All this means is that India and Hong Kong use different cycle counts in their PCR tests.
Many of us have SarsCOV-2 virus in and on us. Most people’s innate immune system can hamper or destroy the virus before it affects them too badly.
People with weak or weakened innate immune systems start to experience some of the terrible effects that we hear about in the news. They have to rely on their adaptive immune system to produce anti-bodies and rid themselves of the virus.
If the cycle count on the PCR test is too high, it will pick up shed proteins even in very miniscule amounts. This is why so many people test positive but have no symptoms. Their natural immune system did what it was supposed to do and stopped the threat.
The creator of the PCR test said that it should never be used on people with no symptoms and should only be used at 25-30 cycle counts.
Each and every one of us walks around with MRSA on our skin. How ridiculous would it be to take swabs of everyone’s (including people with no symptoms) skin to diagnose who had a MRSA infection and who didn’t?
I used to do TB checks on arrivals at a time when a pre-boarding chest X ray was required to immigrate to the US.
Quite a few of the people from India with “normal” chest Xrays had active TB on arrival.
I would not believe any COVID test required to board a flight from India or Pakistan to the West. The airports should be closed.
