Question

Sexually transmitted infections (STIs) can be contracted through which of the following ways?

Mr. BALACHANDRA.N · Accepted Answer

## CORE INFORMATION
✓ **Answer**: Option B
## CONCEPT FRAMEWORK
 **Primary Concept**: Transmission of Sexually Transmitted Infections (STIs)
 **Related Topics**:  Bloodborne pathogens, vertical transmission, modes of infection
 **Prerequisites**: Basic understanding of STIs and how they spread.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the ways STIs can be contracted.
  Options include using sterile needles, blood transfusion, mother-to-fetus transmission, and kissing.
**Method & Steps**:
 1. Analyze each option to determine if it's a plausible method of STI transmission.
  Reasoning: STIs are transmitted through direct contact with infected bodily fluids.
  Formula/Rule: None directly applicable, but understanding of disease transmission is key.
 2. Evaluate each option based on the transmission mechanism.
  Working:
  Option A: Using sterile needles is unlikely to transmit STIs because sterile needles are free from pathogens.
  Option B: Blood transfusions from an infected person can transmit STIs because the blood contains the infectious agents.
  Option C: Infected mothers can transmit STIs to their fetuses during pregnancy or childbirth (vertical transmission).
  Option D: Kissing is generally not considered a primary route for most STIs, although some exceptions exist (e.g., herpes simplex virus).
  Key Point:  The most common transmission routes for STIs are sexual contact (vaginal, anal, or oral), and the exchange of bodily fluids.
 3. Identify the correct option(s).
  Result: Option B (blood transfusion from an infected person) is a definite method of STI transmission. Option C (mother to fetus) is also a valid method, but Option B is the most directly related to the question.
  Verification:  Medical literature supports the transmission of STIs through blood transfusions and vertical transmission. 
 ## OPTION ANALYSIS
[A] :x: Using sterile needles does not transmit STIs because they are free of pathogens.
[B] ✓: Transfusion of blood from an infected person can transmit STIs as the infectious agents are present in the blood.
[C] :x:  While an infected mother can transmit STIs to the fetus, this is not the only method listed that is definitively true.
[D] :x: Kissing is generally not a primary route of STI transmission for most STIs.
 ## LEARNING AIDS
 **Common Mistakes**: 
  1.Confusing routes of transmission: Some people might incorrectly think that casual contact or kissing is a major route for most STIs.
  How to avoid: Understand the specific modes of transmission for each STI.
  2.Overlooking vertical transmission:  Failing to consider the transmission of STIs from mother to child.
  How to avoid:  Learn about the different ways STIs can be transmitted, including vertical transmission.
 **Quick Tips**:
  1.Remember that STIs primarily spread through direct contact with infected bodily fluids.
  2.Use mnemonics or other memory aids to learn the common routes of transmission for various STIs.
