Verified step by step guidance

1. Step 1: Understand the key characteristics of sexually transmitted infections (STIs). Some STIs can be asymptomatic, meaning they do not show noticeable symptoms immediately or for long periods.
2. Step 2: Recognize that certain STIs, such as bacterial infections like chlamydia and gonorrhea, can be effectively treated and cured with antibiotics.
3. Step 3: Identify that not all STIs cause noticeable symptoms immediately after exposure; some may remain undetected for a long time, which is why regular testing is important.
4. Step 4: Acknowledge that using condoms is a well-established method to reduce the risk of transmitting many STIs by providing a physical barrier during sexual activity.
5. Step 5: Conclude that the false statement is the one claiming all STIs cause noticeable symptoms immediately after exposure, as this contradicts the asymptomatic nature of many infections.
