Asthma but i forgot to ask about hanta virus. can asthma be one of the early signs of hanta virus?

No : Hantavirus infection is contracted from exposure of infected rodents. Four to 10 days after the initial phase of illness, the late symptoms of hantavirus pulmonary syndrome (hps) appear. These are cough and shortness of breath, with the sensation of a tight band around the chest and a pillow over the face. The lungs fill with fluid. In asthma lungs have more mucus, but do not fill with fluid.

Respiratory sx's : Respiratory sx's come later. Initial symptoms of hantavirus pulmonary syndrome can include: fever, chills, nausea, vomiting, abdominal pain, diarrhea, headaches and muscular pain. 3 to 7 days later there may be trouble breathing, low blood pressure & productive cough.
