Answer:

Syphilis is a sexually transmitted disease

Explanation:

Syphilis is a sexually transmitted infection caused by Treponema pallidum, a spirochaete gram-negative bacterium with various subspecies. This disease is transmitted through direct contact (person to person) by different types of sexual acts. A chancre is an infectious genital lesion that is considered to be the first stage (and symptom) of syphilis. The incubation period of syphilis is 14-21 days. Syphilis can be divided into four stages: primary, secondary, latent, and tertiary. Primary syphilis produces chancres on the genitals, mouth, rectum, etc. Secondary syphilis causes rashes that occur from 2-8 weeks after the chancres. The third (latent) stage is a latent/hidden phase without noticeable symptoms. Finally, the tertiary (late) stage causes large sores within the body that affects the heart, nervous system, etc. The best manner to prevent syphilis is by practicing safe sex (e.g., by using condoms). It has been suggested that syphilis has an estimated transmission rate of 0.5–1.4% per sexual act. Syphilis doesn't have an effective treatment, but this disease can be cured in its early stages with one dose of benzathine penicillin G (administered intramuscularly).

What would you compare red blood cells to? why?

snow_tiger [21]

Explanation:

On a peripheral blood smear, normal RBCs are disc-shaped with a pale-staining central area called the central pallor. When judging red cell size on a blood smear, the classic rule of thumb is to compare them to the nucleus of a small normal lymphocyte. The normal lymphocyte nucleus has an approximate diameter of 8 µm.
