Objective To explore the relationship between the number of influenza-like cases with the daily average temperature,daily maximum temperature,daily minimum temperature and daily temperature difference,as well as the relationship between the daily average temperature and TCM symptoms in Beijing in winter and spring of 2016/2017. Methods A cross-sectional survey method was used to collect the influenza-like illness numbers and TCM symptoms in outpatient clinics of 4 hospitals of Beijing from November 14,2016 to February 28,2017,the correlation between the number of their daily incidence and four temperature factors was analyzed respectively,and according to the daily average temperature changes,the cases were divided into rising daily average temperature group and declining daily average temperature group,Chi-square test was used to compare the difference of TCM symptoms between the two groups. Results A total of 1226 influenza-like cases were collected,of them,the male accounted for 45. 4%,the female for 54. 6%,and the age was 40. 0 ± 16. 3 years old including 740 positive cases（ 60. 4%）; there was negative relationship between the daily incidence and the daily average temperature,the daily maximum temperature,and daily minimum temperature,but positive relationship with the daily temperature difference,and there was no difference in TCM symptoms between TCM syndromes of influenza-like cases in rising daily average temperature group and declining daily average temperature group. Conclusion The number of influenza-like cases can be changed differently under the influence of temperature,it may be related to the changes of human activities caused by temperature changes; there is no obvious difference between the symptoms of influenzalike cases caused by rinsing and declining of daily average temperature as all of them have the syndromes of fever,cough and sore throat. The differentiation of it is wind-heat syndrome and falls into the category of "wind febrile".
