Have been getting low fever for past 5 days, is this malaria?

Are you exposed? There are virtually no native malaria cases in the USA. You would have had to have been in an area where the mosquitoes are carriers. In and by itself low grade fevers are not typical of malaria and there are dozens of other more likely explanations.
Fever+travel=malaria. To be safe, one should always assume that fever after travel to an area with malaria risk is indeed malaria and get it checked out. People die every year from malaria in part because the diagnosis is not considered. Of course other diagnoses are much more likely (cold, uti, etc) but much less dangerous. See a travel medicine expert for consultation.
