Measles alert for Perth and the Pilbara
Authorities said the new cases were linked to a cluster that was identified in Perth and the Pilbara last month.
WA Health director of communicable disease control Clare Huppatz said people travelling overseas or to mine sites should check their vaccination status.
'Measles is highly infectious and continues to pose a risk to non-immune people working on mine sites in regional WA,' she said.
Two more measles cases have been identified in WA and are linked a cluster detected in Perth and the Pilbara last month.
'However, international travel is still the most likely source of measles.'
Dr Huppatz said people aged between 30 and 60 years were most at risk and were less likely to have been fully vaccinated or previously exposed to measles.
'This is why I encourage anyone aged between 30 and 60 years, whether you are travelling for work or holidays, to check you are vaccinated against measles.'
Early symptoms include fever, tiredness, cough, runny nose, and sore eyes, followed by a red non-itchy rash three to four days later.
The measles vaccine is free to anyone born after 1965, offers a high level of protection against the disease, and prevents spread in the community and can be accessed through a GP or pharmacist.
People can check WA Health for the latest exposure sites which included flights between Perth and Bali.
'Early symptoms include fever, tiredness, cough, runny nose, and sore eyes, followed by a red non-itchy rash three to four days later,' Dr Huppatz said.
'The rash usually starts on the face and spreads to the rest of the body and people usually feel very unwell.'

How common are Irukandji jellyfish and what are the risks?
They may be tiny, but Irukandji jellyfish can pack a fatal punch. Residents in Western Australia's far north know to be wary of jellyfish stings, especially during the wet season from November to April. But an "unusual" sting at Broome's tourist hot spot Cable Beach in late July has sparked the interest of overseas academics at the University of Hawaii, who will do further research into the species. WA Country Health Service would not release information on the latest patient's condition. While incidents of Irukandji stings are rare, they can be life-threatening and cause other side effects like feeling an impending sense of doom. The local shire website warns Irukandji jellyfish are typically present during the wet season, but former CSIRO marine biologist and jellyfish expert, Lisa-ann Gershwin, said they frequented Broome waters year-round. "There is a kind of safer season where they are less common … but there's always a chance." When a swimmer is stung at Cable Beach, lifeguards close the beach to swimming and conduct stinger drags, which involves sampling sections of water close to the shore for the presence of jellyfish. Lifeguards identify the jellyfish, and if needed, researchers conduct further studies. But lifeguards don't only conduct stinger drags when an incident occurs. It's a routine precautionary measure done twice daily to ensure safety, according to Shire of Broome manager of environmental health, emergency and rangers Aaron Ahtong. "The lifeguards are constantly monitoring conditions," he said. "So, including the drone patrols, they are doing everything they can to make sure the community is protected." While the Irukandji species is not rare in tropical environments, being stung is uncommon. Mr Ahtong said there were six recorded stings in the past five years. This marks a significant decrease from the findings detailed in the Medical Journal of Australia, Irukandji syndrome in northern Western Australia: an emerging health problem, 20 years ago. The report found 88 people were treated for Irukandji syndrome in Broome between 2001 and 2003. "[Stings] are out of the ordinary, but definitely not rare," Mr Ahtong said. There are 16 known species of Irukandji globally. Dr Gershwin has named and classified 14, including all six found in WA. There are two known types in Broome, including Malo maxima and Carukia shinju. "The body is about the size of a thimble and it's got four super-fine tentacles, as fine as cobwebs, and that one I named Carukia shinju," she said. "Of course, shinju is the Japanese word for pearl." Dr Gershwin said she was surprised to hear about the timing of the latest sting, but not shocked. "They don't read the signs and say, 'No, no, it's not the right season yet.'" Dr Gershwin said a strong onshore wind or a "cracking good storm" would heighten the stinging risk, regardless of the time of year. "The atmospheric and oceanic conditions bring them into the beaches, where tragedy occurs when they make [contact] with people," she said. Short answer — no, but it's worth staying informed. Local rangers and scientists agree that Cable Beach is one of the safest beaches because of the precautionary measures taken. Dr Gershwin echoed the Shire of Broome's sentiment, agreeing the most important detail was that people remained aware. "I think scaring people to say there's always a risk is not as effective as saying, 'There's always a risk, but here's what you can do about it.'" Dr Gershwin advised beachgoers to wear protective beachwear, such as full-length lycra suits or wetsuits, and swim in patrolled areas.

‘Shrinking': Reason you always get headaches
'I just learnt that the reason you get a headache when you're dehydrated is because your brain is actually shrinking due to fluid loss.' Understandably, hearing this sentence immediately stopped my thumb in its TikTok tracks. As a chronically dehydrated person, I was alarmed. If this were to be true, then my brain is probably the size of a dehydrated pea by now. I kept listening intently. 'It's pulling your brain away from your skull, and that irritates the membranes and nerves around your brain,' the woman who just shattered my internal peace continued. For the best lifestyle coverage in Australia — download the app direct to your phone. Why we get headaches when we're dehydrated Yep, it turns out this is genuinely true, and every time we're dehydrated, even a little bit, our brain literally shrivels up. One study found that even short-term fluid restriction (such as 16 hours without water) led to a 0.5 per cent decrease in brain volume. The process has to do with water loss from our brain cells, causing them to contract ever so slightly. As the woman who collectively traumatised the internet explained, when this happens, it causes the brain to pull away from the skull, which can stretch and irritate the membranes around the brain. These membranes have pain receptors, unlike the brain itself, which is why it may trigger a headache in some people. According to Dr Jamie Phillips, Updoc 's Chief Medical Officer and a practising GP, some people seem to be more prone to dehydration-related headaches than others, 'particularly if they already suffer from headaches more generally'. How to rehydrate If this happens to you, you'll be glad to know your brain will return to its normal state after rehydration. Dr Phillips suggests you start rehydrating early if you think your headache is caused by dehydration. 'Taking small sips regularly throughout the day will restore the balance. Water is usually all you need, with sports drinks only really useful after intense exercise or heavy sweating,' he notes. 'If plain water isn't for you, you could add something to make it more attractive to drink – but always be mindful of the potential risk to your dental health and the hidden calories you may be consuming.' If water isn't helping and symptoms continue, it's worth seeing a GP. How to prevent dehydration in the first place If you want to avoid this issue altogether and buying an enormous Stanley drink bottle hasn't helped as a preventive measure (guilty), it's important to learn how much water your body actually needs. 'Your individual hydration needs are exactly that, individual,' says Dr Phillips. 'They are influenced by your build, activity level, environment, and overall health. Know your own body, trust your judgement, and avoid dehydration if you're prone to headaches when dehydrated,' he explains. 'Remember, thirst isn't a reliable indicator of hydration, but your urine is. Aim for urine that's not too dark or odourous.'

Brahman pioneer with Q fever saved by cow tissue heart valves
West Australian cattle pioneer Kathy Lovelock is known by the affectionate nickname "the Brahman lady". But the moniker took on a deeper significance a decade ago, when she had parts of her heart replaced with valves made from cattle tissue, in an effort to treat the effects of Q fever. Ms Lovelock, 80, has devoted most of her life to the cattle industry and has been instrumental in developing the Brahman breed across WA's Kimberley and Pilbara regions. Together with her husband, David Lovelock, she founded Canterbury Brahman Stud in 1972 at New Norcia, a town about 130 kilometres north of Perth. In 2015, they both underwent open-heart surgery to address complications from Q fever infections they had contracted many years before. The disease had caused blockages in their heart valves and, in a twist of fate, cow tissue played an essential role in their treatment. Replacement aortic valves are usually sourced from pig heart tissue, but Ms Lovelock is allergic to pigs, so she and her surgeon were left with no choice but to find an alternative. Ms Lovelock said she believed it was tissue from Brahman cattle that saved her life. "[The surgeon] actually went to California to source a bovine aortic valve, and informed us the tissue for that valve came from cattle in Brisbane," she said. "The way we look at it is Queensland is dominated by Brahman cattle, so if they came from Brisbane or Queensland, it had to be Brahman tissue. "There's a fair chance, in our opinion." Ms Lovelock insisted it was pure coincidence that the cattle she had dedicated her life to breeding ultimately saved it. Although not allergic to pigs, Mr Lovelock also received replacement aortic valves made using bovine tissue from Queensland cattle. They understood that aortic valves sourced from cattle heart tissue would last longer than the pig equivalent. Ms Lovelock said she and her husband contracted Q fever in 1995 while visiting sheep and goat sheds in Sabah, a state of East Malaysia on the island of Borneo. "They thought I had dengue fever because there was no diagnosis for Q fever at the time." Her symptoms included lethargy, a fever and headaches; she said it was like a serious case of the flu. The cause was not identified as Q fever until 2007. Nearly 20 years after contracting the disease and 10 years after undergoing open-heart surgery, Ms Lovelock is again facing challenges. She said her immune system was compromised and her heart valves were "playing up". Having another operation to replace her heart valves is not an option, so she is instead focused on managing her symptoms. Mr Lovelock, on the other hand, is doing "fine" — a contrast Ms Lovelock attributes to taking antibiotics she was allergic to. Q fever spreads when people inhale air or dust contaminated with Coxiella burnetii bacteria from the faeces or birth products of infected animals, and is usually associated with the livestock industry. Ms Lovelock is now urging others in the industry to get tested for Q fever and to get vaccinated if they have not been infected. In July, Ms Lovelock was inducted into the Royal Agricultural Society of WA Hall of Fame for her dedication to and impact on the West Australian cattle industry. She said it came as a total surprise. "It's great to have that recognition," Ms Lovelock said. Looking back over the past 50 years, Ms Lovelock said she was most proud to have the support of her husband and the industry as she worked to progress the Brahman breed. The farming matriarch has been actively involved in the Australian Brahman Breeders Association at both state and national levels, as well as the Cattle Council of Australia, and has made it a priority to inspire young people's interest in the beef industry.
