THE PREVALENCE OF VECTOR BORNE DISEASES IN TAMPIN HOSPITAL , NEGERI SEMBILAN GANGA DEVI A/P B. SINNIAH UNIVERSITI SAINS MALAYSIA 2018 THE PREVALENCE OF VECTOR BORNE DISEASES IN TAMPIN HOSPITAL , NEGERI SEMBILAN by GANGA DEVI A/P B. SINNIAH Thesis submitted in fulfilment of the requirements for the degree of Master of Sciences July 2018 ACKNOWLEDGEMENT This author is very grateful to GOD ALMIGHTY for without His grace and blessings, this study would not have been possible. My deepest appreciation to my supervisor, Associated Professor Dr. Zary Shariman Yahya, for his excellent guidance, his critical insights, motivation and his patience, willingness of time in sharing knowledge. He was extremely encouraging and instrumental in developing various ideas and arguments of this thesis. Thanks a lot Dr Zary Shariman, for giving me chances as a part time Master Student under your supervision. I sincerely thank the Director of Tampin Hospital, Dr Hajjah Hatijah Bt Hj Mohd Tan for her guidance and encouragement in carrying out this project work. I also wish to express my gratitude to the staffs at Tampin Hospital who have rendered their help during the period of my study. I would like to convey my gratefulness to all my friends, Rajiv and Azirah for their support and help during my experiment in laboratory. The skills and knowledge which I have gained throughout my experiment I perceive as very valuable component in my future development. Special thanks to the practical students in Lab 418 for inspiring and encouraging me as I was an older student among them. Finally, I would like to acknowledge with gratitude, the support and love of my husband and children, my mother, brothers and also sisters. They all kept me going, and this thesis would not have been possible without them. ii TABLE OF CONTENTS ACKNOWLEDGEMENT………………………………………….…... ii TABLE OF CONTENTS……………..………………………………… iii LIST OF
