Wait, what? I'm lost.

Child A: negative rapid, negative PCR
Child B: positive rapid, no PCR

Yet you are "now wondering the the at home test was a false negative for the one who tested positive"? Your last sentence contradicts your first two.

Whatever, you should keep testing the one who tested negative on the rapid test. If one kid tested positive, the other may just not be far enough along in the infection process for it to show up. Not necessarily a "false negative," just not detectable yet.

For all those with partially negative partially positive families - it is more common than you think. In the beginning of the pandemic, before vaccines, we had one positive child and one positive parent. The other parent and child were definitely exposed but never got sick. In retrospect, it is clear that the infected child and parent had the closest contact at a critical time. (Pre-symptomatic unmasked car ride together in the 12 hours before 1st symptoms.).

Infected parent slept in same bed with non-infected partner (divorced family) prior to becoming symptomatic and testing positive. Partner never was infected.

What our experience showed me was that household transmission is not a given. I think a lot depends on viral dose exposure (so masking, distance and ventilation helped) and degree of close exposure when someone around you is shedding highly.

We had a second exposure post-vaccination. The infected (and fully vaccinated but pre-boosted stage) person had close contact with a family member who was asymptomatic but infected.

Rapid false negatives are possible because you can be infected with the virus which has not replicated yet to sufficient levels to trigger the rapid positive, but rapid false positives are extremely unlikely, especially in a high prevalence environment.

One child tested negative and one child tested positive. Took the one who tested negative to the pediatrician for PCR test and it was negative. I am now wondering the the at home test was a false negative for the one who tested positive.

I assume they weren´t sick, just infected.

Well, yes, that’s my point. Rapid tests in school appear to be catching people who were infected but were unaware they were infected, presumably because they either had no symptoms or they had mild non-specific symptoms they didn’t attribute to COVID. Nonetheless those 40 people who tested rapid positive were presumably capable of transmitting to others, so the rapid test handout presumably prevented some forward transmission.

I wish rapid tests were freely available at MCPS schools for all staff, teachers, students and families thereof. I wish that schools offered regular pooled PCR salivia testing.l

At this level of transmission, pooled testing would be pretty pointless, because every pooled sample would show Covid! It was also hard to do last year because of low numbers of opt-ins and the lack of isolated class groupings in many schools.

The schools have been doing pooled PCR the whole time. Both my kids are opted in. They have gotten tested almost weekly, or at least 3x a month. We are in Upper County.
You can get rapid tests at the library right now. If you work from home, pick one of the ones open 11-2. Lines are nonexistent. Get there early, their supply is out in an hour.

Two negative (HS and MS)

Take it up with the CDC, it's national policy. The country would grind to a halt if this was required, but I guess that's what you want.

FWIW, Monday my school reported 12 cases and gave out rapid tests. Tuesday my school reported 40 cases. So that’s a lot of people caught by the rapid tests who maybe didn’t know they were sick and are presumably now out of school?

I’ve had one kid test positive over a week ago. The rest of us didn’t get it at all despite never being apart from him. He has no symptoms.

Vaccines for the win!

Nah, that is just luck. Covid is spreading in plenty of vaccinated families.

Pretty sure it’s because we were vaccinated, given that we were all together in close proximity to him and didn’t catch it. That’s not luck. If we weren’t vaccinated we’d have got it.

A big part of the teaching staff at our school has it. It's spreading like wildfire in schools that are overcrowded and where children can't seem to follow mask protocols. You really were very lucky.

We are also all vaccinated. We all got it anyway, even those of us who are boostered.

Back to the topic at hand, 2/2 negative, we all had COVID 2 weeks ago.

My ES kid was negative. We did travel (by car) over the break but seem to have dodged it so far. Kid has worn KN95 all year and hasn't even caught a cold yet this school year. Kind of amazed.
