| ObjectiveAccording to result of the infectious diseases surveillance of the international travellers in Yantai port from2006to2010, to investigate the main diseases that affect the health of international tralellers, and find out the prevalence of the infectious diseases, and explore the epidemical trend of these diseases, providing a scientific basis for preventing and surveillance of infectious disease and health interventions in port, research on the quarantine countmeasure for new epidemic situation.MethodAnalyze the information that already known by using the descriptive epidemiological methods, analyze the occupation constituent ratio of the international travellers at Yantai port in the last five years, analyze the trend and distribution of the infectious disease that affect the international travellers, analyze the distribution of the most common disease, including syphilis, pulmonary tuberculosis, AIDS and viral hepatitis, among different age and occupation of the travellers, discuss the existing problem in surveillance of the infectious diseases at frontier port and try to put forward the solusion and suggestion. Find effective quarantine countermeasure by analyzing the new traits and trend of international infectious diseases. Result(1) The total number of travellers at Yantai port from2006to2010that suffered the serveillance is66049,414case of infectious diseases were found, and detection rate was626/10million, the main infectious diseases were AIDS, syphylis, pulmonary tuberculosis and viral hepatitis.(2) There is no significant differences among the number of travellers from2006to2010, except decreation in2009for the international finacial crisis. The purpose of the travellers including labor service abroad(32.6%), seaman(24.8%), overseas study(12.5%), travel or visit relative(8.13%), bussiness personnel(6.31%) and official personnel(6.06%).(3) The detective rate of the infectious diseases was in doward trend from2006to2010, the highest prevalence rate was the viral hepatitis, about411/10milion, and syphylis(153/10million), pulmonary tuberculosis(48/10million), HIV infection(14/10million) in turn.(4) The detection rate of every infectious diseases, male was higher than that of female, the possible reason why gender affect the detection rate was that male was the main body of social activity, and frequently communicate with others, have more chance to expose themselves to various source of infection, so the prevalence rate of male is higher than that of female.(5) The detection rate of international travellers from China and other country was625/10million and639/10million, and there is no statistically significant difference.(6)9case of HIV infector was found during these5years,5of these case was the seafarers, the constituent ratio was55.6%. The cases distribute from28to 56years old and the average age was39.33±9.46. The main route of transmission was sex.(7)101case of syphylis have been found, including7lcase of male and30case of female case, distributed from19to85, the average age was36.0±11.3. Most of the case was young adult from20to40years old. The infection rate of the travellers from China and foreign country was139/10million and244/10milion, and the difference was statistically significant.(8)32cases of pulmonary tuberculosis have been found during2006to2010, and the detection rate was48.45/10million. The labor service people have the highest constituent ratio(40.6%). The business personnel have the highest detection rate(120.05/10million), higher than the overseas study students(60.5/10million) and labor service people (60.3/10million), but there is no statistically significant different. Most of the cases distribute in20to30years old(46%), and30to40(22%),40to50(16%), under20(13%) in turn, the different between Chinese and foreigners are statistically significant (x2=4.694, P<0.05).(9) The detection rate of hepatitis is always high from2006to2010, and272cases have been found, constitute65.7%of all the infectious disease case. The detection rate was411/10million. Business personnel and seafarers have the highest detection rate, the different between Chinese and foreigners has no statistically significant (x2=2.311, P>0.05).Conclusion:(1) The infectious rate of the infectious diseases was in downward trend, and the diseases that affect the health of international travellers were viral hepatitis, syphylis, pulmonary tuberculosis and AIDS. (2) There are many problems existing in the surveillance of infectious disease at frontier port, for example the quarantine inspection and the follow-up management doesn’t work well, and the laws and regulations were imperfect. The quarantine department should take effective measure to complete the system of infectious disease surveillence, and take responsibility to keep the frontier port free from the infectious disease.(3) Effective and perfect quarantine model should be established while the infectious disease is prevalent all over the world. |
