Researchers develop models to predict epidemics of yellow fever, other mosquito-borne diseases

Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to an understanding of how epidemics happen and should be combated. It was introduced to the Americas in the seventeenth century, and high death rates have resulted from successive outbreaks since then. Epidemics of yellow fever were associated with the slave trade, the US gold rush and settlement of the Old West, the Haitian Revolution, and construction of the Panama Canal, to cite only a few examples.

Centuries after the disease was first reported in the Americas, an international team of researchers will embark on a groundbreaking study to develop models that predict epidemics of yellow fever and other diseases caused by mosquito-borne arboviruses such as dengue, zika, and chikungunya.

Deforestation, forest conversion and palm oil | EurekAlert! (“deforestation and afforestation had significant correlations to disease outbreaks”)

Confirming past hypotheses, they found that both deforestation and afforestation had significant correlations to disease outbreaks. They found a strong association between deforestation and epidemics (such as malaria and Ebola) in tropical countries like Brazil, Peru, Bolivia, the Democratic Republic of Congo, Cameroon, Indonesia, Myanmar and Malaysia. In contrast, temperate regions like the USA, China and Europe showed clear links between afforestation activities and vector-borne diseases like Lyme disease.

Their approach did not distinguish between different types of reforestation activities, but they did find a significant increase in disease outbreaks in countries with expanding palm oil plantations. This was especially striking in regions of China and Thailand, where there was relatively little deforestation. These areas appeared particularly susceptible to mosquito-borne diseases like dengue, zika and yellow fever.

Amazon deforestation drives malaria transmission, and malaria burden reduces forest clearing | PNAS

Our work provides clear large-scale evidence that deforestation increases malaria, by using econometric techniques that approximate the gold standard of randomized controlled trials with observational data where controlled experiments are impossible. The effects of deforestation on malaria are largest in the early stages of deforestation in the interior of the Amazon as forest edge habitat increases, promoting mosquito vector breeding habitat, survival, and human biting rate (5615), but the effects attenuate as forest loss progresses, forest edge area declines, and human settlements become larger and further removed from forest (1021). The key implication is that forest clearing has a direct impact on human health, in addition to the loss of other ecosystem services such as species diversity, water quality, and carbon storage, that is quantifiable and predictable at regional and decadal scales.

Linking Deforestation to Malaria in the Amazon: Characterization of the Breeding Habitat of the Principal Malaria Vector, Anopheles darlingi

We postulate that deforestation in the Amazon changes the epidemiology of malaria by contributing to a change in Anopheles species composition and abundance, which results from the change in breeding site availability. In addition to changes in shade, vegetation, and hydrology resulting from deforestation, settlers often create artificial bodies of water such as fish farms and wells, and introduce new animal species.  The construction of roads through tropical rainforests also changes the surrounding ecology through erosion, blockage of streams, and by allowing previously inaccessible areas to become colonized by cattle ranchers, loggers, and farmers, thus exacerbating deforestation. , In this study, we examine the associations between A. darlingi larval presence and ecologic factors, in addition to studying the influence of landscape at larger scales.

Up to 5 Million Children Have Lost Parents During the Pandemic. How Children Who Became Orphans By COVID-19 Coped | Time (Me: In US – Stop denials and anti-vaxxing, get vaccinated!)

The cost of the COVID-19 pandemic is mostly noted in the people whose lives it has claimed—more than 740,000 in the U.S. alone, and more than 5 million worldwide. But there are the secondary victims, the collateral casualties—the spouses left widowed, the friends left bereft and, perhaps most poignantly, the children left orphaned. According to a survey recently published in Pediatrics—which relied on census data, as well as on publicly available figures on national fertility rates, deaths directly attributable to COVID-19 and excess deaths over the course of the pandemic compared to a similar period before the pandemic—the number of children in the U.S. who have lost at least one parent to COVID-19 now exceeds 120,000. The number who have lost a caregiving grandparent is greater than 22,000. And those figures take into consideration only the period from April 1, 2020 through June 30, 2021—missing the most recent summer surge entirely.

The Nationality & Borders Bill: Imperial nostalgia, fascist resurgence and social control – Media Diversified

Arguably the most ‘diverse’ cabinet in the history of UK politics has introduced possibly the most racist and regressive pieces of legislation this country has seen in decades. The Nationality and Borders Billshould force us all to rethink representation politics – if we have not already, and to accept many of the premises that sustain the quest for ‘equality’ are ill-conceived.

As part of this, recognising that we are all capable of reproducing racism within systems and indeed, that systems cannot function without the participation – passive or active – of those it harms, is crucial. We all need, and this may hurt even more, to come to terms with the fact, ‘diversity’, ‘equality’ and ‘inclusion’ will not save us. In fact, they are today more likely to do many of us harm, than to help us achieve any semblance of justice.

‘A Gut Punch’: Biden Interior Dept Quietly Plans to Strip Protections From Key Species (Me: Misleading headline… a department within Interior has made dumb recommendations but that does not equal “Biden Interior Dept”)

Writing to Interior Secretary Deb Haaland, Interior Department Inspector General Mark Lee Greenblatt, and other officials, the Center for Biological Diversity (CBD) demanded to know why the USFWS would decide now to reduce protections for species including the Florida panther, the Key deer, the Canada lynx, and the whooping crane.

In the case of the latter three, the group slammed the service’s proposal—buried in the regulatory agenda it released late last week—to downlist the species.
