AIDS stands for Acquired immune deficiency syndrome. I've always wondered what exactly occured once you received this fatal disease. Well, after a bit of reseaching, I found out that the AIDS virus progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors.

HIV is transmitted through contact of the membrane called the mucuos membrane, or the bloodstream containing bodily fluid. Fluids such as blood, semen, and vaginal fluid are the most common. Before i just thought that AIDS was another STD ( Sexually Transmitted Disease), but i realize that it is not. Its a virus that shuts down your immune system until you are no more.

HIV, was orignated in west central Africa, while the first signs of AIDS were noticed by the U.S. It's cause was HIV.


Mononucleosis, also known as the kissing disease or mono. The virus usually only infects teens or young adults, between the ages of 15 and 25mononucleosis40x02.jpg. Mono is caused by the Epstein-Barr virus. It is also a type of Herpes, and 90% of adults will encounter the virus through some point of there lives. Kind of scary to think about that. Classic symptoms of the virus is sore throat, fatigue, weight loss, and fever. Mono is a very highly contagious virus so don't be sharing any water bottles with Riley if he is showing all the symptoms i've mentioned here.

Mononucleosis has no cure, your body will fight of the virus eventually in a couple weeks. Just remember to drink lots of fluids and get some rest and you'll be as good as new in no time!

Lou Gehrig Disease.

Yankees!! Lou Gehrig's disease refers to a disorder called amyotrophic lateral sclerosis (ALS). In the United States, ALS is often called Lou Gehrig's disease because of the New York Yankees' star Lou Gehrig, who was diagnosed with ALS in the 1930s. Lou Gehrig's disease damages spinal cord pathways and motor
neurons, which are important parts of the body's neuromuscular system. The neuromuscular system enables our bodies to move and is made up of the brain, nerves, and muscles. Things that we do every day, like breathing, walking, running, and over all, moving, are all controlled by the neuromuscular system.

Lou Gehrig's disease causes these motor neurons in the brain and spinal cord to shrink and disappear, so that the muscles no longer receive signals to move. As a result, the muscles become smaller and weaker. The body then becomes partially paralyzed, which means certain muscles no longer work. However, someone with ALS, even at an advanced stage, can still see, hear, smell, and feel touch. The nerves that carry feelings of hot, cold, pain, pressure, or even being tickled, are not affected by Lou Gehrig's disease. Lou eventually lost his life three years after finding out he had the disease. Which is the average after being diagnosed.

West Nile virus

West Nile is a virus that is found and tranmitted through mosquitos. Usually can be found in temperate and tropical regions, west nile mainly infects birds, but now infects humans, horses, dogs and even cats. The capsid is contained within a host-derived membrane altered by two viral glycoproteins.

The West nile virus has three stages of infectious symptoms, usually lasting anywhere from one to two weeks long. The most painful stage would be the febrile stage which is followed by 2 to 8 days of headaches, chills, excessive sweating, dizziness, and pains of the joints. Most symptoms are similar to ones of the influenza or flu. In the U.S in 2007, there were a confimed number of 3,630 cases of west nile, which would lead me to believe its a pretty common disease in North America as of late.The virus is transmitted through mosquito vectors, which bite and infect birds. The birds are amplifying hosts, developing sufficient viral levels to transmit the infection to other biting mosquitoes which go on to infect other birds (in the Western hemisphere the American robin and the American crow are the most common carriers) and also humans. The infected mosquito species vary according to geographical area
