Abstract
Influenza A(H1N1) belongs to the school of warm diseases and can be categorized into violence qi, caused by external attack of the six pathogenic evils. The lungs governing defensive qi have correspondence to skin and hair. The external pathogenic evils firstly attack the lungs to cause the stagnant defensive qi. The resulted defensive-exterior symptoms are actually excessive exterior heat syndrome. For cases with vital qi insufficiency, the pathogenic evils fight against defensive qi to cause visceral dysfunctions. The pathogenic evils then transform into heat for further attacks, which may impair nutrient qi to cause the syndrome of dual blaze of qi nutrient aspects. In the advanced stage, the subsided pathogenic evils and the deficient vital qi impair both qi and yin.

15.1 Etiology and Pathogenesis of Influenza A (H1N1) by TCM

Influenza A (H1N1) belongs to the school of warm diseases and can be categorized into violence qi, caused by external attack of the six pathogenic evils. The lungs governing defensive qi have correspondence to skin and hair. The external pathogenic evils firstly attack the lungs to cause the stagnant defensive qi. The resulted defensive-exterior symptoms are actually excessive exterior heat syndrome. For cases with vital qi insufficiency, the pathogenic evils fight against defensive qi to cause visceral dysfunctions. The pathogenic evils then transform into heat for further attacks, which may impair nutrient qi to cause the syndrome of dual blaze of qi nutrient aspects. In the advanced stage, the subsided pathogenic evils and the deficient vital qi impair both qi and yin.

15.2 Syndromes Differentiation by TCM

15.2.1 Features of Syndromes

Influenza A (H1N1) usually shows flu-like symptoms, including fever, chills, cough, sore throat, expectoration, general soreness, headache and fatigue. In some cases, diarrhea and/or vomiting occurs. About 10 % cases have no fever and the conditions of some patients may develop rapidly with sudden high fever over 39 °C. Syndromes of pericardial invasion occur, even with yin exhaustion or yang exhaustion, followed by death from syncope and collapse.

15.2.1.1 Syndrome of Wind Heat Invading the Defense

Syndrome of wind heat invading the defense has symptoms of fever and chills or no fever, inflamed throat or throat upset, muscles soreness and fatigue, mild cough, slight red tongue, thin tongue coating or thin greasy tongue coating, and floating pulse.

15.2.1.2 Syndrome of Heat Evil Invading the Lungs

Symptoms include fever, frequent and violent cough, thick yellowish or bloody phlegm, sore throat, thirst, red eyes, nausea, vomiting, abdominal pain, diarrhea, red or purple tongue, yellow or greasy tongue coating and slippery pulse.

15.2.1.3 Syndromes of Dual Blaze of Qi Nutrient Aspects

Symptoms include high fever, cough, shortness of breath, chest distress, or chest distending pain, irritation, even coma and delirium, thirst, red urine, dry stool, red or purple tongue, yellow tongue coating and thready pulse.

15.2.1.4 Syndrome of Right Qi Deficiency and Evils Subsiding

Symptoms include fatigue, weakness, dry mouth, excessive sweating, poor appetite, red tongue, thin tongue coating, thready and weak pulse.

15.2.2 Key Points for Differentiation

Influenza A (H1N1) develops from pathogenic heat evil invading the defense, which belongs to the syndrome of exterior heat and excess syndrome. Then, the heat evil invades the lungs to impair nutrient qi, followed by pathogenic evils subsiding and the vital qi deficient which consumes and impairs yin.
