Types of Infectious Diseases - CSV
Infectious diseases are illnesses caused by pathogens (viruses, bacteria, fungi, parasites, etc.) that invade and multiply in the human body. Under Japan's Infectious Diseases Control Law, they are classified into five categories (Category I to V) based on infectivity and severity, with different reporting systems and countermeasures established for each. Influenza, COVID-19, tuberculosis, malaria, and AIDS have become major global public health challenges, with international organizations such as the WHO and national governments working on prevention and management.
