Most fevers are caused by viral infections and settle in a few days, but dengue, typhoid, malaria, urinary and chest infections need specific tests and treatment. Dr Sujith Chadala at Continental Hospitals, Gachibowli examines you, orders targeted tests such as a blood count, dengue NS1 or blood culture, and decides whether you can be treated at home or need admission.

Overview
In Hyderabad, fever cases rise sharply during and after the monsoon, when dengue, malaria and typhoid are common alongside seasonal viral fevers. The first few days of illness often look similar, which is why examination and a few well-timed tests matter.
Antibiotics do not help viral fever and can cause side effects and resistance. They are used when a bacterial infection is likely or proven — for example typhoid, urinary infection or pneumonia.
Dengue needs close watching of the platelet count, hydration and warning signs, particularly around days three to seven when the fever starts to come down. Older adults and people with diabetes, kidney or heart disease may need admission earlier.
What this covers
- Viral fever and seasonal flu
- Dengue fever and low platelets
- Typhoid (enteric fever)
- Malaria
- Urinary tract infections
- Pneumonia and chest infections
- Stomach infections with vomiting or loose motions
- Fever lasting more than a week (prolonged fever)
When should you see a doctor?
- Fever above 101°F (38.3°C) lasting more than two to three days
- Fever with severe body pain, rash, or pain behind the eyes
- Burning urine, back pain with fever, or shivering
- Cough with fever and breathlessness
- Any fever in someone with diabetes, kidney disease, cancer treatment or advanced age
How care works
- 1
Examine and time the tests
The day of fever matters: dengue NS1 is most useful early, antibodies later; blood cultures before antibiotics.
- 2
Treat the cause
Fluids and fever control for viral illness; specific treatment for typhoid, malaria or bacterial infections.
- 3
Watch for warning signs
You will be told exactly which symptoms mean you should come back or go to the emergency department.
- 4
Admit when safer
If fluids, platelets, oxygen or blood pressure need closer monitoring, admission is arranged at Continental Hospitals.
Emergency warning signs
Call 108 or go to the nearest emergency department immediately if you notice:
- Severe abdominal pain, persistent vomiting or bleeding from gums or nose during dengue
- Very little urine, cold hands and feet, or feeling faint
- Breathlessness, chest pain or confusion with fever
- Fever with a stiff neck, severe headache or a spreading purple rash
Before your visit
- A note of the day the fever started and the highest temperature
- All medicines taken so far, including any antibiotics or painkillers
- Any blood test reports already done
- Avoid ibuprofen and aspirin if dengue is possible — paracetamol is safer until a doctor advises
Frequently asked questions
When should I get tested for dengue?
The dengue NS1 antigen test is most useful in the first five days of fever. After about day five, dengue IgM antibodies are more helpful. A complete blood count tracks platelets and haematocrit.
At what platelet count is admission needed in dengue?
There is no single number. Admission depends on warning signs, hydration, bleeding, blood pressure and other illnesses as much as the platelet count. Many people with low platelets recover safely at home with close monitoring.
Should I take antibiotics for viral fever?
No. Antibiotics do not act on viruses. They are prescribed only when a bacterial infection such as typhoid, urinary infection or pneumonia is suspected or confirmed.
Which painkiller is safe during fever?
Paracetamol is generally safe at the recommended dose. Avoid ibuprofen, diclofenac and aspirin unless dengue has been ruled out, because they can increase bleeding risk.
