What could be causing my mother?s persistent high fever of up to 104?F, severe headache, chills, and dropping platelet count, given that her tests for dengue, malaria, COVID-19, and typhoid are all negative, and her symptoms continue despite taking Meftal Forte, Dolo, and Ceftas?
Since tests for common infections are negative and her fever persists despite taking paracetamol (Dolo), mefenamic acid (Meftal Forte), and cefixime (Ceftas), other conditions need consideration. This could be a rickettsial infection (like scrub typhus), another viral illness, or an atypical infection. Because her platelet count is dropping, please consult her doctor or visit an emergency room immediately for further evaluation, blood monitoring, and potentially adjusting her treatment.
