Transmission of HIV in a healthcare setting is extremely rare. The health care professionals are supposed to follow the infection control procedures in their health care settings for infection control. These procedures are called universal precautions for infection control. They are designed to protect both patients and healthcare professionals from the transmission of blood-borne diseases such as HIV and hepatitis B.

No it is not possible to get HIV from mosquitoes. When taking blood from someone mosquitoes do not inject blood from any previous person. The only thing that a mosquito injects is saliva, which acts as a lubricant and enables it to feed more efficiently. Secondly, HIV lives for only a short period inside the mosquito and does not reproduce.

There are no chances of getting HIV infection to the household members because of just staying with or taking care of HIV infected person in the house. Remember, the support from family members is very essential in HIV infected person's life. Following things should be followed while taking care of HIV infected person at home:

• Gloves should be worn during contact with blood or other body fluids that could possibly contain visible blood, such as urine, faeces, or vomit.
• Cuts, sores, or breaks on exposed skin should be covered with bandages.
• Hands and other parts of the body should be washed immediately after contact with blood or other body fluids.
• Surfaces soiled with blood should be disinfected appropriately.
• Practices such as sharing of razors and toothbrushes, that increase the likelihood of blood contact should be avoided.
• In case of infected women proper disposal of the menstrual pads should be done either by burning or burying them.

There are many reports of bite from HIV infected person but they say that bites do not result in HIV infection.
