Headaches are the usual symptoms to have when you have hantavirus. You can take Tylenol to help with your headache. Since you believe you have the flu you may not seek treatment right away because you don’t know that you have hantavirus. When you have the flu and you take medicine for it, your headache begins to go away, but with hantavirus, it won’t.
The infectious disease is infected with your body so much that any over-the-counter medicine is not going to work. It might even make your headaches worse because the disease is much stronger. After a few days, you should go into the hospital where they will place into intensive care. In intensive care, you will be made to feel comfortable. You may even need to be a respirator to help with your breathing. The infectious disease will go away in a few weeks or days if it’s caught early enough.
