Infection Specialists in Delhi

How can I tell if an infection is bacterial or viral?

Laboratory testing such as blood cultures, complete blood counts, and specific antigen or PCR tests is usually needed to distinguish them, since symptoms like fever and fatigue can overlap; a doctor can order the right test based on the suspected site.

Do all infections need antibiotics?

No, antibiotics only work against bacterial infections; viral infections such as most colds and flu are treated with supportive care or antivirals, and unnecessary antibiotic use contributes to resistance.

When does an infection become an emergency?

Warning signs include a rapid heart rate, confusion, very high or very low body temperature, or spreading redness and swelling, which can indicate the infection is becoming systemic and needs urgent medical attention.

How long does it take to recover from a typical infection?

Recovery time varies widely by organism and site, from a few days for a mild localized infection to several weeks for more serious systemic infections requiring intravenous treatment.

Can infections be prevented?

Yes, frequent handwashing, staying current on vaccinations, safe food and water handling, and prompt wound care substantially lower the risk of most common infections.

Is it safe to stop antibiotics once I feel better?

No, stopping early can allow surviving bacteria to multiply again and can promote antibiotic resistance; the full prescribed course should be completed unless a doctor advises otherwise.
