Yes, it is possible but very rare. The New England Journal of Medicine reported on cases and they were sure that it is possible.

T. cruzi can be transmitted by blood transfusion
Dengue is primarily transmitted through the bite of an infected Aedes mosquito, not directly from person to person. However, if a mosquito bites a person infected with the dengue virus, it can then transmit the virus to other individuals through its bites. In rare cases, dengue can be transmitted through blood transfusions, organ transplants, or from mother to child during pregnancy or childbirth. To prevent dengue, it is essential to control mosquito populations and avoid bites.
Platelet transfusion is generally recommended for severe cases of dengue infection if the platelet count drops significantly and there is bleeding. Blood transfusion may be necessary if there is severe bleeding or if there is a significant drop in hemoglobin levels. Transfusions should only be done under the guidance of a healthcare professional.
Malaria normally spreads by bite of infected mosquitoes. Rarely the disease is transmitted by transfusion of infected blood.
Dengue is primarily transmitted by the bite of a certain type of mosquito (see related link.) Dengue may also be transmitted via infected blood products and through organ donation. Transmission from mother to child during pregnancy or at birth may also occur.
The patient benefits from blood salvage by the elimination of the risk of blood-transmitted virus or blood transfusion reactions.
That's untrue. Yes, you can get gonorrhea through sexual intercourse. No, you can get it through a blood transfusion. No, you can get it through a blood transfusion.

Hepatitis B
Treatment of acute dengue is supportive, using either oral or intravenous rehydration for mild or moderate disease, and intravenous fluids and blood transfusion for more severe cases. Do not use aspirin as it is an anticoagulant.
No because the blood does not have the autism factor.
