Several factors contribute to the scarcity of effective treatments for certain diseases. These include:
Drug Resistance: Overuse and misuse of antibiotics and antiviral medications can lead to the development of drug-resistant strains of pathogens. Emerging Infectious Diseases: New or re-emerging diseases may lack existing treatments due to the novelty or rarity of the pathogen. Economic Barriers: High costs of research and development can limit pharmaceutical companies' interest in developing treatments for diseases that are not profitable. Regulatory Hurdles: Stringent regulatory requirements can slow down the approval process for new treatments.
