Presentation of safety education knowledge (excerpt)
First, the prevention of common diseases in spring
The weather is dry in spring, and climate change is the pathogenesis and preventive measures of repeated upper respiratory tract infections, chickenpox, mumps and other epidemic or infectious diseases.
1, Influenza: Clinical manifestations: chills, high fever, headache, retrobulbar pain, dry throat pain, stuffy nose, dry cough and general aches. Physical examination: flushing. Pharyngeal congestion, punctate erythema, tonsil enlargement, dry rales can be heard in the lungs. After 1-2 days, the above symptoms reach the peak, and the temperature drops within 3-5 days, but fatigue and cough can last for 1-2 weeks. Treatment: immediately isolate, stay in bed, keep enough water, and treat with antiviral symptoms.
2. Chickenpox: Chickenpox is caused by chickenpox and is a mild respiratory tract and acute infectious disease. Its clinical manifestations include fever, sore throat and fatigue. After about a few hours or 1-2 days, a rash appeared on the trunk, followed by a rash. At first, the skin will itch until herpes. It is very important to take care of this disease. Pay attention to the skin and reduce scratching and infection.
3. Mumps: Acute respiratory infectious disease caused by parotid virus, which is mainly transmitted through children's saliva and droplets. Its clinical symptoms include fever and sore throat for several hours, and then parotid gland swelling appears two days later, first on one side, then on the other side, with the earlobe as the center, developing forward and backward, with unclear edge, burning and tenderness in local skin, and obvious edema in tissues around parotid gland. The parotid gland can be treated, rested and isolated.
4, acute conjunctivitis: also known as pink eye, manifested as conjunctival congestion and edema, thick secretions, strong infectivity, causing mutual infection between groups and families. Cold compress should be used to relieve symptoms and treat eye water for acute attack.
The above diseases are highly contagious, so they should be isolated in time, carefully cared and treated symptomatically. When the climate is warm, do more outdoor activities. Fresh air and sunshine can promote metabolism, enhance physical fitness and disease resistance, and reduce respiratory infections.
Second, electricity and fire safety
Spring is a period of high fire incidence. In order to avoid the adverse consequences caused by the use of fire and electricity, please pay attention to the following points:
1, don't throw cigarette butts and matches;
2. Don't smoke in bed;
3. Don't light candles;
4. Don't set off fireworks and firecrackers near flammable materials;
5. Do not use high-power electrical appliances;
6. Don't pull the wires indiscriminately.
Third, psychological safety.
In spring, young students are prone to anxiety. If you don't have a good rest and encounter bad things again, you will be easily agitated, which will lead to psychological problems. Have a good rest, eat well, exercise well and be in a good mood. Students should care about and help each other; Teachers often talk to their classmates and do a good job in counseling.
