HIV is transmitted through certain bodily fluids like semen, blood, vaginal fluids and breast milk. Infection only takes place when the bodily fluids of an infected person enters the blood stream of another person. The main route of HIV is unprotected sexual intercourse between men and women. HIV can also be transmitted through sharing needles and syringes with the infected person as well as by unsterile body piercing or tattooing. Also, is it can be transmitted from a mother to her child. According to researchers blood transfusions and blood products of pre 1990s can also lead to the transmission of HIV.
In order to explain the difference between HIV and AIDS it is to simply understand that an individual cannot catch AIDs but he can catch HIV. When an individual is infected by HIV this does not necessarily mean that he is suffering from AIDS but if it is left untreated it can affect the immune system and can progress to AIDS.
AIDS is the result of the destruction of immune system by HIV. The immune system fights off infections and other diseases. When the immune system is defected, an individual can suffer from life threatening diseases and cancer. HIV affects and destroys the disease fighting cells of the immune system. The body is then left with weakened defence against disease.

HIV stands for Human Immunodeficiency Virus. The virus attacks an individual’s immune system. An individual who is affected by HIV or has positive HIV can live for many years without becoming ill and may not even show symptoms. However, during this time the HIV remains in the body and damages the immune system and the person remains infectious. The individual is able to spread the virus if some basic precautions are not taken. HIV can damage the immune system in such a way that infections may began to occur because of the weakened immune system. When one acquires various viruses due to weakened immune system the person then suffers from AIDS or Acquired Immune Deficiency Syndrome. In this there is a collection of illnesses.
Two of the most common symptoms of hyperthermia include heat stroke and heat exhaustion. Heat exhaustion takes place when a person may become thirsty, giddy, weak, uncoordinated, nauseated and is sweating profusely. The body temperature tends to be normal and the pulse is raised or normal. Also, usually in heat exhaustion the skin is either cold or clammy.
On the other hand, heat stroke can be life threatening and a person can also die. A person who has heat stroke, his body temperature is above 104 degrees Fahrenheit. Other symptoms include confusion, bizarre behaviour, faintness, strong and rapid pulse, staggering, and possible delirium or coma. Also high body temperature can lead to irreversible brain damage.

· Cholesterol is the precursor molecule in the various intracellular biochemical pathways.
· Cholesterol is the main component of the bile and helps your body with the digestion of the fats in the body.
· Cholesterol is the important precursor for the production of vitamin D and steroid hormones in your body.

Allergies are common and are usually not life threatening. But there are cases of anaphylaxis which is a severe allergic reaction and needs immediate medical treatment.
Children who have mild allergy will have symptoms like watery and runny eyes, runny nose, sneezing, nasal congestion, itch rash or hives. These symptoms may not be serious but may become severe if a child has a history of asthma or severe allergic reaction.
A person is tend to suffer from severe allergy which is also called anaphylaxis. The symptoms include difficulty in breathing, hive, swelling of the throat, face, lips or tongue, wheezing, hoarseness, pale or flushed skin, sweating, abdominal pain, low blood pressure, nausea and dizziness or fainting.
Just because an individual is coughing, wheezing or having difficulty in breathing, this does not mean that he suffers from asthma. There are several other diseases that have the same symptoms as asthma. Conditions that mimic asthma include sinusitis which is another name of sinus in which there is inflammation or swelling of sinuses. Often sinus and asthma coexist. Myocardial ischemia is another condition in which there is inadequate blood flow to the muscle tissue of the heart. Symptoms may include heart pain but also shortness of breath. Another disease called gastroesophageal reflux disease which is also known as GERD in which stomach content and acid flows back to the oesophagus and causes frequent heartburn. Heartburn can also cause asthma symptoms.

The drugs that bring you relief when you are dying with pain are called the anti-inflammatory medications or non-steroidal anti-inflammatory drugs. But, choosing an effective anti-inflammatory medication requires the understanding of the following:
- The first thing that you should know is how effective an anti-inflammatory medication will be on you.
