Legionnaires' disease cluster in New York City causes a 4th death, sickens over 100 people. What is it, and how do you get it?
A fourth person has died, and over 100 people have been sickened with Legionnaires' disease — 15 of them currently hospitalized — amid an outbreak in central Harlem in New York City, health officials said Thursday.
The disease was initially detected on July 25. Since then, the New York City Department of Health has been investigating the cluster and linked it to 12 cooling towers in 10 Harlem buildings. Cooling towers are structures containing water and a fan that are used to regulate a building's temperature.
Eleven of the 12 cooling towers that tested positive for the bacteria that cause Legionnaires' disease have been remediated, with the last one currently undergoing remediation, acting Health Commissioner Michelle Morse said during a Thursday news conference.
Health officials released a list on Thursday that identifies the 10 buildings connected to the outbreak:
BRP Companies, Lafayette Development LLC, 2239 Adam Clayton Powell Jr. Blvd.
BVK, 215 W. 125th St.
Commonwealth Local Development, 301 W. 124th St.
CUNY — City College Marshak Science Building, 181 Convent Ave.
Harlem Center Condo, 317 Lenox Ave.
NYC Economic Development Corporation, 40 W. 137th St.
NYC Health Department Central Harlem Sexual Health Clinic, 2238 Fifth Ave.
NYC Health + Hospitals/Harlem, 506 Lenox Ave.
The New York Hotel Trades Council Harlem Health Center, 133 Morningside Ave.
Wharton Properties, 100 W. 125th St. (three of eight towers)
Overall, the following ZIP codes have been affected in Harlem: 10027, 10030, 10035, 10037 and 10039.
'We are continuing to urge all New Yorkers who live or work in the identified ZIP codes in central Harlem who have flu-like symptoms to contact a health care provider immediately,' Morse said.
'New Yorkers should know the air is safe to breathe, and we are seeing declining numbers of new cases each day,' New York City Mayor Eric Adams told the media. 'I want to thank the health workers who worked tirelessly to treat this community and make sure its residents are healthy.'
What is Legionnaires' disease?
It's a serious type of pneumonia, a lung infection, that is caused by Legionella bacteria.
People can become sick from inhaling water vapor that's contaminated with Legionella bacteria. Less commonly, a person can get sick when water contaminated with the bacteria accidentally enters the lungs by aspiration.
How does it spread?
In general, Legionnaires' is not transmitted from person to person. Legionella can grow and spread in human-made water systems like showerheads and sink faucets, hot tubs, decorative fountains, complex and large plumbing systems and cooling towers, according to the Centers for Disease Control and Prevention.
There are also factors that make it easier for Legionella to grow and survive in water, including:
Biofilm, which is slime that enables germs to grow
Temperatures from 77 degrees to 113 degrees Fahrenheit
Not having enough disinfectant
Slow or no water movement (read more from the CDC about how to prevent waterborne germs while away from your home)
What are the symptoms of Legionnaires' disease?
Symptoms usually appear in a person within two to 14 days after they've been exposed to the bacteria, the CDC says. Symptoms can be similar to other types of pneumonia, such as:
Headache
Muscle aches
Shortness of breath
Cough
Fever
Other symptoms can include confusion, diarrhea or nausea.
Who is at risk of getting sick?
Most healthy people exposed to Legionella don't become ill, according to the CDC's website. However, the following people are at increased risk of getting sick from the bacteria:
People 50 years and older
Current or former smokers
People with specific health issues or conditions, like cancer, chronic lung disease, diabetes, kidney failure, liver failure and a weak immune system
Diagnosis and treatment
A chest X-ray can confirm if a person has pneumonia. But additional tests are needed to confirm if Legionella bacteria is the cause behind it, such as a urine test, or a lab test involving a sample from phlegm (sputum) or lung lavage (lung washing), according to the CDC.
The disease is treatable with antibiotics, but hospital care is often needed.

Follow the '1-set rule,' eat popcorn, brush your teeth before breakfast — plus 5 more health tips to help you have a great week
Popcorn has healthy fiber, making it a great snack, experts say. Hello, health enthusiasts! My name is Kaitlin Reilly, and I'm here to round up this week's best wellness tips. Are you drinking less these days — or just more carefully considering how much you imbibe? If so, you're not alone: A recent Gallup poll found that many Americans are rethinking their relationship with alcohol. Today 53% of U.S. adults say moderate drinking is bad for your health, compared with just 28% in 2015. The increase is driven largely by young adults, but older adults are also more likely than ever to view even one or two drinks a day as risky. That leads to less drinking overall, with the Gallup poll finding that reported drinking by Americans was among the lowest in decades. What could be behind this change? It may have to do with shifting guidelines and attitudes around imbibing from public health officials. In January 2023, the World Health Organization officially stated that no amount of alcohol is safe for our health — and more recently, former U.S. Surgeon General Dr. Vivek Murthy stated that he wanted to place cancer warning labels on alcohol. That's a stark contrast from the beliefs many held about alcohol, including that a moderate amount of red wine was good for your heart. Drinking less can be good for your health: Alcohol disrupts your sleep, gut health and liver function. At a party and want to indulge? Consider swapping every other drink for water or having a low-sugar mocktail to reduce your overall consumption. Looking at the week ahead? Peek at your local weather forecast, then check out your horoscope if you're so inclined. Finally, find your 'one small thing' to do this week to improve your well-being. Here are some ideas. 🍿 Swap chips for popcorn If you crave salty snacks, swap out a bowl of potato chips for some air-popped popcorn, experts tell Eating Well. While both provide that salty crunch, popcorn has a nutritional leg up. 'Popcorn is a whole-grain snack packed with insoluble fiber, which adds bulk to stool and helps food move more efficiently through the digestive track,' dietitian Jessie Wong says. Plus, popcorn contains polyphenols, compounds that have antioxidant properties. Just skip drowning yours in butter, which adds extra saturated fat and calories. Instead, add some flavor by sprinkling on spices like cayenne pepper, cinnamon or even some nutritional yeast. 🕔 Eat dinner at this time The best time to eat dinner depends on when you're going to bed, with experts telling Prevention that you should aim to eat at least two to three hours before you hit the hay to help with digestion and get a better night's sleep. That's because as you get closer to bedtime, the body becomes 'less efficient at handling sugar, so late meals can lead to higher blood sugar and may disrupt sleep in some people,' dietitian Michelle Routhenstein explains. Plus, research has shown that people who eat dinner earlier are more likely to lose weight, while people eating later are more likely to gain it. Still feel hungry post-dinner? Go for a light, plant-based snack, experts recommend, and try to eat it at least one hour before you hit the pillow. Some good options are pistachios or cherries — they both contain melatonin, a hormone that regulates sleep. 🏋️ Do 'just one set' at the gym Become more efficient at building muscle by following this tip from Tom's Guide: Do just one set at the gym. New research published in the journal Medicine and Science in Sports and Exercise found that individuals could build muscle by doing just one set of each exercise twice a week as long as they worked close to muscle failure each time. So, instead of eeking out a bunch of reps over multiple sets, focus on lifting as heavy as you can while still maintaining proper form, so you can burn out in just one go-round. You'll save time while still making gains. 🤳 Leave your phone outside your bedroom Dr. Craig Canapari, a pulmonologist and director of the Yale Pediatric Sleep Center, recently shared his list of tips for getting the best night's rest with Today. An easy one that you can follow right now is to leave your phone outside the bedroom, especially if you're prone to scrolling before shutting your eyes. Apps like TikTok could be keeping you awake, Canapari says, because they're 'calibrated to give these really short bursts of media back to back and tend to be incredibly engaging and difficult to unplug from.' Want to wind down? Try reading a book instead, or even engaging in a meditation practice. 🪥 Brush your teeth before breakfast It's an age-old debate: Is it better to brush your teeth before or after breakfast in the morning? Our friends at Women's Health spoke to dentists who have the answer: Brush right after you wake up, before you have anything to eat or drink. Not only will it squash 'horrible morning breath,' dentist Steven Katz says, but it will also 'remove the plaque and bacteria that developed overnight.' Plus, dentist Anjali Rajpal says that brushing with toothpaste before you eat protects your teeth from acid (like in a morning glass of OJ) by coating your teeth with 'protective fluoride, hydroxyapatite, calcium phosphate or other minerals.' 🏃🏿♀️➡️ Work out twice a week Only have time to work out a couple of days a week, like on the weekend? That's OK, according to research in the Annals of Internal Medicine. Women's Health reports that the study, which looked at individuals with type 2 diabetes, found that so-called weekend warriors still significantly lowered their risk of dying from heart disease when compared with those who didn't exercise at all. This follows previous research that shows that exercising on weekends offers the same reduced risk of 264 diseases as sweating it out during the week. While staying active as often as you can is ideal, if you're strapped for time, squeeze in as much exercise as you can when you have a few free hours: Go for a spin class or hike with friends instead of brunch, or run around with your kids at a park instead of heading to the movie theater. 🥫 Pick healthier versions of ultra-processed foods Ultra-processed foods have a bad rap — and for good reason. But a new report from the American Heart Association says not all of them are the same. While the organization recommends cutting back on these types of foods — think highly processed meats like hot dogs and sausages, as well as packaged cookies, chips and pastries — healthier options include 'certain whole grain breads, low-sugar yogurts, tomato sauces and nut- or bean-based spreads.' Overall, though, the problem with ultra-processed foods is that they can contain high amounts of fat, sugar and sodium and not enough nutrients, CNN reports. Keep them as a minimal part of your diet by picking whole foods like vegetables, fruit, nuts, eggs and fish whenever possible. 🙆 Practice wall Pilates Wall Pilates is exactly what it sounds like: Pilates you do against the wall — and as Women's Health reports, it's surprisingly challenging. The movements are based on the ones you'd find in a traditional Pilates class, except using a wall to improve stability, support and resistance. One move to try at home is the 'roll-up,' in which you lie on your back with feet flexed against a wall and arms overhead. Exhale as you curl up and reach toward your toes, then repeat for eight reps at a time. Your abs may burn, but you'll get stronger with every move. Solve the daily Crossword

Why Do Screens Keep You Up? It May Not Be the Blue Light.
Experts have long warned about the dangers of blue light before bed. When exposed via smartphones, TVs, laptops and other devices, our brains suppress the production of the hormone melatonin, which normally makes you feel drowsy. As a result, you feel more alert, making it harder to fall — and stay — asleep. But the link between blue light and sleep is murkier than we thought, said Lauren E. Hartstein, an assistant professor of psychiatry at the University of Arizona. She and other researchers have been taking a closer look at the evidence, which suggests that blue light alone may not be causing poor sleep. And in some cases, screen use could even help you drift off. Here's what studies on blue light actually suggest — and what may help you sleep more soundly. Research on blue light and sleep is mixed. Many of the available studies on blue light and sleep are old and are limited by their small sample sizes. They were also often performed in carefully controlled laboratories, so their results don't always reflect real life, Dr. Hartstein said. While it's true that blue light exposure can sink melatonin levels, the limited evidence we have suggests that screen use does not always cause this dip, said Mariana Figueiro, a scientist at the Icahn School of Medicine at Mount Sinai in New York City who studies how light influences health. Some of Dr. Figueiro's research suggests, for instance, that how long you use your device for, how close it is to your eyes and how bright it is may play a role. One of her studies from 2013 found that using an iPad at full brightness for two hours caused melatonin levels to drop slightly, whereas using it for one hour caused no change. Another study from 2014 concluded that watching television from nine feet away had no effect on melatonin levels. And using an iPad at a higher brightness level may suppress melatonin more than using it at a lower brightness level, according to a 2018 study. What you do during the day may also influence screen-related melatonin drops at night. The more bright sunlight you're exposed to during the day, some research suggests, the less susceptible you may be to an evening dip. Want all of The Times? Subscribe.

Wildfire Fighters, Unmasked in Toxic Smoke, Are Getting Sick and Dying
The smoke from the wildfires that burned through Los Angeles in January smelled like plastic and was so thick that it hid the ocean. Firefighters who responded developed instant migraines, coughed up black goo and dropped to their knees, vomiting and dizzy. Seven months later, some are still jolted awake by wheezing fits in the middle of the night. One damaged his vocal cords so badly that his young son says he sounds like a supervillain. Another used to run a six-minute mile and now struggles to run at all. Fernando Allende, a 33-year-old whose U.S. Forest Service crew was among the first on the ground, figured he would bounce back from his nagging cough. But in June, while fighting another fire, he suddenly couldn't breathe. At the hospital, doctors discovered blood clots in his lungs and a mass pressing on his heart. They gave him a diagnosis usually seen in much older people: non-Hodgkin lymphoma, an aggressive cancer. It would be unthinkable for urban firefighters — those American icons who loom large in the public imagination — to enter a burning building without wearing a mask. But across the country, tens of thousands of people who fight wildfires spend weeks working in toxic smoke and ash wearing only a cloth bandanna, or nothing at all. Wildfire crews were once seasonal laborers who fit in deployments between other jobs. They might have experienced only a few bad smoke days a year and had the winter and spring to recover. Now, as the United States sees more drought and extreme heat, forest fires are starting earlier in the year, burning longer and expanding further. Firefighters often work almost year-round.
