Sexually Transmitted Infections (STIs)
Sexually transmitted infections are diseases which spread from one person to another through sex intercourse with an infected person.
Some sexually transmitted infections are caused by poor hygiene when a person does not wash his or her body and clothes. Sexually transmitted infections can also be called sexually transmitted diseases.
One example of a sexually transmitted disease is:
Acquired Immune Deficiency Syndrome (AIDS)
The word acquired means to get. The word immune comes from the word immunity which means the ability of the body to fight diseases.
Deficiency means lack of something and syndrome means signs and symptoms of disease.
AIDS is caused by a virus called Human Immunodeficiency Virus (HIV).
It spreads mainly through sex with an infected person.
The AIDS virus can also spread from one person to another in different ways.
Activity 3.7
Discuss different ways in which AIDS can be spread from one person to
another.
How AIDS/HIV is Spread
AIDS can be spread from one person to another in different ways:
• Through sex with an infected person.
• Through transfusion of infected blood.
• From an infected mother to her child.
• By sharing sharp instruments with an infected person.
• Through accidents which involve contact of the blood with infected person.
Signs and symptoms of AIDS
The HIV virus destroys the body’s immunity by killing the white blood cells It leaves the body defenceless. This makes the body weak and unable to fight other diseases.
The signs and symptoms of AIDS include:
• Loss of body weight.
• Itchy skin rash.
• White coating in the mouth (oral thrush)
• Prolonged fever.
• Prolonged dry cough.• General body weakness.
How to prevent and control the spread of AIDS
We can prevent the spread of AIDS in the following ways:
• Abstaining from sex until marriage.
• Use condoms during sex.
• Being faithful to your partner (fidelity)
• Avoid sharing sharp instruments with an infected person.
• Through health education.
• Use screened blood for transfusion.• Having an AIDS test with one’s partner before marriage.
Ways of caring for AIDS patients

• Allowing them adequate rest and sleep.
• Washing their clothes and bedding.
• Spending spare time with patients, giving them hope.
• Providing healthy diet.• Providing counselling
Effects of AIDS
• Causes death in many people.

• Leads to imposition of travel restrictions to some countries.
• Leads to misery and hatred among people due to loss of their loved ones.• Causes large scale famine due to lack of enough labour force.
Other Sexually Transmitted Infections STIs and ways to prevent themCarefully study the chart below.
Tuberculosis (TB)
Tuberculosis is an infectious disease that affects the respiratory system. It is caused by a bacteria called micro bacterium.
How tuberculosis is spread
It is spread by breathing in polluted air containing tuberculosis germs.It is also spread through saliva when sharing food with an infected person.
Signs and symptoms of tuberculosis
• Prolonged cough
• Prolonged fever

Prevention and control of tuberculosis
• Immunize children at birth with the BCG vaccine.

The BCG vaccine (bacille calmette guerin) is given to children at birth because the child is not born with immunity that fights against tuberculosis.
The BCG vaccine is injected on the right upper arm of a child at birth, which protects the child throughout life. Some precautions still needs to be taken.Activity 3.8
