Bird flu symptoms in children

Avian influenza is a relatively common type of influenza. It is a virus that is mainly transmitted by poultry or some wild birds. The incidence of avian influenza was relatively high in previous years. If a child gets avian influenza, the harm is relatively large. After all, children's immunity is relatively poor. It often leads to lung heat type influenza, which can cause persistent high fever, severe coughing, and even coughing up blood and other symptoms.

Bird flu symptoms in children

1. Pneumonia-type influenza:

It is common in the elderly, children, and people with low immunity such as those with existing heart and lung diseases. The main manifestations are persistent high fever, severe cough, coughing up blood or purulent sputum, rapid breathing, hypoxia and cyanosis, and moist rales in the lungs. Chest X-ray examination showed scattered irregular flocculent shadows in both lungs. Sputum culture showed no growth of pathogenic bacteria, but influenza virus could be isolated.

2. Simple influenza:

Most of the cases have a sudden onset, with chills and high fever, and the body temperature can reach 39℃ to 40℃, often accompanied by systemic symptoms such as headache, extreme fatigue, muscle and joint pain, loss of appetite, and often accompanied by sore throat, dry cough, nasal congestion, runny nose, and discomfort behind the sternum. The body temperature usually drops to normal levels 3 to 4 days after the onset of the disease, and systemic symptoms gradually improve, but it usually takes 1 to 2 weeks for the cough symptoms to disappear and physical strength to recover. Mild influenza is very similar to the common cold, with mild symptoms and recovery within 2 to 3 days.

3. Influenza in special populations:

Generally speaking, healthy children infected with influenza viruses may only show mild symptoms of influenza, with the main symptoms being fever, cough, runny nose, stuffy nose, sore throat and headache. A small number of children experience myalgia, vomiting and diarrhea. The clinical symptoms of influenza in infants and young children are often not very typical. Due to the incomplete development of the nervous system, high fever convulsions may often occur. Neonatal influenza is relatively rare, but it is often complicated by pneumonia and often has symptoms of sepsis, such as lethargy and refusal to feed. In children, laryngitis, tracheitis, bronchitis, pneumonia and gastrointestinal symptoms caused by influenza viruses are more common than in adults.
