AIDS


World AIDS Day

Started on 1st December 1988, World AIDS Day is about raising money, increasing awareness, fighting prejudice and improving education. The World AIDS Day theme for 2009 is 'Universal Access and Human Rights'. World AIDS Day is important in reminding people that HIV has not gone away, and that there are many things still to be done.

According to UNAIDS estimates, there are now 33.4 million people living with HIV, including 2.1 million children. During 2008 some 2.7 million people became newly infected with the virus and an estimated 2 million people died from AIDS.1 Around half of all people who become infected with HIV do so before they are 25 and are killed by AIDS before they are 35.2

The vast majority of people with HIV and AIDS live in lower- and middle-income countries. But HIV today is a threat to men, women and children on all continents around the world.


Definition of AIDS and HIV Infection

AIDS stands for Acquired Immune Deficiency Syndrome. AIDS is a serious condition that weakens the body's immune system, leaving it unable to fight off illness.
AIDS is the last stage in a progression of diseases resulting from a viral infection known as the Human Immunodeficiency Virus (HIV or AIDS virus). The diseases include a number of unusual and severe infections, cancers and debilitating illnesses, resulting in severe weight loss or wasting away, and diseases affecting the brain and central nervous system.

There is no cure for HIV infection or AIDS nor is there a vaccine to prevent HIV infection. However, new medications not only can slow the progression of the infection, but can also markedly suppress the virus, thereby restoring the body’s immune function and permitting many HIV-infected individuals to lead a normal, disease-free life.

Causes and Risk Factors of AIDS and HIV Infection

AIDS is transmitted via three main routes:
The most common mode of transmission is the transfer of body secretions through sexual contact. This is accomplished through exposure of mucous membranes of the rectum, vagina or mouth to blood, semen or vaginal secretions containing the HIV virus.
Blood or blood products can transmit the virus, most often through the sharing of contaminated syringes and needles.
HIV can be spread during pregnancy from mother to fetus.
You cannot get AIDS/HIV from touching someone or sharing items, such as cups or pencils, or through coughing and sneezing. Additionally, HIV is not spread through routine contact in restaurants, the workplace or school. However, sharing a razor does pose a small risk in that blood from a minor nick can be transmitted from one person to another.

What signs and symptoms can occur if thyroid function is affected?

Thyroid gland: A gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and the rate at which food is converted into energy. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions (metabolism) in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea (windpipe). It has the shape of a butterfly: two wings (lobes) attached to one another by a middle part. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH), which is produced by the pituitary gland, acts to stimulate hormone production by the thyroid gland. The thyroid gland also makes the hormone calcitonin, which is

Common diseases linked to vitamin D deficiency

Sunlight is that the body's main supplier of Vitamin D that is critical for sturdy bones and teeth. Vitamin D is in virtually each tissue, therefore, it's vital for the health of the entire body.

Thyroid - Hypothyroid - Meaning - Causes - Symptoms - Treatment

What is Hypothyroid? Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Causes About three percent of the general population is hypothyroidic. Factors such as iodine deficiency or exposure to Iodine can increase that risk. There are a number of causes for hypothyroidism. Iodine deficiency is the most common cause of hypothyroidism worldwide. In iodine-replete individuals hypothyroidism is generally caused by Hashimoto's thyroiditis, or otherwise as a result of either an absent thyroid gland or a deficiency in stimulating hormones from the hypothalamus or pituitary.
