Sewer sampling, the authors say, could be expanded to track other infectious diseases such as H5N1 avian flu or mpox or to detect unexpected pathogens.
Plaque growth can lead to a higher risk of heart attack, stroke, and other life-threatening cardiovascular events for as long as 1 year.
Post-exertional malaise, or exercise intolerance, was seen in 36% of those with long COVID.

The experimental cancer drug sabizabulin slashed all-cause deaths by 55.2% over placebo in high-risk hospitalized COVID-19 patients by 60 days and was tied to fewer adverse events, according to interim results of a randomized, controlled phase 3 trial published yesterday in NEJM Evidence.
BA.4 and BA.5—which now cause more than 70% of US cases—are 4 times more resistant to 3 vaccine doses than BA.2 is, and only 1 of 19 monoclonal antibodies tested showed efficacy against those subvariants.
In global developments, cases rose for the fourth straight week, led by the BA.4 and BA.5 Omicron subvariants.
Pre-Omicron, the leading causes of death were heart disease (20.1%), cancer (17.5%), and COVID-19 (12.2%).
A study in Ontario suggests that, compared with a third dose of mRNA COVID vaccine, a fourth dose improved protection against infection and severe outcomes among long-term care residents during the Omicron wave. The study was published today in The BMJ.
BA.5 now makes up 53.6% of cases, BA.4 makes up 16.5%, and both are highly transmissible.
The odds of having long COVID fell from 48% before vaccines to 16% after a third vaccine dose.
A new study shows that the proportion of children diagnosed as having COVID-19 and croup was significantly higher during the Omicron surge than in earlier waves dominated by other variants.
Croup is an upper airway infection generally affecting children. It causes swelling around the larynx, trachea, and bronchi, resulting in labored breathing and a "barking" cough.
Though all benefited, those at lowest and highest body weights were at greater risk, possibly due to differences in immune response.
The mobile units are geared toward reaching high-risk communities and come as the US and other countries battle rising COVID activity.
