DIFFERENT STRAIN OF COVID 19

LOOKING AT SINGAPORE, INDONESIA AND PHILIPPINES ON COVID 19 CASES, SINGAPORE HAS LESS FATALITIES THAN INDONESIA AND PHILIPPINES.
3 COUNTRIES ARE IN HOT TEMPERATURE ZONE BUT WHY THE DIFFERENCES.
1 REASON IS INDONESIA AND PHILIPPINES HAVE EUROPEAN STRAIN OF COVID 19.
SINGAPORE HAS ASIAN STRAIN OF COVID 19.
COMMON AREA IS INCREASE IN CASES AFTER LOCKDOWN.
LOCKDOWN IS MAKING THE POOR TO SUFFER LIKE THE CASES OF FOREIGN WORKERS REACHING 30,000.
SO THE SLUMPS IN INDONESIA AND PHILIPPINES HAVE THE MOST CASES AND DEATH.
OVERCROWDED HOUSES CONTRIBUTE TO THE INCREASE.
