Welcome to Healthcare Magic!
Your husband seems to be having a viral syndrome
Most likely a mononucleosis/mono., rarely same symptoms are possible with HIV seroconversion
or a hematologic malignancy.
It is a real pitiable situation of healthcare at your place that you have to wait for so long.
You can start him on OTC Ultracet
tablet 6hourly topped up by Paracetamol(acetaminophen
)500 mg as required.
You can mean while get the mono and HIV serology done and a CBC LFT done just to rule out prime suspects.
I hope the advise would be useful for you.
