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

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.

It's Fall, Which Means It's Time For Gonorrhea! The Flu Isn't Alone: All Infectious Diseases Might Be Seasonal, According To A New Report.

The transition from winter to spring signals the end of months of cold snaps, sweater weather, and Flu Season. But even as the roads clear and flowers bloom anew, it may not yet be time to shelve your sick days for the year.

According to a New Article, published today in the journal PLoS Pathogens, all infectious diseases may be seasonal—and there’s at least one for every time of the year.

Study author Micaela Martinez, an infectious disease ecologist at Columbia University’s Mailman School of Public Health, presents a compendium of 69 infectious diseases that run the gamut from rare to common, neglected to notorious, innocuous to deadly. Despite their differences, all the syndromes have one thing in common: They rise and fall with changing seasons.

Martinez, a conservation ecologist by training, initially set out to track the seasonality of acute, or short-term, infections like influenza and chickenpox after noting similarities between the disease states of humans and wildlife. But as she began to compile a list of infectious diseases that tend to plague humans, Martinez found that the trend also held true for chronic, or long-term, diseases like gonorrhea and leprosy.

“There’s documented seasonality for all infectious diseases, which is not what I was expecting,” Martinez explains. “It’s an even more widespread phenomenon than we thought.”

A quick look at the infectious disease calendar paints quite the sobering picture. As autumn leaves turn from green to red, gonorrhea and yellow fever rear their ugly heads in some parts of the world. The Winds of Winter are Famous For Flu, but also bring bouts of pneumonia. Refreshing springtime blooms breathe new life into outbreaks of chickenpox and salmonella. And last but certainly not least, summer months pack the heat with spikes in Lyme disease, polio, syphilis, tetanus, tuberculosis, and more.

Other diseases are a bit less finicky: They’ll take any period of natural warmth, spreading the joy over many months at a time—often in regions of the world that don’t experience four seasons of climactic change. For instance, Chagas disease, diphtheria, and genital herpes all flourish over both spring and summer, while their prevalence takes a welcome dip when temperatures fall. Other infectious diseases fare better during rainy seasons, or when climes are particularly dry.

Though the diseases she linked together shared little in common, including even their seasons of prevalence, Martinez theorized there might be similar reasons driving their cyclic nature. To tease apart the connections, Martinez amassed data from 100 previously published studies, zeroing in on several factors that shape seasonality.

For instance, environmental factors obviously come into play. Climate conditions such as temperature, humidity, and rainfall impact the wellbeing of infectious microbes, as well as the humans and wildlife they plague. In diseases that are ferried to humans via an insect vector like a Mosquito or fly, the seasonal ebb and flow of these pest populations may also play a role.

The behaviors of hosts of disease, both human and wildlife, also appear to fluctuate from month to month. This has been infamously exemplified by congregations of kids in schools begetting measles outbreaks. But there’s also something to be learned, Martinez says, by studying flux in the habits of non-human animals, who go through bouts of seasonal breeding, territoriality, and migration, and how these changes affect the spread of disease. Humans may not be seasonal maters—at least, not to the same degree—but even a subtle shift, like an uptick in sex during the summer months, could spur outbreaks of Gonorrhea, Genital Herpes, or Syphilis.

“It’s not that we are vulnerable at a particular time of year and healthy at another,” Martinez explains. “We’re restructuring throughout the year. And the identity of the thing we’re vulnerable to changes with the seasons.”

The idea that some infectious diseases are seasonal isn’t new, says Shanthi Kappagoda, an infectious disease physician and epidemiologist at Stanford University who was not involved in Martinez’ work. However, Kappagoda adds, Martinez’ framework is unique in that it includes some infections that haven’t traditionally been considered seasonal—including several sexually-transmitted infections—and may change how clinicians and researchers approach future epidemics.

According to Martinez, knowing when certain diseases are in season could help doctors quickly and effectively treat chronic infections that tend to flare up at certain times of the year, like herpes. With this sort of predictive power, patients may be able to minimize the amount of time they’re forced to deal with seasonal symptoms. The same line of thinking might even be applied to scheduling vaccines, which are ideally administered prior to the onset of an outbreak.

Understanding the drivers of infectious diseases’ seasonality may also be helpful on much broader scales, including the Forecasting of Epidemics Worldwide, adds Amy Wesolowski, an infectious disease epidemiologist at the Johns Hopkins Bloomberg School of Public Health who did not participate in the new analysis.

Such global thinking is especially relevant in a rapidly changing world. As Climate Change progresses, the landscape of infectious diseases will shift, explains Kappagoda. Increasingly warmer locales may favor the transmission of summer-loving diseases like cholera. Humankind may also witness a boom in populations of insects like mosquitoes, which are likely to expand their habitats as temperatures climb, chauffeuring with them outbreaks of Malaria, West Nile Virus, and more. Additionally, human sensitivity to heat shouldn’t be underestimated in the context of infectious disease, Kappagoda points out: Climate change will continue to displace large populations of people, spurring the onset of epidemics.

Whether we like it or not, the spread and severity of infectious diseases are inextricably tied to both biology and behavior—which, in turn, cycle with the seasons. According to Martinez, the implications of this go far beyond fingering a malady for all seasons; rather, these patterns could change how we view our own bodies… and give new meaning to the phrase, “feeling under the weather.”

“This isn’t just about transmission—seasonality is also in the human body itself,” she explains. “There’s something happening in our bodies we don’t quite understand yet. Seasonality in infectious disease is just an enticing little piece of the puzzle.”

I need life to slow down a bit. I have a terrible mass of floaters in my right eye, making it effectively uselss. I can't drive, I can barely see, and tomorrow I have work that requires me to be able to see. Oh, I also got west nile virus, which isn't severe, but boy, am I embodying the definition of sickly. And my wife is out of town, so I'm alone with 3 cats who have decided that devil hour is out. Devil 3 day weekend is in. They're all being bastards.

Sweet baby Leela? Absolute bastard baby.

Hank? He's the real life Christian Devil.

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…

The atypical weather patterns' role in the rise in mosquito-borne diseases in Pune calls for quick attention and coordinated action from all parties involved. Pune is currently observing an alarming increase in mosquito-borne illnesses, which is being attributed to the region's peculiar weather patterns. The rise in instances serves as a sharp reminder of the value of preventive measures and increased public knowledge in order to effectively combat these diseases.Recent temperature and rainfall variations in Pune have diverged from the customary seasonal patterns. These anomalies have made it easier for mosquitoes to reproduce, which has resulted in an increase in the diseases that they spread.

one time me and my friends were talking about our experiences with illness and I mentioned that I had/have Lyme disease and someone said that no I didn't because if I did I would be dead. which, no, that's not how Lyme works. It can cause really really bad issues if left untreated but its not like its immediately fatal or anything???????? where did they even get that from??? and then they refused to admit they were wrong. that was wild lmao

"World Mosquito Day, observed annually on 20th August, is a commemoration of British doctor Sir. Ronald Ross's discovery in 1897 that female anopheline mosquitoes transmit malaria between humans. Serious vector diseases like Malaria, Dengue, Zika, Chikungunya, Yellow fever are spread among humans and animals by an infected mosquito bite.

The world suffers from the vector borne diseases with a yearly estimate of 7, 00, 000 deaths, out of which 4, 00, 000 deaths are contributed to Malaria alone. "
