Best Infectious Diseases Service in India

OVERVIEWInfectious diseases are caused by microorganisms like parasites, viruses, bacteria, or fungi that multiply in the body and cause tissue damage. While some microorganisms are harmless, others can cause disease.

Many infectious diseases are contagious and spread through person-to-person contact, animal or insect bites, contaminated food or water, or exposure to environmental organisms.

Indirect contact can also cause the transmission of several disease-causing pathogens. For instance, pathogens present on inanimate items, such as table surfaces, doorknobs, and even faucet handles can cause infectious diseases.

Antibiotics are administered for the treatment of bacterial infections.


Antivirals are recommended for the management of viral infections.


Antifungals are administered to treat fungal infections. Fungal infections are treated both with topical and oral medications.
