Scientific terminology

Watch this interview with Dr Iain Reeves very carefully. He talks about the scientific terminology used to describe different types of transmission of HIV. After watching, complete the following activity.

Dr Iain Reeves describes four types of tranmission above. Vertical, horizontal, vehicle-borne & vector-borne. Read through the six facts and select the scientific term for transmission you think could occur in each case.

Can you explain why there is no example of vector-borne transmission of HIV?

What other viruses do you know about that are vector-borne?

Some people mistakenly think that HIV can be transmitted by sharing razors, by a mosquito or by sharing a toothbrush with a positive person. How would you explain why this is wrong using scientific terminology?
