ABSTRAK
Penyakit Ebola disebabkan oleh virus Ebola yang termasuk dalam keluarga virus floviridae. Penyakit ini menyebar melalui kontak langsung dengan cairan tubuh individu terinfeksi. Dalam penelitian ini, dibahas mengenai model matematika transmisi penyakit ebola dengan relapse dan reinfeksi. Penyakit tersebut dimodelkan dengan menggunakan sistem persamaan diferensial biasa berdimensi tujuh. Model ini menunjukkan adanya fenomena backwards bifurcation yang dianalisa dengan memperhatikan perubahan arah pada titik keseimbangan endemik. Eksistensi backward bifurcation pada model penyakit Ebola dikarenakan adanya relapse dan reinfeksi sehingga terdapat titik keseimbangan endemik saat basic reproduction number R0 kurang dari satu. Jumlah total kasus baru individu terinfeksi Ebola meningkat dengan meningkatnya nilai parameter relapse dan reinfeksi.

ABSTRACT
Ebola disease is caused by the Ebola virus which belongs to the floviridae virus family.This disease spreads through direct contact with the body fluids of infected individuals.In this undergraduate thesis, we discussed the mathematical model of Ebola diseasetransmission with relapse and reinfection. This infection is modeled using systemof seven dimensions ordinary differential equation. This model shows the backwardbifurcation phenomenon that is analyzed by considering the direction change in theendemic equilibrium point. The existence of backward bifurcation in the Ebola diseasemodel is due to relapse and reinfection so there is an endemic equilibrium point whenbasic reproduction number R0 is less than one. The total number of new cases ofindividuals infected with Ebola increases with increasing values of the parameters relapseand reinfection.

Although Ebola and similar hemorrhagic fevers have occurred in the past, both the numbers and geographic spread of the 2014-15 West African Ebola epidemic were unprecedented. Ebola and the associated risks drove an improvised, sometimes ineffective, response from political and medical authorities. Fear, rather than rational planning, drove many decisions made at population and leadership levels. Institutions, practices, economies, and governments were all deeply affected by the demands engendered by this emergency. Ultimately, the epidemic revealed serious fault lines at all levels in the theories and practices of global public health. Doctors Without Borders/Medecins sans Frontieres (MSF), as the major provider of medical care to the afflicted, was deeply entangled in many of these issues. From difficult choices made for the care of individual patients to the impact of Ebola on entire health systems, the common thread in each chapter is how fear influenced the political and medical response. Using materials from the MSF archives, this book explores this theme in ten chapters and four eyewitness vignettes. The book examines the epidemic from the perspectives of a wide range of actors from distinct sectors, including a bioethicist, a political scientist, a historian, clinical doctors, policymakers, and anthropologists.
