A decade after SARS: strategies for controlling emerging coronaviruses

Area of Science:

• Virology
• Infectious Diseases
• Public Health

Background:

• Emergence of novel human coronaviruses, SARS-CoV and MERS-CoV, in the 21st century.
• Both viruses cause severe acute respiratory distress syndrome (ARDS) with high mortality rates.
• Lack of approved vaccines or antiviral drugs necessitates urgent research.

Purpose of the Study:

• To review the emergence and identification of novel human coronaviruses in the last decade.
• To discuss key biological features, including tropism and receptor usage.
• To summarize current approaches for developing broadly effective vaccines against emerging coronaviruses.

Main Methods:

• Literature review of scientific publications on human coronaviruses.
• Analysis of viral emergence, identification, and epidemiological data.
• Synthesis of information on viral pathogenesis and vaccine development strategies.

Main Results:

• Detailed overview of SARS-CoV and MERS-CoV emergence and characteristics.
• Discussion of viral tropism and specific host cell receptor interactions.
• Summary of diverse vaccine development platforms and their potential.

Conclusions:

• Urgent need for effective vaccines and therapeutics against emerging coronaviruses.
• Understanding viral biology is crucial for developing broad-spectrum countermeasures.
• Continued research into novel vaccine strategies is a global health priority.
