It’s important to have this all down guys but
Antibodies don’t “wear off”. Neutralizing antibodies may wane but you’ve got memory B cells to ramp back up production. I really wouldn’t be overly concerned with it. Then you’ve got cd8 and cd4 T cells and all that jazz that I knew at one time but am way to lazy to look up again. |

Measuring T cells is a real bitch iirc. It can be done but honestly I have no recollection of how

Alex Berenson @AlexBerenson Florida again: People over 85 (not 75, 85) make up 1 in 3 of #COVID deaths statewide - 5x as many deaths as everyone under 55. Put another way: if you are over 85, you have a 1 in 300 chance of dying of #COVID in Florida in the last five months. Under 55? 1 in 33,000. |

My understanding is that the serology labs can produce some false positives, but negatives are reliable.

Yes serology labs can produce false positives and very rarely produce a false negative and PCR testing can produce false negatives and very rarely produce false positives.

ADH requires a person exposed to COVID-19 to complete a 14-day quarantine period, even though they may have a negative test result during the quarantine period.Quarantine of persons known to be exposed to someone with COVID-19 is a key strategy to stopping the spread of the illness. https://www.cdc.gov/coronavirus/2019...uarantine.html Quarantine is used to keep someone who might have been exposed to COVID-19 away from others. Quarantine helps prevent spread of disease that can occur before a person knows they are sick or if they are infected with the virus without feeling symptoms. People in quarantine should stay home, separate themselves from others, monitor their health, and follow directions from their state or local health department. |

Seems the nuance is in the definition of exposure which by cdc guidelines in <6' for >15 minutes.
https://www.cdc.gov/coronavirus/2019...endations.html ** Data to inform the definition of close contact are limited. Factors to consider when defining close contact include proximity, the duration of exposure (e.g., longer exposure time likely increases exposure risk), and whether the exposure was to a person with symptoms (e.g., coughing likely increases exposure risk). While research indicates cloth face coverings may help those who are infected from spreading the infection, there is less information regarding whether cloth face coverings offer any protection for a contact exposed to a symptomatic or asymptomatic patient. Therefore, the determination of close contact should be made irrespective of whether the person with COVID-19 or the contact was wearing a cloth face covering. Because the general public has not received training on proper selection and use of respiratory PPE, it cannot be certain whether respiratory PPE worn during contact with an individual with COVID-19 infection protected them from exposure. Therefore, as a conservative approach, the determination of close contact should generally be made irrespective of whether the contact was wearing respiratory PPE, which is recommended for health care personnel and other trained users, or a cloth face covering recommended for the general public. ***Data are insufficient to precisely define the duration of time that constitutes a prolonged exposure. Recommendations vary on the length of time of exposure, but 15 minutes of close exposure can be used as an operational definition. Brief interactions are less likely to result in transmission; however, symptoms and the type of interaction (e.g., did the infected person cough directly into the face of the exposed individual) remain important. |

What about the fact that this very piece of information states that their dats is insufficient? What about since they did this "update" and changed those criteria cases have ballooned? |

Since there are such greater odds to die in car crashes why are there more total deaths with covid? |
