It’s still undetermined, but more studies are showing that a vaccine can reduce your chances of longer-term symptoms. Just how much a vaccine can reduce your risk of long COVID is still unclear, and all of them showed that long COVID can still be possible in vaccinated people. Either way, unvaccinated people get more severe COVID and are more likely to be hospitalized, which increases their likelihood of having lasting health issues. For those who are vaccinated, the best way to avoid long COVID is to avoid getting COVID altogether - stay up to date on your booster, avoid being indoors with people who are sick, and consider wearing a mask in high-risk situations.
Unfortunately, yes. Recently a healthcare worker broke the (known) record by having two unique COVID cases within 20 days. Even if you recently had COVID during the last surge, it’s possible that you can get it again now, in part because there are different variants floating around (like BA.2 and an even new version of it). If you have new symptoms, don’t dismiss them just because you had COVID a few months back - it’s still worth getting tested and staying home when you’re sick!
It’s still very early, but the leading contender in terms of what’s causing this hepatitis outbreak in kids is actually an adenovirus, which is most commonly associated with common colds. Nearly 75% of patients that were seen with hepatitis in the UK tested positive for that kind of virus. They’re still investigating if it has something to do with weakened immune systems after nearly 2 years of not catching any colds, or if it’s possibly related to previous COVID infection. Right now, it does seem related to catching colds, but it’s not likely foodborne. The same precautions that you can take to prevent spreading COVID will also prevent spreading the adenovirus that is linked to this hepatitis outbreak. We’ll continue to keep a close eye on this as investigators learn more about what’s causing it. In the meantime, parents can watch for fever, severe abdominal pain, dark urine, light-colored stools, and - most telling - yellow coloring in the eyes or skin. Seek medical treatment immediately if a child has severe symptoms.
Unfortunately, no. Someone who has been infected with norovirus sheds the virus at very high levels for 24 hours before their symptoms begin (and at high levels for up to 48 hours after their symptoms stop). It’s incredibly infectious in the home setting where people are sharing space and bathrooms, and touching the same surfaces. Just a few norovirus particles are enough to get someone else sick. The best practice is clearly to exclude someone who has been exposed to noro in their home or intimate relationships for at least 3 days. If they develop symptoms, they should stay out until they’ve been symptom free for at least 48 hours.
