New York, November 29 : The world needs to improve healthcare capabilities to respond to established infectious diseases like malaria and tuberculosis while also responding to emerging threats, the outgoing director of National Institute of Allergy and Infectious Diseases (NIAID), Dr Anthony S. Fauci, has stressed.

Once considered a potentially static field of medicine, the discipline of studying infectious diseases has proven to be dynamic as emerging and reemerging infectious diseases present continuous challenges, Fauci wrote in a perspective in 'The New England Journal of Medicine'. Indian-Origin Scientist Discovers New Omicron Subvariant Resistant to All Known Antibody Therapies.

Dr Fauci will step down from his positions as NIAID director, chief of NIAID's Laboratory of Immunoregulation and chief medical advisor to President Joe Biden in December. Although Covid-19 was "the loudest wake-up call in more than a century to our vulnerability to outbreaks of emerging infectious diseases," Dr Fauci wrote.

One success of the response was the rapid development, testing and distribution of Covid-19 vaccines, thanks to years of research and investment in new and highly adaptable vaccine platforms and structural biology tools to design vaccine immunogens. Infections Remain Leading Cause of Death Globally and in India, Five Bacteria Responsible for at Least 6.8 Lakh Deaths in 2019: Report.

These technological advances, among others, will greatly benefit the field of infectious diseases, he wrote. In the perspective, Dr Fauci said that the emergence of HIV/AIDS in 1981 led to a sharp increase in interest in infectious diseases among people entering the field of medicine.

Since then, infectious disease specialists have faced numerous medical challenges, including the 2009 H1N1 influenza pandemic, Ebola, Zika, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and Covid-19, he said.
