NOTE

SEXUALLY TRANSMITTED INFECTIONS (STIS)

Sexually Transmitted Infections (STIs) are infections spread through sexual contact. Examples includes: Chlamydia, Gonorrhea, Syphils, HIV/AIDS, Herpes (HSV-1 and HSV-2)

Sexually transmitted infections (STIs) are typically transmitted through unprotected sexual contact. Common signs and symptoms include genital sores, discharge, and pain during urination. Prevention involves safe sex practices, such as condom use, and vaccination where available. Regular STI testing and communication with partners are crucial. Control measures include prompt treatment, partner notification, and public health education to reduce transmission risk.

HIV and AIDS

HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, weakening the body's ability to fight infections and diseases. AIDS (Acquired Immunodeficiency Syndrome) is the final stage of HIV infection when the immune system is severely damaged.

Mode of Transmission

1. Sexual Transmission:

   - Unprotected vaginal, anal, or oral sex with an infected person.

   - Use of contaminated sex toys.

2. Bloodborne Transmission:

   - Sharing of needles or syringes among injecting drug users.

   - Receiving contaminated blood or blood products.

3. Mother-to-Child Transmission:

   - During childbirth.

   - Through breastfeeding.

4. Occupational Exposure:

   - Accidental exposure to infected blood or body fluids in healthcare settings.

 Signs and Symptoms

1. Early Stage: Flu-like symptoms (fever, fatigue, sore throat), Swollen lymph nodes.
2. Asymptomatic Stage: No noticeable symptoms.
3. Advanced Stage (AIDS): Persistent fever, night sweats, Weight loss, Chronic diarrhea, Opportunistic infections and cancers.

Prevention of HIV/AIDS

1. Safe Sex Practices:

   - Consistent and correct condom use.

   - Limiting sexual partners.

2. Needle Exchange Programs:

   - Providing clean needles to injecting drug users.

3. Pre-Exposure Prophylaxis (PrEP): Medication for individuals at high risk to prevent HIV transmission.
4. Treatment as Prevention: Early initiation of antiretroviral therapy (ART) to suppress viral load.
5. Mother-to-Child Prevention:

   - Use of ART during pregnancy and childbirth.

   - Safe alternatives to breastfeeding if possible.

 Control of HIV/AIDS

1. Early Detection and Treatment:

   - Regular HIV testing for early detection.

   - Immediate initiation of ART upon diagnosis.

2. Public Awareness:

   - Education to reduce stigma and discrimination.

   - Promoting awareness about preventive measures.

3. Support Services: Access to healthcare, counseling, and support groups.
4. Global Initiatives: International efforts to ensure access to treatment and prevention globally.

EVALUATION: 1. What is STIs

2. Identify 3 preventive majors for STIs.
3. How HIV/AIDS be prevented
