Welcome Back to LA, Disease-Spreading Mosquitoes!: LAist

“The invasive Aedes species, which is what we are seeing a lot of, can transmit Zika, yellow fever, chikungunya and dengue,”

If a visitor comes to LA with active zika, yellow fever, chikungunya or dengue and is bitten by a local LA Aedes, that mosquito can become ground zero for the spread of those diseases in LA! With modern air travel and global warming, it is inevitable that those diseases get a foothold in LA unless LA has a very active and aggressive vector control system.

Animal cases of yellow fever near Rio de Janeiro, Sao Paulo | CIDRAP Deforestation drives new outbreaks

So far, yellow fever is currently being transmitted by two types of mosquitoes on Brazil, the Haemagogus or Sabethes. If yellow fever is introduced to a major urban center, the virus could jump to the Aedes aegypti mosquito, making human transmission more likely.”There is no evidence of human cases of yellow fever virus infection transmitted by Aedes aegypti, the vector that could sustain urban transmission of yellow fever,” the WHO said in its update.

ECDC reports spike in yellow fever from South America travel | CIDRAP

The European Centre for Disease Prevention and Control (ECDC) released a risk assessment on yellow fever yesterday, noting a new case of travel-associated disease in a person from the Netherlands. This is the fourth case reported in Europeans who had recently traveled to South America in the past 8 months.The traveler had recently returned from Suriname, a former Dutch colony on the northwestern coast of South America. The patient had traveled to Suriname in February and March, and the case was reported to the National Institute for Public Health and the Environment (RIVM) in the Netherlands on Mar 9.The three other recent yellow fever cases in Europeans with a history of travel to South America include two French nationals who visited several endemic areas of Peru and a Danish citizen got sick in Bolivia after visiting yellow fever endemic areas in the Amazon basin.

WHO | Yellow fever – Brazil

As of 3 March 2017, yellow fever virus transmission continues to expand towards the Atlantic coast of Brazil in areas not deemed to be at risk for yellow fever transmission prior to the revised risk assessment, supported by the scientific and technical advisory group on geographical yellow fever risk mapping (GRYF), and published by WHO in the Disease Outbreak News of 27 January 2017, and on the WHO International Travel and Health website on 31 January 2017 and 14 February 2017.

Link between deforestation and ebola a lesson in habitat encroachment | Stuff.co.nz

“We wondered if it was just because people were there, but we tested [and] it was actually due to the fragmented forest with people present … as people start to encroach.”Fruit bat populations increase in fragmented forest conditions, while their contact with humans also increases.Deforestation is increasing in West Africa to provide land to grow cocoa and palm oil and in central Africa, where other ebola outbreaks have occurred, to meet demand for hardwoods.”It shows there’s different implications in how you encroach in the environment. We in very rich countries, what are we doing that’s encouraging deforestation and habitat encroachment?

Gates Foundation Project to Eliminate Malaria Focuses on Insecticides | News | PND-  “Being a billionaire and inciting greed and status seeking behavior of all who come close can ruin any serious effort to understand and control malaria.”

The two technologies could be “transformational,” said Dan Strickman, a senior program officer at the foundation. The next challenge, however, will be to identify the approaches that work best in combination with existing medical treatments so as to shrink the footprint of the disease over the next ten to fifteen years, Karl Malamud-Roam, manager of Rutgers University’s public health pesticides program, told the Seattle Times.

Finding out how human behavior facilitates the expansion of growth of malaria carrying mosquitoes would cost less but would show that industrial farming and deforestation are the chief facilitators of malaria’s continual comebacks.

California’s Mosquito Population Has Increased Tenfold, And We’re To Blame: SFist – But disuse of DDT is not the driver – ubanization is.

That is to say, as humans continue to reshape the state to fit our desires, we are creating the conditions for a mosquito population explosion. To make matters worse, the channel reports that species capable of carrying the West Nile virus and Zika do well in California’s human-made environment. And scientists expect it to only get worse.”Urbanization, driven by human population growth and movement, has been a major driver of environmental change during the last century and is projected to increase substantially in the future across the globe,” the study authors write. “Our results suggest that urbanization is likely to drive additional changes in mosquito communities, including the expansion of habitat for urban mosquitoes.”

Congress Finally Agrees To Budget $1.1 Billion To Fight Zika: Gothamist

Yesterday, members of Congress remembered they are obligated to, like, do stuff, when they narrowly avoided a government shutdown by agreeing to allocate $1.1 billion to fight Zika.Initially, the bill was held up thanks to language that would bar funds from Planned Parenthood, since any effort to boost women’s healthcare is akin to slaughtering schoolchildren on national television. (Note that the actual slaughter of schoolchildren fails to prompt any Congressional action.) But yesterday the Senate approved the bill by a vote of 72-26, and later in the day the House of Representatives approved it 342-85, narrowly averting a shutdown that would leave the government without money to operate Friday at midnight.President Obama, who requested $1.9 billion in Zika funding in February, is expected to sign the bill into law by tomorrow. Though an initial iteration of the legislation prohibited funds from going to Planned Parenthood, that language has since been removed. “Women’s health should never be treated like a political football,” Senator Patty Murray, D-Washington, told NPR. “I am glad that Republicans finally agreed to set aside the extreme provisions that would have specifically blocked Planned Parenthood health care providers from accessing critical funding.”
