Bid to track tourist amid fears hundreds could have been exposed to rabies at bat-infested cabins
The widespread alert stems from concerns over bat presence within eight linked cabins at Jackson Lake Lodge. Despite the extensive outreach, as of Friday, none of the bats recovered from these specific cabins and subsequently tested have returned positive results for rabies.
However, Dr. Alexia Harrist, Wyoming State Health Officer, has cautioned that the limited number of dead bats found and dispatched to the Wyoming State Veterinary Laboratory in Laramie for analysis likely represents "only a small sample of the likely dozens that colonized the attic above the row of cabins." She further explained that many other bats were not killed but were simply ushered out through cabin doors and windows, while the vast majority never descended from the attic into the living areas below.
Health officials thus deemed it better safe than sorry to alert everybody who has stayed in the cabins recently that they might have been exposed by being bitten or scratched. Especially when people are sleeping, a bat bite or scratch can go unseen and unnoticed.
'What we're really concerned about is people who saw bats in their rooms and people who might have had direct contact with a bat,' Harrist said Friday.
The cabins have been unoccupied, with no plans to reopen, since concessionaire Grand Teton Lodge Company discovered the bat problem July 27.
Bats are a frequent vector of the rabies virus. Once symptoms occur — muscle aches, vomiting, itching, to name a few — rabies is almost always fatal in humans.
The good news is a five-shot prophylactic regimen over a two-week period soon after exposure is highly effective in preventing illness, Harrist noted.
The cabins opened for the summer season in May after being vacant over the winter. Based on the roughly 250 reservations through late July, health officials estimated that up to 500 people had stayed in the cabins.
They were trying to reach people in 38 states and seven countries through those states' health agencies and, in the case of foreign visitors, the U.S. Centers for Disease Control and Prevention.
Others who have not been alerted yet but stayed in cabins 516, 518, 520, 522, 524, 526, 528 and 530 this year should tell health officials or a doctor immediately, Harrist said.
Health officials were recommending prophylactic shots for people who fit certain criteria, such as deep sleepers who found a bat in their room, and children too young to say that they had seen a bat.
The Wyoming Department of Health had no ongoing concern about visitor safety at the Jackson Lake Lodge area. That includes a Federal Reserve economic policy symposium Aug. 21-23 that takes place at Jackson Lake Lodge every summer.
'The lodge company has done a fantastic job of doing their due diligence of making sure everyone that is coming in for that, and for all other visits this year, are going to be as safe as possible,' said Emily Curren, Wyoming's public health veterinarian.
'Three or four' dead bats from the cabins tested negative and one that was mangled did not have enough brain tissue to be testable, Curren said.
All were brown bats, which come in two species: 'little' and 'big,' with the larger ones more than twice as big. Officials were unsure which species these were, but both are common in Wyoming.
They typically live in colonies of 30 to 100 individuals, Curren said.
'That's a lot of bats that we cannot rule out a risk of rabies being in,' Curren said. 'There's no way for us to know for certain about every single bat that got into these rooms.'
There are no plans to exterminate the bats, Grand Teton National Park spokesperson Emily Davis said. Devices fitted to the building were keeping the bats from getting back in after flying out in pursuit of insects to eat, they said.

Brits warned against sharing towels and razors after spike in MRSA superbug infections outside of hospitals
Brits have been urged to avoid sharing towels or razors amid an increase in cases of MRSA being contracted in the community. Data shows a total of 175 people were infected with the superbug outside of hospitals between January and March this year, up 47 per cent from the same period in 2019. Those catching the infection also appear to be getting younger, with almost a quarter of patients recorded as under 45 in 2023-24 compared to just one in 10 in 2007-08. The UK Health Security Agency (UKHSA) said they are monitoring infection rates closely to understand the underlying drivers. But people are being urged to practice good general hygiene, including regular handwashing and not sharing items like towels and razors. It follows warnings from the US over MRSA being spread in gyms and changing rooms this summer. Officials from the US Centres for Disease Control and Prevention (CDC) said: 'MRSA spreads fast in athletic facilities, locker rooms, gyms and health clubs because of shared equipment and skin-to-skin contact.' MRSA, which stands for methicillin-resistant Staphylococcus aureus, is a bacteria that lives harmlessly on the skin or in the nose. However, it can cause serious infections if it gets into the body. If it spreads to your blood or lungs, symptoms can include chills, difficulty breathing, dizziness and confusion. Rates of the superbug have been steadily increasing in the last decade following a large fall in cases between 2008 and 2012. The UK data does not record where patients contracted the bug outside hospitals. Colin Brown, a director of antimicrobial assistance and healthcare-related infections at the UKSHA, told The Times: 'The overall risk of MRSA bloodstream infections to the public in hospital and community settings remains low [and] substantially below the last peak observed in the early 2000s. 'It is too early to conclude whether the current rise represents a sustained shift; however, the trend is being monitored closely through surveillance and analysis to better understand the underlying drivers. 'This will include further analysis of patient characteristics, such as residential type. 'Outbreaks of these infections in community settings can be managed through maintaining good general hygiene, including regular handwashing and not sharing items such as towels and razors.' Andrew Edwards, associate professor of molecular biology at Imperial College London, said those who catch MRSA in hospital tended to be older or already ill. However, younger patients who catch it outside of hospitals are often in sports teams or gym users, which raises 'a few red flags'. 'We need to keep a very close eye on whether we are seeing a lot more community transition of MRSA between otherwise healthy people … and watch to see whether this is a blip in the numbers or the beginning of a worrying new trend,' he said. He urged gym users to 'check yourself carefully and be aware you might have abrasions that are not immediately obvious - if you do have any, cover those and just be aware.' WHAT IS MRSA? Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria that is resistant to several widely-used antibiotics, which makes it particularly hard to treat. Catching the infection early could prevent it spreading and infecting others. Approximately 30 per cent of people carry the Staphylococcus aureus bacteria even in their nose, armpits, groin or buttocks without realising it. This can invade the body's bloodstream and release poisonous toxins that kill up to one-fifth of infected patients. MRSA is most commonly associated with hospitals. As well as being highly drug resistant, current screening methods are fairly inaccurate, which allows the infection to spread as a patient moves around both within and outside hospitals. Even when the infection is successfully treated, it doubles the average length of a patient's hospital stay, as well as increasing healthcare costs.

Terrifying 'zombie squirrels' with oozing flesh pods on their bodies invade US backyards
Grotesque squirrels covered in oozing sores have been spotted invading backyards in the US, and a common garden object is helping the animals spread their condition. The disfigured squirrels have been spotted in both the US and Canada in recent months, with social media users on both X and Reddit trying to figure out what's wrong with the rodents. The reports date back to 2023, when residents in Maine captured images of common gray squirrels covered in tumors while visiting their backyards. Witnesses have photographed these hairless growths oozing pus covering most of the animals' bodies, from their heads and eyes to their legs, feet, and genitals. While some on social media have suspected that the animals are carrying squirrel pox, a rare virus in the US that mainly affects red squirrels, others have pointed out that the illness is more likely to be squirrel fibromatosis. This condition is caused by a different virus, resulting in wart-like growths that may ooze fluid but usually heal on their own, and is more common in US gray squirrels. In either case, wildlife experts believe homeowners who put bird feeders in their yards may be unintentionally causing the virus to spread to more squirrels throughout North America. Shevenell Webb from the Maine Department of Inland Fisheries and Wildlife said: 'It's like when you get a large concentration of people. If someone is sick and it's something that spreads easily, others are going to catch it.' In November 2024, a Reddit user in the US posted an image of a squirrel covered in tumors consistent with squirrel fibromatosis Squirrel fibromatosis is caused by a virus that cannot be transmitted to people or other animals Squirrel fibromatosis may look terrifying, but it's a common skin disease among gray squirrels in the US. It's caused by the leporipoxvirus and is spread through direct contact between healthy squirrels and the lesions or saliva of infected squirrels, similar to herpes transmission in humans. The disease causes hairless growths or tumors, which can break open and leak clear fluid just like an open wound. Although the virus cannot spread to humans or other animals such as dogs or birds, Webb said people should not touch or attempt to help infected squirrels. 'I would not recommend trying to capture a squirrel that has the virus,' Webb told the Bangor Daily News. 'It is naturally occurring and will run its course in time.' To Webb's point, while the growths can look alarming, they typically heal without the need for medication and are rarely fatal. However, some severe cases of squirrel fibromatosis may affect the animal's internal organs and lead to death. While sightings of infected squirrels date back to the summer of 2023, the most recent cases were posted online less than a month ago. Residents in Canada have also captured images of infected squirrels who were covered in hairless tumors The cases are not believed to be squirrel pox, which generally infects red squirrels and is more common in the UK 'At first I thought it was eating something from my front beds, but then I realized it was on its face,' one Reddit user posted on July 31 after spotting a gray squirrel with a large tumor on its mouth. Wildlife officials noted that sightings tend to rise during the summer when more animals are out gathering food, especially from homes that put out bird feeders. 'Like a lot of people, I love watching birds,' Webb said. 'Unfortunately, you can attract multiple [squirrels] to that feeder and risk exposure if one has the virus.' The expert explained that squirrels with fibromatosis can leave their saliva on uneaten bird seed at these feeders, which healthy animals can then ingest and contract the virus. To this point, wildlife experts have not confirmed whether the new sightings are cases of fibromatosis or squirrel pox (SQPV), but there's less of a chance that squirrel pox is spreading through the US. SQPV is a systemic condition that often results in death among red squirrels, who are more vulnerable to the virus. Moreover, SQPV is more common in the UK, as there are more red squirrels in that country compared to the US and Canada. Fibromatosis tumors typically heal on their own within 2 months and do not return among gray squirrels A similar condition affecting rabbits in the Midwest has prompted many on social media to ask if it would be humane to euthanize animals spotted with these tumors. Just like the rabbits infected with cottontail papilloma virus, causing tentacle-like tumors on their heads, wildlife officials have said that people should leave squirrels with fibromatosis alone. A squirrel's immune system can clear the virus within four to eight weeks, although it may take longer for larger or secondary infections to heal. The condition does not typically come back once a squirrel contracts fibromatosis, and gray squirrels generally recover fully, meaning the horrifying growths won't be visible by the time people see that same animal next year.

Using AI to analyse ultrasound scans lets parents pinpoint exact due date of babies, study claims
Using artificial intelligence to analyse ultrasound scans could give parents the exact day their child will be born with 95 per cent accuracy, a study has claimed. Doctors currently estimate a foetus's due date by adding 40 weeks to the first day of the mother's last menstrual period. This rough calculation is known as Naegele's rule and assumes the woman has a 28-day menstrual cycle and ovulates on day 14, which, for many, is not true. In the UK, just four per cent of babies are born on their due date. But a group of US researchers say using AI to analyse ultrasounds could predict a child's date of birth with 95 per cent accuracy. Using a software developed and trained using more than two million ultrasound images from women who gave birth at the University of Kentucky from 2017 to 2020, the scientists measured how well AI could estimate whether a baby would be carried to term or not. The program, called Ultrasound AI, was able to predict whether a baby would be born early with 72 per cent accuracy, without relying on external information such as maternal history or clinical measurements. It was 95 per cent accurate in predicting the due date of babies carried to full term, and 92 per cent accurate for all births combined. 'AI is reaching into the womb and helping us forecast the timing of birth, which we believe will lead to better prediction to help mothers across the world and provide a greater understanding of why the smallest babies are born too soon,' said Dr John O'Brien, director of maternal-foetal medicine at the University of Kentucky. 'AI will eventually provide greater insights into how to target and prevent adverse pregnancy outcomes 'This work is an important first step in the start of a powerful advance in technology for the field of obstetrics.' Preterm birth is currently the leading cause of neonatal mortality in the world, and one in every 12 babies is born prematurely. It comes after the UK Government last year announced a plan to reduce the number of preterm births from 8 per cent to 6 per cent.
