said that chickenpox is mainly a contact-based infection. In addition, every year to the spring and summer, hand, foot and mouth disease will also have a higher risk of transmission, resulting in some immunity is low, the age of young children become the main target of infection. ”Prevention of influenza, chickenpox, and the above-mentioned flu, rubella and mumps is, of course, best done with vaccination.” Ren Rongna said that in addition to vaccination, children usually go to less densely populated, poorly ventilated public places to get together. Parents should urge their children to develop good hygiene habits such as washing hands and changing clothes, pay attention to ventilation in the room, ensure dietary hygiene, regular rest and rest, get enough sleep every day, strengthen physical exercise and combine work and rest, etc. If your child has a fever and vomiting and diarrhea, consult a doctor as soon as possible to find out the cause. If your child has a high fever of 39 degrees Celsius or higher, you must go to the hospital immediately. If it is identified as an infectious disease such as influenza or norovirus, it is important to do a good job of self-isolation, such as wearing a mask when suffering from influenza, to prevent the virus from being transmitted to others through droplets due to coughing, sneezing or close conversation. During the period of isolation and observation, daily necessities and food items should be strictly separated from those around you until the symptoms disappear and they are no longer contagious. In addition, when kissing children, it is easy to have saliva contact, and it is natural to “exchange” bacteria that are often present in the mouth of both parties. If there are no ulcers in the mouth, and the body is healthy and has sufficient resistance, the bacteria will not easily do evil, and the bacteria in the mouth can “coexist peacefully”. However, if the kiss is too intense, bite the lips or flesh of the teeth, children’s resistance is weak, there is a risk of “kissing disease”, causing mouth sores, throat inflammation, and even into the blood after causing fatal scurvy. Therefore, try not to kiss children to avoid contracting “acute kissing disease”
