Identifying Sexually Transmitted Diseases

A sexually transmitted disease (STD), also known as a sexually transmitted infection (STI), is an illness passed from one person to another through sexual contact. This contact can include vaginal, anal, or oral sex.

Disease Transmission Analysis

Let's examine the options provided:

• Protein Energy Malnutrition: This is a nutritional deficiency disease, not transmitted sexually.
• Acquired Immuno Deficiency Syndrome (AIDS): This disease is caused by the Human Immunodeficiency Virus (HIV). HIV is primarily transmitted through sexual contact, as well as through blood and from mother to child. Therefore, AIDS is a sexually transmitted disease.
• Diabetes: This is a chronic metabolic disorder affecting blood sugar levels. It is not transmitted through sexual contact.
• Cancer: While certain viruses that can be sexually transmitted (like Human Papillomavirus - HPV) can cause specific types of cancer, cancer itself is not directly transmitted during a sexual act.

Conclusion

Based on the analysis, Acquired Immuno Deficiency Syndrome (AIDS) is the human disease among the options that can be transmitted during a sexual act.
