Objective: To observe the clinical symptoms after haze exposure and analyze the influences on the respiratory tract. Methods: We conduct prospective study by designing questionnaires about respiratory reaction after haze exposure. We distribute, and collect the questionnaires from 301 subjects, and use statistical software to analyze it. Result and Conclusion: (1) Exposure to haze can lead to a series of respiratory and systemic symptoms. The most common symptoms are cough, little sputum, sneezing and running nose, nasal cavity dryness, nasal congestion, dry throat, dry eyes, itchy eyes. (2) The manifestation frequency of most symptoms in population is positively correlated with the haze concentration. (3) Haze irritates the respiratory tract and causes haze-related cough and respiratory allergy symptoms.
