Answer:
HIV and Influenza
Step-by-step explanation:
Communicable diseases are able to be passed on from person to person through different means. HIV can be transmitted by having unprotected sex with an infected person or if you are infected, while influenza is transmitted in various ways, most commonly by airborne respiratory droplets from coughs or sneezes. Whereas color blindness is transmitted by genetic means and cannot be passed on in any other way. As for diabetes, it's caused by abnormally high insulin or abnormally low insulin depending on the type of diabetes and cannot be transmitted through any means.
