Vaccines at least 18 months off, WHO says, as scientists work to determine if virus causes microcephaly and Guillain-Barré

theguardian.com - February 12, 2016

The World Health Organisation expects the suspected link between the Zika virus and two neurological disorders, microcephaly in babies and Guillain-Barré syndrome in adults, to be established within weeks, a senior official has said.

Marie-Paule Kieny, the WHO’s assistant director general, told a news briefing on Friday: “We have a few more weeks to be sure to demonstrate causality, but the link between Zika and Guillain-Barré is highly probable.”

She said it would take at least 18 months to start clinical trials of potential vaccines on humans, adding: “Two vaccine candidates seem to be more advanced: a DNA vaccine from the US National Institutes of Health; and an inactivated product from Bharat Biotech, in India.”

Argentine & Brazilian Doctors Suspect Mosquito Insecticide as Cause of Microcephaly

A report from the Argentine doctors’ organisation, Physicians in the Crop-Sprayed Towns,[1] challenges the theory that the Zika virus epidemic in Brazil is the cause of the increase in the birth defect microcephaly among newborns.  

The increase in this birth defect, in which the baby is born with an abnormally small head and often has brain damage, was quickly linked to the Zika virus by the Brazilian Ministry of Health. However, according to the Physicians in the Crop-Sprayed Towns, the Ministry failed to recognise that in the area where most sick people live, a chemical larvicide that produces malformations in mosquitoes was introduced into the drinking water supply in 2014. This poison, Pyriproxyfen, is used in a State-controlled programme aimed at eradicating disease-carrying mosquitoes. . . .

Study Finds Zika Virus in Fetal Brain, a Clue in Outbreak

New details about the possible effects of the Zika virus on the fetal brain emerged Wednesday as U.S. health officials say mosquito eradication here and abroad is key to protect pregnant women until they can develop a vaccine.

European researchers uncovered an extremely abnormal brain — not only a fraction of the proper size but lacking the usual crinkly neural folds — in a fetus whose mother suffered Zika symptoms at the end of the first trimester while she was living in Brazil. . . .

. . . Whether the mosquito-borne virus really causes microcephaly isn't yet proven, but Wednesday's report in The New England Journal of Medicine offers additional biologic clues.

"This fetus was really devastated," said Dr. Michael Greene of Massachusetts General Hospital who with colleagues from Harvard reviewed the findings in an accompanying editorial.

Japan: Fukushima Clean-Up May Take Up To 40 years, Plant's Operator Says

Cleaning up Japan's Fukushima Daiichi nuclear plant, which suffered catastrophic meltdowns after an earthquake and tsunami hit in 2011, may take up to 40 years.

The crippled nuclear reactor is now stable but the decommissioning process is making slow progress, says the plant's operator Tokyo Electric Power Co, better known as TEPCO. . . .

. . . The biggest obstacle to closing down the plant permanently is removing all the melted nuclear fuel debris from three reactors, Ono told reporters after a press tour of the plant this week.

But TEPCO says it is in the dark about the current state of the debris.

President Barack Obama will ask the U.S. Congress for more than $1.8 billion in emergency funds to fight Zika at home and abroad and pursue a vaccine, the White House said on Monday, but he added there is no reason to panic over the mosquito-borne virus.

Africa's Population Will Quadruple by 2100. What Does That Mean for its Cities?

New population figures paint a difficult picture for African cities. But there's more to the story than sheer numbers.

Numbers continue to stack up against the world’s poorest continent.

Global population levels are expected to increase from a current figure of 7.2 billion to nearly 11 billion by 2100, according to figures released . . . by the U.N. Previously, it was believed the world’s population would peak at around 9.5 billion. Nearly all of this new growth, meanwhile, will occur in Africa, which is expected to quadruple in size.

Thousands of Civilians Reported Fleeing as Battle for Aleppo, Syria, Intensifies

           

Fierce fighting in Aleppo forces thousands to flee

Innocent civilians 'running for their lives' - A sense of panic among those fleeing

cnn.com by - Nick Paton Walsh and Don Melvin - February 5, 2016

(CNN) The battle for the devastated city of Aleppo -- once Syria's commercial heart -- is intensifying, and video has surfaced appearing to show thousands of civilians streaming out of the city. . . .

. . . But the latest video appears to show a sense of panic among the thousands of people streaming out of the city, fleeing for their lives -- bound, most probably, for the Turkish border, 60 miles (97 kilometers) to the north.

. . . And from there, they will push onward, perhaps, to Europe, which is experiencing one of the most significant waves of migration in recent decades.

A United Nations official, citing U.N. estimates made for emergency relief planning, told CNN that 321,000 civilians are thought to be in a rebel-held area east of Aleppo.

Bharat Biotech Says Working on Two Possible Zika Vaccines

Indian biotechnology company Bharat Biotech said on Wednesday it was working on two possible vaccines to fight the Zika virus, which has been linked to birth defects in thousands of babies in Brazil.

The virus is spreading rapidly in the Americas, and WHO officials on Tuesday expressed concern that it could hit Africa and Asia as well. No vaccine has been developed so far.

One of the possible vaccines is "recombinant", which means it is created by genetic engineering, while the other was "inactivated", and will enter pre-clinical trials in animals in two weeks, Bharat Biotech managing director Krishna Ella told Reuters.

WHO Says on Watch for Spread of Zika Virus to Africa, Asia

Reuters - by Stephanie Nebehay - February 2, 2016

GENEVA, Feb 2 (Reuters) - The Zika virus linked to a microcephaly outbreak in Latin America could spread to Africa and Asia, and the World Health Organization will set up monitoring sites in the poorest countries with the highest birth rates, it said on Tuesday.

. . . ”Most important, we need to set up surveillance sites in low- and middle- income countries so that we can detect any change in the reporting patterns of microcephaly at an early stage," said Dr. Anthony Costello, WHO director for maternal, child and adolescent health.

A WHO global response unit "using all the lessons we've learned from the Ebola crisis" has been set up, he said. Some 20 to 30 'sentinel sites' for surveillance could be established worldwide, mainly in poor countries lacking robust health systems.
