Aimee, here is an answer to your question:
CNN: Does that mean people can proceed with spring break and other travel plans, or do they need to postpone them?
Dr. Wen: I don't think travel plans need to be put on hold. To be sure, there is uncertainty, as some places might have low rates of Covid-19 now but may have increased rates when you travel. However, that may be the case for the foreseeable future. Very few activities that we do have no risk. Traveling certainly entails risk, but you can reduce that risk by making sure you are vaccinated and boosted. Wearing a mask in crowded indoor settings further reduces risk. In the United States, follow the CDC guidance and make sure to wear a mask in areas that have high Covid-19 community levels. If you are planning international travel, know the rules, including whether you have to have proof of vaccination or a recent negative test.
CNN: Could BA.2 cause another surge in the US, and if so, should restrictions come back now?
Wen: BA.2 could certainly lead to another uptick in Covid-19 infections in the US. There are already some signs that the sharp decline in new cases is leveling out, and if the US follows Europe, as it has before, a rise in cases could be weeks away.
That said, I don't think it means we need to reinstate restrictions. The goal of vaccination is to decouple infections from hospitalizations and severe illness. If there is a surge in infections but hospitalizations don't rise to the point that our health care system becomes overwhelmed, then I think government-imposed mandates are not warranted. Here, the new CDC guidelines are very helpful, as they take into account severe illness -- severe enough to cause hospitalizations -- as the metric for masking, not just any infection.
Of course, just because the government isn't requiring masks doesn't mean that individuals shouldn't mask or take other precautions. At this point in the pandemic, people should make decisions based on their own medical circumstances and tolerance of risk.
