This document discusses various health topics including what is health, hepatitis, thyroid, AIDS, rabies, and tuberculosis. It defines health as a state of complete physical, mental and social well-being according to the WHO. Hepatitis is inflammation of the liver which can be self-limiting or progress to scarring and cirrhosis, with the most common causes being viruses A-E. The thyroid gland regulates metabolism and is located in the neck, and thyroiditis can cause alternating hyperthyroidism and hypothyroidism. AIDS is transmitted through sexual contact, body fluids and from mother to child, but not through feces or vomit unless contaminated with blood. Rabies causes brain inflammation and symptoms occur 1-12
5. What Is Health ?
Health is the level of functional or metabolic efficiency of
a living organism
In humans, it is the general condition of a person's mind and
body, usually meaning to be free from illness, injury or pain
The World Health Organization (WHO) defined health in its broader
sense in 1946 as "a state of complete physical, mental, and
social well-being and not merely the absence of disease or infirmity."
9. Hepatitis
Hepatitis is a medical
condition defined by the
inflammation of the liver and
characterized by the
presence of
inflammatory cells in
the tissue of the organ. The
condition can be self-limiting
(healing on its own) or can
progress
to fibrosis(scarring)
and cirrhosis
Viral hepatitis:-
The most common causes of viral hepatitis are the five unrelated
hepatotoxic viruses hepatitis A, hepatitis B, hepatitis C, hepatitis
D (which requires hepatitis B to cause disease), and hepatitis E
10. Thyroid
The thyroid gland is found in
all vertebrates. In fish, it is
usually located below the gills
and is not always divided into
distinct lobes. However, in
some teleost's, patches of
thyroid tissue are found
elsewhere in the body,
associated with the kidneys,
spleen, heart, or eyes
There are two types of thyroiditis where initially
hyperthyroidism presents which is followed by a period
of hypothyroidism. These are Hashimoto's thyroiditis and
postpartum thyroiditis
11. Aids
HIV is transmitted by three main routes: sexual
contact, exposure to infected body fluids or tissues,
and from mother to child during pregnancy, delivery,
or breastfeeding There is no risk of acquiring HIV if
exposed to feces, nasal secretions, saliva, sputum,
sweat, tears, urine, or vomit unless these are
contaminated with blood. It is possible to be co-infected
by more than one strain of HIVa condition
known as HIV super infection
12. Rabies
Rabies come from Latin rabies is
a viral disease that causes
acute inflammation of the brain in
humans and other blooded animals. The
time period between contracting the
disease and the start of symptoms is
usually one to three months; however it
can vary from less than one week to
more than one year
Vaccinating dogs, cats, rabbits, and ferrets against rabies
Keeping pets under supervision.
Not handling wild animals or strays
Not handling wild animals or strays
Contacting an animal control officer upon observing a
wild animal or a stray, especially if the animal is
acting strangel
13. Tuberculosis
Tuberculosis typically attacks the lungs,
but can also affect other parts of the body.
It is spread through the air when people
who have an active TB infection cough,
sneeze, or otherwise transmit respiratory
fluids through the air. Most infections do
not have symptoms, known as latent
tuberculosis. About one in ten latent
infections eventually progresses to active
disease which, if left untreated, kills more
than 50% of those so infected.
