@Prizlime yes it’s ramping up again sadly. The vaccine has meant that the likelihood of serious illness or death is reduced by something like 86% I think which is great and is true even if you’ve had only a couple of doses of the vaccine many months ago (but we’ll have to wait and see how long this lasts- could eventually wain quite a bit).
However Immunity to -catching Covid at all, to getting asymptomatic covid, or milder/moderate (ie you’re sick but don’t need to go to hospital) symptoms only seems to last at most 3-4 months after your last vaccine or infection. It could be as small a window as 40 days (in this respect as a corona virus it’s much more like cold than flu).
The really annoying news is this, reinfection increases the risk of long Covid and worse symptoms, instead of protecting you long term. In some large multi country studies they found something like 30% of people have at least one long Covid symptom 12 months or longer after infection (eg fatigue, lack of taste or smell, muscle pains, cognitive symptoms, hair loss). This was found to be the case among a large proportion of children also, I think maybe around 8-15% children get long Covid for at least 3 months after, it’s not very clear but it’s enough to be worried about reinfection among children I think. Fewer than 1 in 100,000 children may also develop MIS-C, which is a very dangerous but luckily very rare post Covid complication for children. However, if we are just “letting it rip” we could potentially see a troubling number of MIS-C and a huge amount of long Covid.
Other risk factors which increase the chance of getting long covid: being a woman, high BMI, smoker, co-morbidities (the more of them the higher the risk) having less money.
All this is just to say, yes very few people/organisations are doing anything to mitigate against it anymore. But it’s still worth thinking about the risks of reinfection- it doesn’t appear that getting a mild dose lots of times makes you super immune for example, it looks like it mainly increases the risk of long term complications. It’s annoying, because we’re all bored of it but that doesn’t mean the pandemic is over yet.
