The Climate Crisis Is a Health Crisis
by Mark Schapiro
May 17, 2023

Introduction:

(Capital & Main) The direct and indirect health impacts of climate change are one of the most underreported aspects of the climate crisis. The medical and scientific journals are filled with examples of diseases shifting along with the shifting climatic conditions, but the links between the environment and personal health rarely make it into the media. In the last column I talked about the direct impacts of greenhouse gases on our health. This time, let’s focus on why the American Public Health Association has determined that the changing climate being wrought by the accumulation of those gases in the atmosphere are triggering a health emergency.

Medical professionals in the U.S., warns the CDC, may be thoroughly unprepared to treat diseases that have been previously confined to tropical Africa and Latin America. The World Health Organization says that climate change presents “the biggest health threat facing humanity.” Bugs and bacteria, it turns out, can adapt much better to a changing environment than we humans.

The scientific press is filled with examples of how the changing climate is opening new pathways for insects following the heat, fungi following the moisture, algal blooms proliferating in warming waters fed by phosphate-based agricultural runoff — and how all are being buffeted by the frequency of the extreme swings in temperature and rainfall.

Start with disease-bearing mosquitoes — whose range is rapidly expanding inside the continental United States. The mosquito family known as Aedes aegypti, most responsible for transmitting diseases like zika, dengue, chikungunya and yellow fever, has largely been limited to the tropics but is following the heat into a broad band across the southern United States, from North Carolina and Virginia into the southern portions of California and Arizona.

Warm, humid conditions and the later onset of winter have also helped spur an expansion in the range of ticks carrying lyme disease for longer seasons in the Northeast, and showing up in greater numbers as far west as California.

The article also discusses the release of sterile male mosquitos as an abatement strategy.

The spread of fungi carrying what’s known as Valley fever is also mentioned. The proliferation of marine bacteria called Vibrio is reviewed. The Vibrio bacteria infects shellfish and is easily transmitted to humans, for whom it can cause digestive and skin ailments.

Three People Have Acquired Malaria in the U.S. They’re the First in Twenty Years
by Keren Landman
June 23, 2023

Introduction:

(Vox) In late May, Sarasota County, Florida, health officials confirmed they had identified a case of locally transmitted malaria. In mid-June, they confirmed the second. On June 23, Texas joined in: its state health department announced it had confirmed a case of local malaria transmission in Cameron County.

This is all highly unusual. The US hasn’t documented a locally acquired malaria case in 20 years.

Although about 2,000 people infected with malaria turn up in the US health care system every year, those cases are all linked to travel outside the US. Neither those involved in the Florida cases nor the Texas case had traveled. That means in both states, the infection was acquired within US borders.

Experts say the three cases shouldn’t warrant panic about widespread malaria transmission in the US. But it does warrant asking some questions, and being wary of the threat of more local transmission. Mosquitoes can infect multiple people before a full-on outbreak is even identified — so more cases could be out there.

Even if this turns out not to be widespread, it’s a good reminder: Malaria could make a comeback in the US, and we — and our public health infrastructure — ought to be prepared. This is especially true as a changing climate and shifting weather patterns increasingly drive mosquito migration into new places worldwide, allowing malaria to settle in where it hasn’t before.

Malaria cases in Texas and Florida are the first U.S. spread since 2003, the CDC says
Source: NPR

Five cases of the mosquito-borne infection malaria have been detected in the United States in the past two months, marking the first local spread in the country in 20 years.

Four of the cases were found in Florida, while the fifth was logged in Texas, according to the Centers for Disease Control and Prevention. The cases are believed to be locally acquired, a statement from the organization read, though the developments pose a concern for a potential rise in imported malaria cases with increased international summer travel.

Malaria, which is mostly found in tropical countries, can be life-threatening but is preventable and curable. The World Health Organization says in 2021 there were an estimated 247 million cases of malaria worldwide. Of those cases, an estimated 619,000 people died from the disease. And it could get worse around the world, according to a scientific study published by The Lancet in 2021, which found that climate change will increase the suitability for both malaria and dengue, another mosquito-borne illness.

"Rising global mean temperature will increase the climatic suitability of both diseases particularly in already endemic areas," according to the study's authors. "The predicted expansion toward higher altitudes and temperature regions suggests that outbreaks can occur in areas where people might be immunologically naive and public health systems unprepared."

Wisconsin Republicans block meningitis vaccine requirement for students
https://apnews.com/article/republicans- ... 96f7e583c7

MADISON, Wis. (AP) — The Republican-controlled Wisconsin Legislature on Wednesday voted to stop Democratic Gov. Tony Evers’ administration from requiring seventh graders to be vaccinated against meningitis.

The state Senate and Assembly, with all Republicans in support and Democrats against, voted to block the proposal. There is no current meningitis vaccination requirement for Wisconsin students.

The Legislature’s vote also makes it easier for parents to get an exemption from a chicken pox vaccine requirement that is in place for all K-6 students. Evers’ administration wanted to require parents seeking a chicken pox vaccination exemption to provide proof that their child has previously been infected.

Families could still seek waivers from the meningitis vaccination and chickenpox proof requirements for medical, religious or philosophical reasons, just as they can for other vaccinations.

The Advisory Council on Immunization Practices — experts who advise the Centers for Disease Control and Prevention — has recommended that students get vaccinated against meningitis since 2005.

On Preventing Zoonotic Disease
by Viola Savy Dsouza and Sanjay Pattanshetty
July 10, 2023

Introduction:

(Eurasia Review) Zoonotic diseases, diseases that can be transmitted between animals and humans, pose a significant burden on global health. These diseases encompass a wide range of pathogens, including bacteria, viruses, and parasites, that can cause death in both humans and animals.

Every year, 6 July is observed as “World Zoonoses Day”. This day aims to shed light on activities to raise awareness about zoonotic diseases and their prevention. It is estimated in the year 2017 that zoonoses are responsible for 2.5 billion cases and 2.7 million mortality rate worldwide. There are over 200 known types of zoonoses.

According to estimates, around 70 percent of newly identified human diseases are zoonotic, meaning they originate from wildlife or spread through infection from domesticated animals. As the frequency of zoonotic outbreaks seems to be on the rise, it is essential to understand the factors that contribute to these outbreaks to effectively prevent the risks associated with zoonotic diseases. Given the scale of the problem, an intersectoral approach is needed to address the complex factors contributing to zoonotic disease transmission and emergence and their impact on human, animal, and environmental health.

The COVID-19 pandemic has emphasised the need for a more integrated and proactive approach to zoonoses prevention.

Frozen Pathogens Are Waking Up, And Scientists Say the Risk Is Real
by Corey J.A. Bradshaw & Giovanni Strona
July 28, 2023

Introduction:

(Science Alert) Could pathogens that were once common on Earth – but frozen for millennia in glaciers, ice caps and permafrost – emerge from the melting ice to lay waste to modern ecosystems? The potential is, in fact, quite real.

Dangers lying in wait

In 2003, bacteria were revived from samples taken from the bottom of an ice core drilled into an ice cap on the Qinghai-Tibetan plateau. The ice at that depth was more than 750,000 years old.

In 2014, a giant "zombie" Pithovirus sibericum virus was revived from 30,000-year-old Siberian permafrost.

And in 2016, an outbreak of anthrax (a disease caused by the bacterium Bacillus anthracis) in western Siberia was attributed to the rapid thawing of B. anthracis spores in permafrost. It killed thousands of reindeer and affected dozens of people.

Conclusion:

While the likelihood of a pathogen emerging from melting ice and causing catastrophic extinctions is low, our results show this is no longer a fantasy for which we shouldn't prepare.

This is why you shouldn't defrost or mess around with pathogens/organisms from the past as you don't know what you will end up with or may kill off humanity because of it.

[Ken_J]

This is why you shouldn't defrost or mess around with pathogens/organisms from the past as you don't know what you will end up with or may kill off humanity because of it.

with viral illness and some bacterial, fungal and other single celled entities, the older it is the less likely it is to be able to infect humans, and the more likely it is to be vulnerable to common antibiotics.

the real threat from most pathogens is massive damage to the food change and ecosystem balance.

imagine the irish potato famine, and the vulnerability of banana crops to single illnesses, but instead it effects wheat, rice or other grains.

imagine how bad it would get if something bird flu swept through the beef production industry.

those are just our food supplies, now imagine something like the major wildfires but biological sweeping through whole forests and killing trees by the 100s of acres. or something that kills fish in the waterways like biblical plague, leaving predatory fish and whales and dolphins with famines.

we already strain the ecosystem too much, a simple infection could absolutely collapse it completely, driving life on earth back to the simplest and heartiest options.

Life's a b****.
Not that humanity isn't either.
