Ebola virus shows primarily some non specific flu like symptoms like fever, malaise, muscle weakness etc but as the infection progresses it causes severe bleeding and coagulation abnormalities . When human\'s immune cells encounter these viruses cytokines are released which leads to destructive inflammation. The virus leads to intravascular coagulation in the liver damaging its tissues. Terminal stage of ebola pathogenesis causes fiffuse bleeding and hypotensive shock. Influenza virus when introduced into the respiratory tract or when a healthy individual comes in contact with the respiratory secretions from infected individuals the virus attaches and replicates in the epithelial cells of the upper and lower respiratory tract. This leads to destruction of the lining of the respiratory tract. The viral infection shows flu like symptoms like nasal stuffiness, runny nose, ear ache, cough, breathing difficulties,fever etc. Complications aldo include sinusitis, bronchitis etc. Pneumonia is among one of the more severe complications in which the virus replicates in the alveoli leading to rupture of alveoli and bronchioles. HIV replicates inside the immune cells of the host\'s body. The virus has a glycoprotein gp120 on its durface which fits well with the marker protein called CD4 on the surface of immune cells like macrophages and T helper cells. HIV enters these cells, destroys them and as a result the infected individuals immune system deteriorate and the AIDS patient die of infection that a healthy person can easily fight off. Initially the virus shows influenza like symptoms gollowed by a latency of 8-10 years when it continues to infect the immune cells without showing any clinical symptoms.
