Inside the Trump Administration’s Decision to Leave the World Health Organization – (Blinds US to potential pandemics for humans and animals, as well as new flu developments)

The move could for the first time cut the U.S. government out of the development of the seasonal influenza vaccine for the Southern Hemisphere, a process coordinated by the WHO in partnership with the United States. And the withdrawal from the WHO could impede access to an eventual COVID-19 vaccine if it is created overseas, current and former officials said. Leaving the organization could also significantly blind the U.S. to health threats in remote foreign locales that, as the pandemic has shown, have the potential to make their way to the U.S. shores. Experts also fear the impact on major initiatives to combat infectious diseases, such as a WHO-led program that is on the cusp of eradicating polio. “To do this in the middle of a pandemic is breathtakingly dangerous,” said Nancy Cox, a former CDC virologist, who for 22 years led the agency’s WHO center on influenza surveillance and control. “So I worry a lot about what’s going to happen to so many of the programs at WHO that were strongly supported financially and through expertise and consultation with the U.S. I just think it could be really bad.”

Brazil’s fight against dengue: A race against time | Americas| North and South American news impacting on Europe | DW | 21.09.2019

The number of dengue virus infections in Brazil has gone up 600% in 2019. Our report from the state of Sergipe looks at why the fight against the illness and its carrier, the tiger mosquito, is so difficult.

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.

Texas reports first local Zika case of 2017 | CIDRAP- Drip, drip, drip – pandemic start?

Texas health officials today announced the state’s first probable local Zika infection of the year, which also appears to be the first local case reported in the United States for 2017.The patient is a Hildago County resident who had not traveled outside the area or had any other risk factors, the Texas Department of State Health Services (TSDHS) said in a press release. Hildago County, located in the Rio Grande Valley, is in far southern Texas on the border with Mexico.The virus was probably transmitted by a mosquito bite in South Texas some time in the last few months, and lab tests show that the person is no longer at risk of spreading Zika to mosquitoes.In April the TDSHS expanded its recommendations for testing pregnant women and people with Zika infections in six South Texas counties, which led to thousands of tests being conducted and to the identification of the newly identified case.

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.

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.”
