Therefore, there are hundreds and thousands of communicable diseases in this world, but to make it short, the diseases that were going to be included are common diseases in America. The flu, also known as influenza, is a disease that transmitted through coughing and sneezing, mostly happen during the winter season. People get the flu by breathing in the tiny wet droplets from a person’s coughs or sneezes, or by touching objects that contain these drops and touching any body parts. Also, a person with a weak immune system can spread the flu for a longer time period than someone with a healthier immune system.

The mechanisms by which the flu cause in humans is believed to be the obstruction of ACTH, known as adrenocorticotropic hormone, triggering low cortisol levels. The process that enables the flu to enter cells is the cleavage viral of hemagglutinin protein by one out of several human proteases. The structure of hemagglutinin can only found in the throat and lungs by proteases, allowing the viruses, not to infect other tissues in the body. However, hemagglutinin, yet, can permit the virus to spread throughout the body. Viral hemagglutinin protein is responsible for processing both strain infect and where human respiratory tract strain will bind. The strains are easily transmitted between people who had hemagglutinin proteins that bind in an upper part of the respiratory tract to receptors, such as in the nose, throat, and mouth.

Another infectious disease is called Hepatitis B. Hepatitis B is a virus that causes damage to the liver, and it can be spread from mother to infant during childbirth through blood and bodily fluids. Developing Hepatitis B depends on how well your immune system reacts to the infection, which means that a person who has a weak immune system, are at a higher risk of developing the infection after being exposed. However, people who are exposed to the infection may not have any signs or symptoms, but others may experience symptoms similar to the flu, such as a fever, fatigue, loss of appetite, nausea, and vomiting.

Hepatitis B hinder the functions of the liver by reproducing in hepatocytes, bind to the cell domain of viral surface antigen and by endocytosis. But viral DNA and proteins had also been transmitted in cellular receptors, existing in extrahepatic cells. During Hepatitis B infection, the immune response causes hepatocellular damage and viral clearance. Cytotoxic T lymphocytes (CTLs), destroy Hepatitis B infection by killing infected cells and resulting antiviral cytokines.

Primary cells that target HIV infections includes, principally blood monocytes and tissue macrophages, T-lymphocytes, natural killer (NK) lymphocytes, dendritic cells, hematopoietic stem cells, microglial cells in the brain, gastrointestinal epithelial cells, and etc.
