AIDS & Hepatitis B are worst enemies!

The two big concerns for the World Health Organisation (WHO) are the two viruses known Hepatitis B & the HIV AIDS as 33.3 million people worldwide are living wit HIV & more than 2 billion people 've been infected with Hepatitis B virus.

A little more on AIDS...
While 2.6 million are infected with HIV, the WHO estimated 1.8 million annual deaths due to AIDS. It's a disease of the human immune system that is caused by the human immunodeficiency virus (HIV). The virus damages the immune system & leaves the patients miserable. AIDS is transmitted through direct contact of mucous membrane or the bloodstream with a bodily fluid containing HIV such as semen, blood, vaginal fluid, preseminal fluid & breast milk. It can be transmitted through anal, vaginal or even oral sex, blood transfusion, contaminated needles & razors, exchange between mother & baby during pregnancy, childbirth.

According to the 2009 UNAIDS report, 60 million 've been infected with the deadly virus, 25 million patients 've died & 14 million children 've become orphan in southern Africa alone due to the disease. Around 2.4 million people are estimated to 've been infected wit HIV in India.

The virus was first identified by the US Centers for Disease Control & Prevention in 1981. Since then millions 've been tested positive for the disease. The disease is described as deadly because there is no known cure or vaccine has been invented. The treatment can only the mortality & the morbidity of HIV infection.

The drugs are expensive & the medication is not available in most of the countries. As the prevention is better than cure, the WHO is promoting some awareness programs in order to minimize the spread of the virus.

A little more on Hepatitis B...
The transmission of the Hepatitis B virus is hundred times more dangerous than HIV. It is caused by virus (HBV) which infects the iver of hominoidea, including humans & causes an inflammation called Hepatitis. It is described as epidemic in parts of Asia & Africa & endemic in China. More than 2 billion people 've been infected with the Hepatitis B virus to date.

The virus gets transmitted due to infectious blood or fluids such as semen & vaginal fluids. However, the disease cannot be spread by casual contact like holding hands, sharing eating utensils or drinking glasses, breast-feeding, kissing, hugging, coughing or sneezing.

Illness such as inflammation, vomiting & jaundice are caused by acute Hepatitis B, while the chronic disorder causes liver cirrhosis & liver cancer. However, the infection can be prevented by vaccination. The disease is the biggest concern for India as more than 40 million people are infected with the deadly disease in the country & it is hundred times more infectious than the HIV AIDS.

Hence AIDS & Hepatitis B are referred to as the worst enemies of mankind in terms of diseases!
