Dear Suneetha,
The symptoms as mentioned in your post can be attributed to either
Viral exanthem or
Rickettsial fever.
Symptomatic management involves:
1. Analgesic anti-pyretic agents like Paracetamol.
2. Anti biotics like Doxycycline preparations (to be taken only under the guidance of your Physician).
3.
Anti histamines & anti-tussive preparations for cold & cough.
4. Application of Calamine lotion for symptomatic relief of rashes.
5. Maintain adequate hydration & proper nutrition status.
If there is no relief even after 02 days, he needs to get certain investigations like
complete blood count, urine examination, peripheral smear for malaria, Dengue check,
blood culture & Weil felix test.
These investigations will be helpful in detecting the pathological cause & formulating further plan of management.
Wishing him a good health.
Take care.
