Had a scare with my oldest. Complained of a headache then turned fever. At home test was neg but kept having fever and don’t want to eat. Took him in for a pcr and neg thank god. But it was HFM. I’m disgustingly relieved. Kid didn’t have any sores anywhere except a small one on his tonsil.
Doc said the at home tests are kinda useless for whatever strain is out now
Not sure how true but they’ve been getting a lot of false negatives because perhaps people are testing too early with at home tests. PCR picks it up immediately.
First off, I'm sorry to hear your oldest is ill and wish your child a speedy recovery. I've only heard horror stories about HFM, so I pray it's not as bad as it could be. Is there any effective treatment or just have to wait it out?
I completely disagree with the doc about antigen tests being useless, and it has nothing to do with the current strain. By this point, we've all likely been exposed to the virus in one way or another. Some have been infected, others vaccinated, many have had both. There used to be a longer time between exposure and symptoms because your immune system didn't recognize what was happening while the virus was replicating, though you may have been presymptomatic for 7-14 days. The initial symptoms are your immune system's way of getting you to be uncomfortable and rest in order for it to do it's work, but since the immune system didn't recognize the virus it didn't react right away. By the time you felt symptoms (many times even sooner), there was enough virus in your nasopharynx to detect using rapid antigen tests. Now, due to prior exposure, your immune system recognizes that toxic spike right away and you feel symptoms very soon after infection. In many cases, if you test right away there is not enough virus in your nasopharynx for RAT to detect. In this case, you are also likely not very contagious until RAT turns positive, indicating higher viral load. In some physicians' eyes, the fact that the patient has symptoms but the home test is negative indicates that they are useless, but I would argue they are still a very useful tool when you understand and use them properly.
