CAMBRIDGE, Mass. - As novel coronavirus cases climb, Cambridge-based tech startup Biobot is looking at an early clue lurking underground - sewage.

The company is analyzing the amount of COVID-19 in local wastewater, working with hundreds of communities across the country.

By testing wastewater, the company has found it's able to detect COVID levels in an area about a week before human testing catches up, since the virus is present in, shall we say, a person's excrement, before symptoms appear.

Biobot cofounder and President Newsha Ghaeli explained how one county uses its data to create a "heat map" of COVID clusters.

"What they can do," said Ghaeli, "is in real time they're routing their mobile testing vans to the communities that, that week, have the highest viral load in wastewater."

Biobot piloted this approach in early March with the Massachusetts Water Resources Authority, which covers an area that has accounted for about 45% of the state's COVID cases. According to MWRA's latest data, the eastern part of the Commonwealth is experiencing a spike not seen since April.

Biobot was looking at opioid levels in wastewater before its current work tracking COVID-19. For example, Ghaeli said one city figured out most of its opioid consumption was in the form of prescription painkillers, not heroin - information that helped create a strategy.

"They shifted their resources behind, like, medication drop-off units, educational material around the adverse effects of prescription opioids," said Ghaeli. "And they decreased overdoses by 40%."

Until this summer, Biobot was offering its COVID services free - but now, it's charging local governments, schools, universities and other groups. So far, the company has generated data representing about 10% of the country.

As summer kicks into full gear, North Carolina dentists stressed the importance of maintaining children's dental health.

Dr. Miranda Kalaskey, a dentist in Raleigh and member of the North Carolina Dental Society, said with more outdoor activities and changing routines, dental care can often be neglected, leading to cavities and dental trauma. Her advice is for parents to keep up with preventive care and encourage healthier eating habits.

"Try to pick a healthy summer snack. That can be fruit. That can be vegetables. Just not something dry, not something processed," Kalaskey outlined. "And the more processed you have, the more dried it is, the more likely it is to stick to their teeth."

She pointed out left-behind food can cause cavities. Tooth decay is the most common chronic disease among children in the U.S., with more than half of eight-year-olds having had at least one cavity in their baby teeth, according to the Centers for Disease Control and Prevention.

Warmer weather also means more outdoor play. Kalaskey highlighted the rise in dental trauma cases during the summer because of increased outdoor play and sports activities.

"Oftentimes, kids are going and playing basketball, and sometimes high schools are really good about, 'Hey, here's a mouth guard,' or 'You need to get a mouth guard for practice,'" Kalaskey noted. "But during the summer, a lot of times kids will play with other kids, which is great, but making sure they're aware that tooth trauma is a thing."

If a tooth gets knocked out, contact your dentist immediately. If it is after hours, she suggested the ToothSOS app for guidance.

She added another major key to dental hygiene for kids over the summer is a consistent schedule.

"Summer oftentimes is going to change that routine but your brushing, flossing routine does not need a change," Kalaskey recommended. "You still want to do brushing twice a day, flossing at least once a day. So kind of making sure we incorporate that, even though the kids might be waking up at 10 o'clock."

Kalaskey emphasized routine is also important for dental visits. She advised children should be seen by a dentist when they get their first tooth and then every six months afterward. In addition to keeping teeth healthy, she stressed it also builds a good relationship with dental visits in the long term.

A Virginia community health center is part of a program addressing food scarcity.

The National Association of Community Health Centers' 2024 Innovation Incubator creates ways to expand healthy food access. Tri-Area Community Health Center's Laurel Fork location will have funding and guidance from experts to help them design and test community-based solutions.

Merrill Warschoff Press, senior vice president of partnership, development and innovation for the National Association of Community Health Centers, said the centers are uniquely suited to address local food issues.

"Health centers are highly effective and innovated with integrated models of care," Press explained. "They reach far beyond the walls of the traditional exam room, not only to prevent illness and treat it but to really address the social drivers that may cause poor health."

Food insecurity has grown since pandemic-era programs ended in 2023. Emergency allotments provided SNAP recipients with an added $95 per month for 470,000 families statewide. However, some people are above or below SNAP's qualifying threshold.

Other issues stem from food prices. The Consumer Price Index shows food prices grew between 2022 and 2023 but in recent months, prices have been declining.

A primary goal of the Innovation Incubator is to discover best practices for providing care for millions of people and share them with health centers nationwide. Press noted the methods being worked out can help varying populations.

"There are many health centers who have large populations of patients who come from other countries and are used to certain foods, and have different preferences," Press observed. "Being able to work with them in their own language with the foods that they like and trust is really valuable to improving access to food that'll make a difference in their lives."

Food pantries have been key to reducing food insecurity wherever possible. Virginia food banks saw a 5% to 10% increase in demand at the end of 2022, which is problematic since food banks nationwide are seeing donations decline and reduced commodities from the Emergency Food Assistance Program.

A southeast Arkansas healthcare system is using grant money to help increase its patients' access to healthy foods.

Mainline Health Systems will use the funds to focus on healthy eating habits for people who are expecting.

Work will include showing families how to grow their own fruits and vegetables, and establishing farmers markets that cater specifically to the needs of pregnant women and new mothers.

Health System Registered Dietitian Jane Pelkki said they will teach new moms the basics of eating healthy.

"Eating healthy doesn't have to cost a lot, that it's doable and that there are food assistance programs such as WIC and SNAP, food stamps," said Pelkki. "And we're also going to provide some food to help moms understand what a healthy meal looks like."

Mainline is one of eight health systems nationwide to participate in the National Innovation Incubator program.

It's sponsored by the National Association of Community Health Centers and the global healthcare company, Abbott.

Research shows almost 13% of U.S. households experience food insecurity - or don't have access to an affordable, nutritious diet.

Merrill Warschoff-Press - senior vice president at NACHC - said the facilities play an integral part in improving the overall health of patients, and address social issues that may cause illnesses.

"They reach far beyond the walls of the traditional exam room, not only to prevent illness and treat it, but also to really address the social drivers that may cause poor health," said Warschoff-Press, "so whether it's food insecurity and poor nutrition or even housing, joblessness, mental illness, substance use disorders."

At the end of the six-month pilot program, results will be shared with 1,400 health centers nationwide. That could impact the overall health of more than 31 million patients across the country.
