Question 1. (1): Distinguish among pathogenic, deficiency, hereditary and physiological diseases. Include at least one example of each.
A pathogenic or an infectious disease is caused by an external infectious agent or pathogen such as viruses, bacteria, parasites and fungi. These pathogens are found in water, soil and air and a human body can be infected from drinking, eating or touching something infected with germs. Example: Pneumonia
A deficiency disease is caused by a deficiency of vital nutrients in the diet, especially a mineral or vitamin. The disease could be as a result of an insufficient intake of nutrients, their digestion, their absorption or their utilization within the body.
Example: Scurvy
Hereditary diseases or genetic
The chances of transmitting the disease to the child are higher in women in advanced stages of the disease. Breast feeding increases the risk of transmission by 10-20%

Note: HIV is not transmitted by handshakes or other casual non-sexual contact, coughing or sneezing, or by bloodsucking insects such as mosquitoes.

Control
There is currently no publicly available HIV vaccine or cure for HIV or AIDS. The only known methods of prevention are based on avoiding exposure to the virus or, failing that, an antiretroviral treatment directly after a highly significant exposure, called post-exposure prophylaxis (PEP). PEP has a very demanding four week schedule of dosage. It also has very unpleasant side effects including diarrhea, malaise, nausea and fatigue.

Genital
It is passed from one person to another by close, direct contact. The most common mode of transmission is through vaginal, anal or oral sex. When somebody becomes infected with HSV, it will generally remain dormant.

Keep in mind that triggers vary from person to person, so you must try to recognize the triggers that affect you the most.

The mate or partner should be notified immediately when you find out you have the virus. Also, use all precautionary measures and protection when having intercourse..

Look for foods high in antioxidants with essential nutrients for good health. You might also try herbal tea. Some herbs and supplements
