Air Quality Alert continues Friday amid Lollapalooza, festivals in Chicago
Anyone heading there later should be aware that, as far as temperatures go, it will feel about the same as Thursday, but it will be hazy, and the air quality will be worse.
It's all because of the Canadian wildfires. As of Friday, Chicago is in the top five for the worst air quality index of any major city in the world.
The public is advised to take precautions, especially those sensitive to polluted conditions, by limiting their time outside and keeping windows and doors closed.
The poor air quality comes during an eventful weekend, with Lollapalooza drawing tens of thousands of people to Grant Park and Fiesta del Sol bringing out even more people in Pilsen. The cooler temperatures are also keeping people out longer.
For those attending those events or any other outdoor event around the city, Dr. Justin Fiala of Northwestern Medicine recommends adding a mask to your to-go kit.
"What we would recommend to people ultimately is that if they're trying to limit the time they might be outdoors or if they're going to be outdoors for longer periods of time, consider things like N95 or KN95 masks, which are made to filter out 95 percent of these really small particles," he said.
The Air Quality Alert will remain in effect until Friday night.
Organizers at Lollapalooza said they have six medical tents inside the park to help if anyone needs medical assistance.

Mom says infant may have rare tick-borne disease
A Massachusetts mom says her infant daughter may be the patient that state health officials recently said is under investigation for contracting a rare tick-borne virus infection. "Public health officials are investigating preliminary results of a Powassan virus infection in a Martha's Vineyard resident," Barnstable County said in a press release Tuesday, without identifying the resident. Barnstable County, which comprises the 15 towns of Cape Cod and sits just north of Martha's Vineyard, said that according to data from the Centers for Disease Control and Prevention, there has been just one other known case of Powassan virus in the area in the last 20 years and only three total Powassan virus cases in Massachusetts this year. The CDC notes there are currently 24 reported Powassan cases nationwide. Tiffany Sisco, who declined to be interviewed by ABC News, told Boston ABC station WCVB that she found a tick on her 5-week-old daughter Lily Belle Sisco during an outdoor walk, and despite removing it, she noticed Lily developed symptoms a week later. "I found this tiny, tiny, tiny [tick], the teeniest one on her ankle," Sisco said. "I picked it off. A week later, she started getting a fever of 102 [degrees Fahrenheit]. I said, 'I'm taking her right in.'" What is the Powassan virus? Powassan virus is a disease or illness caused by the Powassan virus and is mostly spread by infected ticks that have the Powassan virus or deer tick virus, according to the CDC. The ticks may get infected when they feed on other animals that have the virus, such as groundhogs, mice, squirrels or other rodents. ER visits for tick bites near record levels this summer across US Although considered rare, the CDC notes that Powassan infections have been increasing in recent years, with most infections occurring in northeast states and the states around the Great Lakes region in the spring and fall, when ticks are most active. The Powassan virus can also be transmitted by blood, so anyone who has the virus should not donate blood or bone marrow for at least 120 days after infection. What are the symptoms of Powassan virus and how is it treated? Symptoms of Powassan virus include headache, fever, vomiting and weakness, according to the CDC. The virus can also cause severe disease, the agency states, including inflammation of the brain or inflammation of the membranes around the brain or spinal cord. Symptoms of a severe infection may include confusion, loss of coordination, trouble speaking, and seizures. Some people, such as children, older adults and people with weakened immune systems, may be at higher risk of developing severe symptoms. People with Powassan virus may require fluids, pain medications and rest to alleviate symptoms, but anyone with severe disease may need to be admitted to a hospital for further treatment. What to know about tick-borne illnesses How to prevent tick-borne illnesses There are currently no medications or vaccines to prevent a Powassan virus infection, according to the CDC. However, there are precautions you can take to protect you and your family from tick bites and any subsequent infections. These include: Applying EPA-registered insect repellents. Wearing long-sleeved clothing and pants. Avoiding bushy and wooded areas. Checking for ticks thoroughly and remove any after spending time outdoors. The CDC also advises treating outdoor clothing and gear with products containing 0.5% permethrin, an insect repellent, which will "remain protective through several washings."

More than 400 indirect deaths linked to LA wildfires, study suggests
More than 400 additional deaths are estimated to be linked to the wildfires that ravaged Los Angeles earlier this year, according to a new study. The figure, published on Wednesday in the medical journal JAMA, looks at deaths that have been attributed to factors caused by the wildfires, like poor air quality and delays in accessing healthcare. It is a higher figure than the official death count of 31 by the Los Angeles County, which tallied deaths caused directly by the fires. The study comes as hundreds of wildfires burn across the US and Canada, prompting air quality advisories in cities like Chicago, Buffalo and New York. The Palisades and Eaton fires tore through Los Angeles in January, destroying thousands of structures and leading to the evacuation of more than 100,000 Los Angeles residents. Why wildfires are becoming faster and more furious The far-reaching impacts of wildfire smoke – and how to protect yourself The latest study revealed that around 440 people are estimated to have died as a result of the wildfires between 5 January and 1 February. Researchers said they tallied the figure by looking at all deaths and their causes in Los Angeles during the period of the fires, and comparing it to similar data from previous years. The results show that there were nearly 7% more deaths during the wildfires. Some are attributed to lung and heart conditions exacerbated by smoke or stress, while others are more indirect - like delayed healthcare treatment for dialysis or cancer patients as a result of fire-related disruptions. The authors said that the findings underscore the need for officials to count both direct and indirect fatalities of wildfires and other climate-related emergencies when trying to quantify their impact. "They also highlight the need for improved mortality surveillance during and after wildfire emergencies," the authors said, noting that their figures are provisional as there may have been additional fire-related deaths beyond the scope of the study. The BBC has reached out to Los Angeles County officials for comment on the study's findings. Another study released on Wednesday in JAMA that looked at the aftermath of the 2023 Maui wildfires showed that 22% of adults in the region had reduced lung function, and half displayed symptoms of depression. The fires, which broke out in August 2023 and were the worst to affect Hawaii in recent history, killed at least 102 people and destroyed more than 2,000 structures. The authors of the Maui study said their results show the need for "sustained clinical monitoring and community-based mental health supports" months after a climate disaster. A second study on the Hawaii fires suggests that Maui saw the highest suicide and drug overdose rates in the month of the 2023 wildfires. Wildfires have become more frequent in recent years as a result of climate change, driven by hotter and drier weather that fuels fire spread. In addition to directly threatening lives and structures, smoke from wildfires has been shown to have adverse health effects on people. Wildfire smoke has been found to be harmful to certain immune cells in the lungs, with a toxicity four times greater than particulates from other types of pollution. This can have a long-term impact on cardiovascular health, experts have said. Older people, pregnant women and young children, as well as those with underlying health conditions, such as heart disease or asthma, are more likely to get sick, experts say. But the smoke can also impact healthy adults.

What's slimy, green and flourishing thanks to climate change?
If you guessed algae, you're right. New research published in Communications Earth & Environment suggests algae growth is increasing in Canada's lakes — even remote ones — and climate change is the main culprit. A team led by researchers at McGill University in Montreal and Université Laval analyzed sediment cores taken from 80 lakes across the country and found that algae has been increasing in the majority of them since the mid-1800s. For lead author Hamid Ghanbari, the most interesting finding was a spike in the rate of the increase in algal growth: since the 1960s, it increased sevenfold. "This was something very surprising for us and when we compared our data with other historical records, we found out that rising temperature is a major factor," Ghanbari said. Aside from climate change, excess nitrogen and phosphorus can also contribute to algal growth when they are carried into waterways through runoff from animal manure and chemical fertilizers, stormwater and wastewater. Algae, along with bacteria and phytoplankton, are essential for the aquatic food web. But too much algae can be a bad thing. The recently published peer-reviewed study looked at algal growth overall and didn't analyze for blooms. While some lakes see some algae as a part of their cycle, Ghanbari said the concern is what will happen if the increase in algae leads to growth outside of what's normal. "That's where the problem starts," he said. "We don't know at the moment what that threshold is, but we know the increasing chlorophyll or algae levels in the lakes could lead to several problems." Ghanbari said excess algae growth can harm aquatic life and even human health — reducing water quality, depleting oxygen in the water and creating blooms that can release dangerous toxins, as residents along the shores of Lake Erie know all too well. Daryl McGoldrick, head of water quality monitoring and surveillance for the Great Lakes for Environment and Climate Change Canada, said while increasing algal growth doesn't necessarily mean more toxic blooms, there is a risk to aquatic life. "The study is in line with what we see and [what we] suspect are impacts of warming," McGoldrick said. Global and local action can help Maëlle Tripon, a project manager with Quebec freshwater advocacy group Fondation Rivières, said her team has noticed first-hand that when it's warmer, they see more algae on lakes. She said her takeaway from the research is that tackling algal growth cannot solely rely on local action. "We already knew we need to change locally — like farming practices and also, for example, we need less paved and waterproof surface in the cities," she said. "But what the study shows is that we also need global policies to alleviate climate change." Ghanbari agreed, but added that individual choices can still help reduce algal growth. "Simple acts such as reducing the fertilizers … or properly disposing of household chemicals, these simple acts could really help the lakes," he said.
