The drug of choice for syphilis treatment is

Choice A reason: Chlamydia is not the least common of all the major sexually transmitted diseases. In fact, it is the most common bacterial STD in the world, affecting about 131 million people each year. ¹ Therefore, this statement is false and does not need to be emphasized.

Choice B reason: Good handwashing technique is not the best way to prevent chlamydial infections. Chlamydia is spread through sexual contact, not through casual contact or hygiene. The best way to prevent chlamydial infections is to practice safe sex, such as using condoms, limiting the number of partners, and getting tested regularly. Therefore, this statement is misleading and does not need to be emphasized.

Choice C reason: Most people infected with chlamydia are unaware that they are infected. This is because chlamydia often has no symptoms, or the symptoms are mild and easily ignored. This can lead to serious complications, such as pelvic inflammatory disease, infertility, ectopic pregnancy, and increased risk of HIV. Therefore, this statement is true and needs to be emphasized.

Choice D reason: Burning and pain with urination is a frequent symptom of chlamydial infections. However, this symptom is not specific to chlamydia, as it can also occur with other STDs or urinary tract infections. Moreover, not all people with chlamydia experience this symptom, especially women. Therefore, this statement is not very informative and does not need to be emphasized.

Choice A reason: The HPV vaccine can help prevent cervical cancer, as it protects against the most common types of HPV that cause cervical cancer. HPV is a sexually transmitted infection that can infect the cervix and cause abnormal cell changes that may lead to cancer. The HPV vaccine is recommended for both males and females between the ages of 9 and 26.

Choice B reason: The HPV vaccine will not protect you from all types of the virus, as there are more than 100 types of HPV, and the vaccine only covers 9 of them. However, these 9 types are responsible for about 90% of cervical cancers and 80% of anal cancers. The vaccine also does not protect against other sexually transmitted infections, such as chlamydia, gonorrhea, or HIV.

Choice C reason: You will not need to have a booster vaccination each year, as the HPV vaccine is given in a series of 2 or 3 doses, depending on the age of the person. The vaccine provides long-lasting protection, and no additional doses are needed after completing the series.

Choice D reason: You will still need to get a routine cervical exam, as the HPV vaccine does not eliminate the risk of cervical cancer completely. The vaccine does not protect against all types of HPV, and some people may already be infected with HPV before getting the vaccine. Therefore, regular screening with a Pap test and/or an HPV test is still recommended for women aged 21 to 65 to detect any abnormal cells or HPV infection in the cervix.
