Why the Menace of Mosquitoes Will Only Get Worse

Climate change is altering the environment in ways that increase the potential for viruses like Zika.

nytimes.com - by Maryn McKenna - April 20, 2017

 . . . Climate change is turning abnormal weather into a common occurrence: Last year was the warmest year on record, the third in a row, and there were more heat waves, freezes and storms in the United States that caused $1 billion or more in damage just in 2016 than in the years 1980 to 1984 combined. Anything that improves conditions for mosquitoes tips the scales for the diseases they carry as well: the West Nile virus that flattened Dallas, the dengue that returned to Florida in 2009 after 63 years and the newest arrival, Zika, which gained a toehold in the United States last year and is expected to surge this summer . . .

The number of babies born in Puerto Rico with microcephaly and other birth defects caused by the Zika virus appears to be unexpectedly low — so low that experts are beginning to question whether the actual count is being significantly underreported by authorities on the island.

The world built more renewables for far less money last year, report UN and Bloomberg New Energy Finance.

Stunning drops in the cost of wind and solar energy have turned the global power market upside down . . .

 . . . Unsubsidized renewables have become the cheapest source of new power — by far — in more and more countries, according to a new report from the United Nations and Bloomberg New Energy Finance (BNEF).

In just one year, the cost of solar generation worldwide dropped on average 17 percent, the report found. The average costs for onshore wind dropped 18 percent last year, while those for offshore wind fell a whopping 28 percent.

Why People Have to Learn to Live with Wildfires

grist.org - by Bobby Magill - April 17, 2017

Communities across the Western U.S. and Canada may have to adapt to living with the ever-increasing threat of catastrophic wildfires as global warming heats up and dries out forests across the West, according to a University of Colorado study published Monday.

Residents living in neighborhoods adjacent to forests — known as “wildland-urban interface” zones — will have to accept that many wildfires may have to be allowed to burn and that building new homes in fire-prone forests should be discouraged, the study says.

Firefighters and policymakers will also have to adapt in new ways as catastrophic wildfires burn more land and destroy more homes than ever before.

There’s Another Mosquito Carrying Zika Virus

Zika Found in Common Backyard Asian Tiger Mosquito

nbcnews.com - by Maggie Fox - April 14, 2017

A common backyard mosquito can be infected with the Zika virus and it may pass the virus along in its eggs, researchers reported Friday.

The findings add to worries that the Asian tiger mosquito, scientifically known as Aedes albopictus, could help spread the virus as mosquito season hits temperate regions of the world.

The study, published in the Journal of Medical Entomology, doesn't prove that tiger mosquitoes can spread Zika, which causes severe birth defects. But it adds to evidence that they might.

New CRISPR Tool Can Detect Tiny Amounts of Viruses

The Cas13a enzyme causes collateral RNA damage that is the heart of a new diagnostic system, SHERLOCK, that can detect minute quantities of virus and much more.  Broad Institute

 . . . That’s the realm of SHERLOCK, a new diagnostic system that can detect attomolar levels of viruses in a sample and also distinguish Zika from its close relative, dengue. This exquisitely sensitive and specific tool promises to help detect diseases that other diagnostics miss, and it’s simple and cheap to use. Sexier still, it exploits a variation of CRISPR, the genome-editing method that has become the rage in biology.

A Socio-economic Impact Assessment of the Zika Virus in Latin America and the Caribbean: With a Focus on Brazil, Colombia and Suriname

undp.org - April 3, 2017

In early 2016, Zika was declared a Public Health Emergency of International Concern due to its association with a surge of birth defects. Zika has since spread throughout Latin America and the Caribbean, with local transmission also reported in parts of the USA, Asia and Africa. The nature of the neurological complications Zika can cause in humans, and the emergence of a condition in infants known as ‘congenital Zika syndrome’, have posed and continue to pose a significant challenge to health specialists, international organizations and governments alike.

The United Nations Development Programme (UNDP), in partnership with the International Federation of the Red Cross and Red Crescent Societies (IFRC), produced this assessment of the socio-economic impacts of Zika on countries, families and communities, and to examine institutional responses.

Sick of hearing about Zika already? Get used to it as more birth defects related to the virus are expected in 2017 in Florida and throughout the U.S.

This summer, there will be a full-court press by health officials against Zika.

“It’s not something to be taken lightly,” said Dr. Alina Alonso, head of the Palm Beach County Health Department, in an interview with The Palm Beach Post.

un.org

6 April 2017 – In addition to the impact on public health, the tangible impact of the Zika outbreak, such as on gross domestic product (GDP), could cost the Latin American and the Caribbean region as much as $18 billion between 2015 and 2017, a new United Nations report has revealed.

The report Socio-economic impact assessment of Zika virus in Latin America and the Caribbean, prepared by the UN Development Programme (UNDP) in partnership with the International Federation of Red Cross and Red Crescent Societies (IFRC), has a particular focus on Brazil, Colombia and Suriname – countries that first reported the outbreak in October-November 2015.
