WHO stands for World Health Organisation.
Explanation:
The World Health Organization is a specialized agency of the United Nations that is concerned with international public health. It was established on 7 April 1948, headquartered in Geneva, Switzerland.

Rabies is also called Hydrophobia.
Explanation:
Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Early symptoms can include fever and tingling at the site of exposure.

BCG stands for Bacille Calmette Guerin.
Explanation:
An effective immunization against tuberculosis. BCG stands for Bacille Calmette Guerin. BCG is a weakened (attenuated) version of a bacteria called Mycobacterium bovis which is closely related to Mycobacterium tuberculosis, the agent responsible for tuberculosis.

Diseases are of two main kinds : Congenital and Immunity.
Explanation:
immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune disease.

HIV stands for Human Immunodeficiency Virus.
Explanation:
HIV is a virus that attacks the immune system. AIDS refers to a set of symptoms and illnesses that occur at the very final stage of HIV infection. HIV is a virus that attacks the immune system, which is our body’s natural defence against illness.

Health is state of well being physically Mentally and socially.
Explanation:
All the three aspects of health, social mental and physical are equally important for wellbeing of human being.

The two important contributory causes of diseases are Under nourishment and Genetic make up.
Explanation:
The diseases are caused by lack of nutrients or passed on from heredity from parents to off springs. The diseases caused due to lack of nutrition are Scurvy, Rickets. Some genetic disorders are inherited from the parents, while other genetic diseases are caused by acquired changes or mutations in a pre-existing gene or group of genes. The genetically acquired disease are Down syndrome and Cystic fibrosis.

The virus that causes acquired immune deficiency syndrome (AIDS) parasitizes Helper T-Cells.
Explanation:
T-cells are targeted as the AIDS parasitizes the CD4+ molecules on their surface. Our body fights back the HIV infections producing another 2 billion cells to replace the infected ones stabilizing the T-cells count temporarily. Yet from day one, the T-cells fight a losing battle. Although HIV target T-cells and other cells in the body, HIV thrives mainly in the lymph nodes and the other immune parts of our body.

Any organisms capable of producing a disease is called Pathogen.
Explanation:
A pathogen or infectious agent is a biological agent that causes disease or illness to its host. pathogens can infect unicellular organisms from all of the biological kingdoms.

Diseases are of two main kinds : Congenital and Acquired.
Explanation:
Acquired heart disease is heart disease that develops after birth. There are several types of congenital heart disease. Example is AIDS and Amebiasis.

Malaria is spread by Anopheles which breed in Stagnant water.
Explanation:
Malaria disease is transmitted through the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite. When this mosquito bites, the parasite is released into your bloodstream. Once the parasites are inside the body, they travel to the liver, where they mature. After several days, the mature parasites enter the bloodstream and begin to infect red blood cells. Within 48 to 72 hours, the parasites inside the red blood cells multiply, causing the infected cells to burst open. The parasites continue to infect red blood cells, resulting in symptoms that occur in cycles that last two to three days at a time.

Diseases present from the birth are called Congenital.
Explanation:
A congenital disorder, also known as a congenital disease, deformity, birth defect, or anomaly, is a condition existing at or before birth regardless of cause. Of these disorders, those characterized by structural deformities are termed "congenital anomalies" and involve defects in a developing fetus.

BCG vaccine gives considerable protection against tuberculosis.
Explanation:
T-cells are targeted as the AIDS parasitizes the CD4+ molecules on their surface. Our body fights back the HIV infections producing another 2 billion cells to replace the infected ones stabilizing the T-cells count temporarily. Yet from day one, the T-cells fight a losing battle. Although HIV target T-cells and other cells in the body, HIV thrives mainly in the lymph nodes and the other immune parts of our body.

Cholera is caused by Bacterium but malaria is caused by Protozoan.
Explanation:
Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic protozoans belonging to the Plasmodium type.

The organism which spread the disease from an infected to a healthy person is called Vector.
Explanation:
Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new host during their subsequent blood meal. Mosquitoes are the best known disease vector. Others include ticks, flies, sand flies, fleas, triatomine bugs and some freshwater aquatic snails.

Interferons are anti Viral proteins.
Explanation:
Interferons (IFNs) are a group of signalling proteins made and released by host cells in response to the presence of several pathogens, such as viruses, bacteria, parasites, and also tumor cells. Interferons are named for their ability to "interfere" with viral replication by protecting cells from virus infections.

Infectious diseases are caused by Micro organisms.
Explanation:
Infectious diseases are caused by microorganisms such as viruses, bacteria, fungi or parasites Microorganisms that cause disease are collectively called pathogens. The disease are flu, influenza, AIDS etc.
