HEP B, C: Hepatitis b and c are blood born viruses. Transmission is through direct contact with blood or secretions from an individual who carries the active virus . Sex , shared needles, exchange of fluids from other contacts with enough inoculum may cause infection. Malaria is carried by a mosquito who injects it from their bite. They are the vector but don't cause that illness.
Dr. Larry Lutwick

Wrong word: Mosquito bites transmit malaria which is caused by a parasite. Hbv and hcv are caused by viruses transmitted by blood and certain body fluids.
