Early spring is a high-incidence season for lower respiratory infections, particularly among children, with rates exceeding four times those in summer. Pneumonia often follows an upper respiratory infection, typically beginning with sudden, brief chills followed by fever, cough, and breathing difficulties, accompanied by nausea, vomiting, and muscle pain. Coughing initially produces no phlegm but gradually develops into sputum containing pus or blood streaks.
Preventive Measures: Avoid indiscriminate use of vinegar fumigation or Banlangen (Isatis root) to prevent disease transmission. Ensure adequate ventilation in work and living spaces; adjust clothing appropriately and increase outdoor exercise. Seek prompt medical attention if fever or cough symptoms develop.
2. Hepatitis>Hepatitis A and E are intestinal infectious diseases caused by the hepatitis A and E viruses, respectively. Clinically, they primarily manifest as fever, nausea, vomiting, liver pain, jaundice, and abnormal liver function.
Prevention: Avoid consuming raw or undercooked seafood, especially shellfish like hairy clams. Develop the habit of washing hands before meals and after using the restroom.
3. Mumps
Mumps infections are common during the transition from winter to spring. This infectious disease is caused by the mumps virus and spreads through contact or respiratory droplets. Primary symptoms include swelling below the earlobe centered around the ear, accompanied by significant pain or tenderness, difficulty opening the mouth, fever, and decreased appetite.The incubation period is typically 2-3 weeks. Swelling often begins on one side before appearing on the other, accompanied by pain and warmth.
Prevention: Administer the mumps live attenuated vaccine via injection; use intranasal spray or aerosol inhalation in a mist chamber.
4. Myocardial Infarction
Prior to onset, patients often experience prolonged angina lasting over 3–5 minutes, or even up to half an hour. Concurrent symptoms may include chest tightness, palpitations, shortness of breath, fatigue, and drowsiness. During spring and winter, fluctuating temperatures between cold and warm conditions can trigger cold exposure, potentially inducing myocardial infarction.
Prevention: Maintain warmth and avoid exposure to cold; balance work and rest to prevent excessive fatigue and long-distance travel; keep a positive mindset; avoid strenuous activity immediately after overeating; limit high-fat foods, and obese individuals should control their diet.
5. Measles Measles is most prevalent in winter and spring, spreading through respiratory droplets.Individuals who have never had measles or received the measles vaccine are generally susceptible, with the highest incidence among children aged 6 months to 5 years. Measles is an acute respiratory infectious disease caused by the measles virus. Its clinical features include fever, cough, runny nose, conjunctival hyperemia, oral mucosal rash, and generalized maculopapular rash. It often leads to pneumonia, posing a life-threatening risk to infants and young children.
Prevention: Keep children away from crowded places. If symptoms appear, isolate and treat the child promptly. Isolate measles patients until 5 days after the rash appears.
