  1. I am confused about something, can you please explain. If a rapid test as a sensitivity of 60% then that means it cannot be used to rule out as a test needs a sensitivity of 95% to be able to safely rule out. However since it has a specificity of 98% then it can be used to diagnose and rule in as a test needs a specificity of >95% to be able to confirm as the results then become pathognomonic. I'm confused as to how the rapid test can be used to rule out if it has a sensitivity of 60% because that will mean that it can only pick up 60% of a the time. 40% is a very large number of cases it misses so you cannot say that this patient for sure does not have this disease if it is known to miss the disease by 40% of the time. If sensitivity was 95% then you could say that it will always pick of the disease so if the result comes but negative it's for sure negative but probably no specific to the disease as other diseases may make the test positive too unless it both sensitive and specific like the PCR. Anyway can you explain it I'm not trying to be condescending I honestly don't understand.

  2. As i have finish the video i learn that flu and covid19 have 1 thing in common
    1. They have the same symptoms
    2. They have the same testing procedures
    3. They have the same number of cases and deaths annually

    The only difference of this two is flu is not a pandemic that requires lockdown hence covidq9 requires,,wtf

  3. But if you experience the flu symptoms nowadays you will be now suspected without testing having infected with corona virus,and you will be subjected to quarantine for 14 days ,if found positive you will be locked up without medication if you dont have money to pay for the hospital bills,,then if you die you will be cremated and put in a jar,,you died bcoz of covid19 not with influenza

  4. Does a flu or cold virus also cause ulcers in one's mouth?
    What should one do to get rid of mouth ulcers?
    I wonder if CoViD 19 patients suffer from mouth ulcers.
