No, HIV does not spread through the respiratory tract. As long as it doesn't cut the skin, you don't have to worry if the virus doesn't touch the blood.

Even if you have HIV, your nasal mucosa is epithelial cells, and HIV can only be parasitic in lymphocytes, which only exist in blood and lymphoid organs. So as long as there is no blood, respiratory mucosa and digestive tract mucosa are defensive.

Moreover, it is impossible for HIV to remain active on the skin of your hands for a long time, and it will be inactivated in a short time.
