Q

SARS CoV 2 ORIGINS?

A
  • FIRST KNOWN INFECTIONS IN WUHAN, CHINA
  • THE ORIGINAL SOURCE OF VIRAL TRANSMISSION TO HUMANS UNCLEAR

  • MARCH 2021 WHO REPORT: HUMAN SPILLOVER VIA AN INTERMEDIATE ANIMAL HOST IS THE MOST LIKELY EXPLANATION, AND DIRECT SPILLOVER FROM BATS NEXT MOST LIKELY
  • ALTERNATIVE THEORY: SARS CoV 2 EMERGED IN A LABORATORY ACCIDENT FROM THE WUHAN INSTITUTE OF VIROLOGY, WHERE RESEARCH ON SARS CoV WAS UNDERWAY (NO DIRECT EVIDENCE FOR THIS)

Q

SOUTH KOREA VS NEW ZELAND VS INDIA - COVID RESPONSE

A

SOUTH KOREA:

  • PANDEMIC RESPONSE CONSIDERED EXCEPTIONAL
  • ADVANCED USE OF DIGITAL TECHNOLOGY AND SOCIAL INTERVENTIONS SUCH AS HIGHLY EFFECTIVE TEST-TRACE-ISOLATE SYSTEM + QUARANTINE MEASURES FOR TRAVELLERS ARIVING IN THE COUNTRY

NEW ZELAND:

  • ALSO EFFECTIVE APPROACH
  • EARLY PUBLIC POLICIES, EARLY AND AGRESSIVE TRAVEL RESTRICTIONS AND BORDER CLOSURES

INDIA:

  • VERY STRICT LOCKDOWN IN THE FIRST WAVE, LEADING TO LOW NUMBER OF CASES
  • SUCH MEASURES NOT REPEATED IN THE 2ND WAVE (APRIL 2021), LEADING TO 400 000+ NEW DAILY CASES
  • CULMINATION OF MORE TRANSMISSIBLE VARIANTS (DELTA)
  • LACK OF HOSPITAL STRUCTURE FOR TREATING COVID PATIENTS
  • CLINICAL EQUIPMENT ACQUIRED LATE, GOVERNMENT NOT MANDATING BEHAVIOURAL STRATEGIES, OCCURENCE OF SUPER-SPREADER SOCIAL GATHERINGS —> PRSENTED IDEAL CONDITIONS FOR HIGH-MORTALITY CHAIN OF TRANSMISSION
