BAYES' THEOREM: The basic reason we get so many false positives to COVID19. The disease is so rare that the number of false positives greatly outnumbers the people who truly have the disease: THE MATHS:

"The national statistician has downgraded its estimate of coronavirus in England on October 17 to just 4.89 people per 10,000." or ~ 0.05%. That means that only 1 in 2000 people may be carrying SARS related viral RNA fragments which could be 2 months old. https://t.co/XqpNaY6BzQ

Try it yourself to understand how many false positives you get by changing minor variables: \U0001f447https://t.co/7wVMvrpgAW pic.twitter.com/PHbweWK1TK

LATERAL FLOW: False positive rate of "0.4% with a sensitivity of 58% and specificity of 99.6%, would mean that 100\u2009000 people being tested would find 630 positives\u2014of which only 230 would actually have covid-19, while 400 would be false positives.

2. Apparently @MattHancock tells HoC 17/09 how ONS \u201cadjusts for False Positives\u201d. Looked it up.@DesmondSwayne asks;@MattHancock doesn\u2019t answer.
Obfuscates with \u201crigorous Bayesian mathematics\u201d

#BAYESTHEOREM @ Cambridge University. 0.4% of 262 students came back as positive after the first "test". All came back as negative after the second. Government only tests once. ONS would say there is 0.4% prevalence instead it's 0%. pic.twitter.com/zeAQAAOeRN

"I am very happy for one of my academics to take him through the rigorous Bayesian mathematics, which I am sure will help to elucidate the debate on this matter still further." @MattHancock to @DesmondSwaynehttps://t.co/pZcFlMBKEZ

Numerical details aside, the use of Bayes's theorem and the principle described are valid. Taught in epidemiology courses.

Extreme example. If disease prevalence is zero, predictive value of positive test is zero. Every positive is false positive.

This is what @Snowden had to say about @durov. Since then Telegram introduced the option of end to end encrypted chats not saved in Telegram servers. These private chats cannot be forwarded, and none of the participants can capture screenshots of

More from Category c19
The #Corona crisis began with a panopticon of absurd events, improbable coincidences and outright lies.
Time for a review of the impossibilities.
A thread 🧵
1/ At the end of December 2019, Wenliang, an eye doctor from Wuhan, noticed an allegedly unusual incidence of pneumonia. It remains a mystery what is unusual about 44 patients in a city with over 8 million citizens during winter.
2/ On Jan. 5, WHO informs for the first time about a pneumonia of unknown cause, which it can clarify by 7 January. The virus is believed to be a close relative of SARS. A fish market allegedly is the origin. The #Zoonosis legend, unproven until today, is born.
3/ On Jan. 10, the first gene sequence of the virus today called #SARS-CoV2 appears at https://t.co/tqxKgyykBr, and on Jan. 12, 4 more sequences are published by @edwardcholmes in the GISAID (Global Initiative on Sharing All Influenza Data)
4/ As early as January 13, just a single day later, WHO accepts Mr. #Drosten|s PCR testing protocol as gold

In ancient times, our grandparents used to follow typical natural way of caring the needs of a child. All they used were more of natural products than chemical based for the growth of child.
One of major step followed was to feed Gurbach Jadd/ Vasa Kommu/ Acorus Calamus for initiating good speech ability in a child. This stem was needed to babies on Tuesdays and Sundays in mother's milk.
Vasa is feed to baby after the 1st bath on 12th day in week. Weekly only thrice it is fed and named as :
Budhwar - Budhi Vasa
Mangalwar - Vaak Vasa
Ravi Vaar - Aayush Vasa
This stem is burnt and rubbed against the grinding stone in mother's milk or warm water to get a paste
The procedure to make it is in the link

It should not be given daily to the child. Other main benefits are
1. It clears the phlegm in child's throat caused due to continuous milk intake. It clears the tracts and breathing is effortless.
2. Digestion
For children who haven't got their speech and is delayed than usual should feed this vasa on these days in week atleast for 6months. Don't get carried away with this dialogue
