Best Questions:

If the line on my at-home Covid test seems to be getting lighter, does that mean I’m getting better?  

If you see a second line on your at-home COVID test, you’re infectious and should consider yourself capable of spreading the virus. But it’s actually true that the darkness and speed at which the line shows up is generally an indicator of how much of an antigen response your body has to the virus. A dark line that shows up just a few minutes after you take the test means you’ve got a lot of antigens in there and therefore, probably a higher viral load. A very faint line means you’ve got fewer antigens and could mean your infection is just beginning or starting to wane. It’s certainly not an exact science, but if you see a heavy line for a few days and then it starts to get fainter on every subsequent test you take, you can assume that your body is doing its thing and you’re on the mend, though you’re still infectious until there’s no line at all.

If I have cold symptoms should I still be COVID testing?

Yes, it’s still worth it to test for COVID if you’re feeling sick. While we know that isolating for 5 days is a nuisance for some and a financial hardship for others, the reality is that everyone will be in close contact with someone who has a newborn baby or an elderly person at home who needs to be protected. COVID is still much deadlier than the flu - one study found over one in four patients hospitalized with COVID died, compared to less than one in ten with the flu. If you test negative, you still might have COVID (or the flu or something else contagious), so it’s best to test a few days in a row if you have symptoms and to stay home if you’re sick even if you test negative. The virus is still here, and we do have some control of whether we spread it to our friends, coworkers, and families. Stay safe out there!

What can we do to better prepare for mosquito- and tick-borne viruses in the US?

Our best read below touches on just how unprepared the US is for the onslaught of mosquito and tick-borne diseases that are already spreading here and are bound to get worse with climate change. This year, we’ve seen locally acquired malaria cases for the first time in decades. Dengue already spreads here regularly, and Zika, chikungunya, and even tropical parasites are already problems. Employers should be practicing good mosquito control - everything from eliminating standing water to adding screens on windows and doors. They should also protect employees who work outdoors from insect bites, whether with physical barriers like screened-in booths, insect repellant, or with appropriate uniforms. Meanwhile, we hope the US will invest in tracking and alert systems, vaccines for insect-borne viruses, and infrastructure that’s more mosquito- and tick-proof.
