Which describes a way that pathogens can be spread.?

Pathogens can enter the body from body fluids. They can also be transferred by blood via body contact or sharing needles. Pathogens aren't to be messed around with, because they can range from HIV to salmonella to parasites.


Are body fluids and body gases dangerous?

Just about anything can be dangerous if in very large amounts or used for the wrong thing. In these cases, they are not dangerous if they are normal. Body fluids can (sometimes) contain viruses and bacteria which can be spred and therefore dangerous. Body gases can cause discomfort but other than that, they pose no danger.


Can you get AIDS by licking a penis or anus and penetrating the anus with your penis?

HIV, the virus that can lead to AIDS, can be transmitted through unprotected sexual activities, particularly those involving mucous membranes coming into contact with infected bodily fluids like blood, semen, vaginal fluids, or rectal fluids. Engaging in the activities described increases the risk of transmission due to the exchange of bodily fluids and direct mucous membrane contact. Using protection such as condoms can significantly reduce the risk of HIV transmission during sexual activities.


How long can HIV live on the hand or on a body part?

There is some controversy on the exact answer to your question; however per the CDC: "CDC studies have shown that drying of even these high concentrations of HIV reduces the amount of infectious virus by 90 to 99 percent within several hours. Since the HIV concentrations used in laboratory studies are much higher than those actually found in blood or other specimens, drying of HIV-infected human blood or other body fluids reduces the theoretical risk of environmental transmission to that which has been observed--essentially zero. ". In essence then, once the blood is dry, the transmission essentially "goes to zero". The length of time then that HIV can live on the hand or on a body part will vary based on temperature and humidity; but an estimate would be several hours minimum.


Can HIV leave the body?

No, HIV cannot completely leave the body. Once someone is infected with the virus, it remains in their system for life. However, with proper treatment and medication, the virus can be controlled and managed effectively.
