Can hepatitis B be transmitted by mosquito?
When a mosquito bites, it injects saliva through one channel. However, the blood it sucks as a meal flows in a completely separate channel and only in one direction, toward the mosquito. So the answer therefore is that it is biologically unlikely for mosquitoes to transmit Hepatitis B .

Why hepatitis B is not curable?

What is the life span of hepatitis B patient?
The estimated carrier life expectancy is 71.8 years , as compared to 76.2 years among noncarriers (Figure 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.
