#mosquito-borne diseases

[thoughtlessarse]

Mosquito-borne diseases are spreading across the globe, and particularly in Europe, due to climate breakdown, an expert has said. The insects spread illnesses such as malaria and dengue fever, the prevalences of which have hugely increased over the past 80 years as global heating has given them the warmer, more humid conditions they thrive in. Prof Rachel Lowe who leads the global health resilience group at the Barcelona Supercomputing Center in Spain, has warned that mosquito-borne disease outbreaks are set to spread across currently unaffected parts of northern Europe, Asia, North America and Australia over the next few decades. She is due to give a presentation at the global congress of the European Society of Clinical Microbiology and Infectious Diseases in Barcelona to warn that the world must be prepared for a sharp uptick in these diseases. “Global warming due to climate change means that the disease vectors that carry and spread malaria and dengue [fever] can find a home in more regions, with outbreaks occurring in areas where people are likely to be immunologically naive and public health systems unprepared,” Lowe said.

Out of Tune

An irritating warning of itchy bites to come, the high-pitched whine of mosquitoes flying nearby is unmistakable – and not just to humans. To find potential mates, male mosquitoes detect the specific frequency of sounds made by the buzzing of female wings, a feature researchers are hoping to exploit to control mosquito populations. Inside the ears of Aedes aegypti mosquitoes (pictured, with neurons in magenta, in males on the left, females on the right), several neurotransmitters pass on signals to enable sound detection, including serotonin (in green). Changing serotonin levels affects the way male ears respond to different frequencies, and feeding them a serotonin inhibitor reduces male attraction to female buzzing, suggesting that serotonin signalling is critical for functional hearing. Continuing to investigate ways of disrupting this process, that specifically target mosquitoes and can be deployed in the real world, could yield new weapons in the global fight against mosquito-borne diseases.

How to Get Rid of Mosquitoes

Mosquitoes are more than just a nuisance – they can completely ruin your ability to enjoy the outdoors during spring and summer. Their unrelenting biting and buzzing can make your backyard unusable. Even more alarmingly, certain species like the Aedes aegypti mosquito can transmit dangerous diseases such as Zika virus, dengue fever, chikungunya and yellow fever. Luckily, there are many highly…

"Massachusetts towns on alert over potentially deadly mosquito-borne virus. Ten Massachusetts counties are at high or critical risk from the mosquito-borne virus eastern equine encephalitis, a rare but potentially deadly virus, state health officials warn.

The big picture: There are currently no vaccines or medicines available to treat EEE, also known as "Triple E," which about 30% of people die from, according to the Centers for Disease Control and Prevention. "[M]any survivors have ongoing neurologic problems," per an online CDC post. "

One person in New Hampshire has died from eastern equine encephalitis (EEE), a rare illness transmitted by mosquitoes. Europe, meanwhile, is seeing a rise in several more common illnesses. One of the latest mosquito-borne illnesses to put officials on alert is one that is rare yet serious, with some saying it could in the future spread more widely in the United States. One person died in the state of New Hampshire, officials said last week, after testing positive for eastern equine encephalitis virus (EEEV), a mosquito-borne illness native to North America and the Caribbean. There are an average of just 11 cases of the infection reported in the US each year, according to the Centers for Disease Control and Prevention (CDC), and there have been five cases of EEE in the country so far in 2024 in the states of Massachusetts, New Hampshire, Vermont, New Jersey, and Wisconsin. In 2023, there were seven reported cases. […] Rise of mosquito-borne illnesses in Europe Mosquito-borne illnesses also have health officials on alert in Europe, with West Nile virus and dengue, in particular, spreading. While a large majority of West Nile infections are asymptomatic, fewer than one per cent of people infected can develop neurological complications such as meningitis, which is inflammation of the spinal cord and membranes around the brain, or encephalitis. While European countries have had cases of West Nile since the 1960s, the number of infections has increased over the last 15 years, according to the French Pasteur Institute. Since the beginning of the year, 13 European countries have reported human cases of West Nile. Late last year, the EU Food Safety Authority (EFSA) said cases of West Nile had a more than sevenfold increase in 2022 due in part to outbreaks in Italy and Greece. The European Centres for Disease Prevention and Control (ECDC) added in mid-August that the number of cases in 2024 was within the expected range, even though cases were higher in Greece and Spain than in previous years. Like eastern equine encephalitis, mosquitoes become infected with West Nile virus by feeding on birds. However, humans do not have high enough concentrations of the virus to transmit these viruses to mosquitoes when they bite a human. This is different from other mosquito-borne illnesses, where humans can amplify the impact of the virus.

I usually feed Odyssey in the evenings (just cus that's how my schedule usually shakes out) and when I drop his food in, he ALWAYS slams it full force like he has to kill it. Anyway I fed him later than usual a couple nights ago and when I dropped the food in he didn't hop off his perch to get it. And I was IMMEDIATELY like "oh no he's sick, he's dying, this is a Symptom, my BOY,," (bc illness symptoms in raptors are often rapid-onset)

But he finally (carefully) hopped to the ground from his perch and walked over to the food and I realized that it was just slightly too dark outside for him and he was uncomfortable flying. Lmao
