Bacterial infections can cause low-grade fever and cough. The key management approaches include seeking timely medical care for accurate diagnosis, using antibiotics as prescribed, targeted symptom relief, ensuring adequate rest, and adjusting dietary habits. Immediate medical attention is required if symptoms such as persistent high fever, worsening cough with difficulty breathing, or significantly deteriorated mental status occur.
1. Seek timely medical care for accurate diagnosis: Bacterial infections must be confirmed through tests such as complete blood count and sputum culture to avoid misdiagnosis as viral infection, which could delay treatment. Accurate identification of the type and severity of infection provides a basis for appropriate therapy.
2. Use antibiotics properly as directed by a physician: Do not purchase or take antibiotics without medical guidance. Follow the doctor’s instructions precisely regarding dosage and duration of treatment. Avoid stopping medication prematurely, which may lead to recurrent infection or development of antibiotic resistance.
3. Targeted symptom relief: For low-grade fever, use physical cooling methods such as wiping with lukewarm water to regulate body temperature. For significant cough, use cough suppressants or expectorants under medical guidance to prevent severe coughing from disrupting rest.
4. Ensure adequate rest: The body needs energy to fight infection. Reduce physical activity and ensure sufficient daily sleep. Avoid overexertion, which may weaken immunity and worsen the condition.
5. Adjust diet: Choose light, easily digestible, and nutrient-rich foods. Increase intake of fruits and vegetables rich in vitamins, and drink plenty of water to keep the respiratory tract moist. Avoid spicy, irritating, or greasy foods.
Daily care should include maintaining indoor air circulation by regularly opening windows for ventilation to reduce bacterial growth. Practice good personal hygiene, wash hands frequently to prevent cross-infection, dress appropriately according to temperature changes, avoid getting chilled (which may worsen symptoms), and maintain a positive mindset to support recovery.
