6. Which of the following conditions does not describe how infectious diseases spread?
A. Malaria spreads after a mosquito stings an infected person or animal.
B. Cancer is spread through tobacco smoke and poor diet.
C. Influenza is transmitted by a kiss, a handshake, or even close contact with an infected host.
D. The Plague was spread from an infected flea that bites humans
E. HIV/AIDS is transmitted thual contact or sharing needles.
B?
You're right.
To determine which of the conditions does not describe how infectious diseases spread, let's examine each option:
A. Malaria spreads after a mosquito stings an infected person or animal. This is an accurate description of how malaria is transmitted. Mosquitoes can carry the malaria parasite and transfer it to humans or animals through their bites.
B. Cancer is spread through tobacco smoke and poor diet. This option describes how certain lifestyle choices and factors can increase the risk of developing cancer, but it is not related to infectious disease transmission. Cancer is not transmitted from one person to another.
C. Influenza is transmitted by a kiss, a handshake, or even close contact with an infected host. This is an accurate description of how influenza viruses can spread. It can be transmitted through respiratory droplets when an infected person coughs, sneezes, or talks, or by touching surfaces contaminated with the virus.
D. The Plague was spread from an infected flea that bites humans. This is an accurate description of how the bubonic plague, caused by the bacterium Yersinia pestis, spreads. Fleas become infected after biting infected rodents and then transmit the bacteria to humans through subsequent bites.
E. HIV/AIDS is transmitted thual contact or sharing needles. This is an accurate description of how the human immunodeficiency virus (HIV) is transmitted. It can be passed from one person to another through unprotected sexual activity or sharing needles contaminated with infected blood.
Based on the explanations provided, option B ("Cancer is spread through tobacco smoke and poor diet") does not describe how infectious diseases spread. Cancer is not caused by an infectious agent and does not spread from person to person.
