Brazil warns against pregnancy amid surge in ZIKV birth defects

States of Emergency have been declared in six  Brazilian states after a surge in the number of suspected microcephaly among the newborn linked to Zika virus (ZIKV).

In Pernambuco State, about 1,000 cases have been reported. In Rio de Janeiro, about 400 pregnant women are suspected of having Zika infection. About 3 dozen related infant deaths are being investigated. 

Brazilian health authorities are advising would-be parents not to get pregnant, especially in the country’s northeast. The advice follows research that have linked the potentially deadly virus Zika, a mosquito-borne infection, to newborn microcephaly—a neurological disorder that can result in a severe birth defect in which the brain fails to develop properly and the head is much smaller than normal.

Microcephaly can be caused by genetic factors, infections, or injuries. In recent years, there have been between 150 and 200 cases in Brazil per year. As of 30 November, more than 1,200 cases had been reported in 10 states, all of which have also reported Zika virus infections, says Ana Maria Bispo de Filippis, head of the flavivirus laboratory at the Oswaldo Cruz Institute in Rio de Janeiro, Brazil.”

However, the number of suspected infections have now doubled to more than 2,400  cases and spared to 20 Brazilian states (compared with 147 cases last year).

 

Storms kill at least a dozen, injure dozens more, leave trails of destruction across the U.S. South

Gov. Haslam approved the Tennessee Emergency Management Agency’s recommendation to go to a Level III State of Emergency, after storms moved across the state Wednesday night, killing at least two people.

Gov. Deal declared a state of emergency in Georgia for Fannin, Gilmer and Pickens counties through January.

“Following severe weather that resulted in flooding, damage to roads and properties and downed trees, the state is working to ensure the affected counties have access to the resources necessary for response efforts,” said Deal.

Gov. Bryant has declared a State of Emergency in seven Mississippi counties after storms pummeled the state late Wednesday..

Benton, Coahoma, Marshall, Panola, Quitman, Prentiss and Tippah counties have all reported damage,  at least six dead and more than 40 injuried.

  • Macon County North Carolina issued a state of emergency after the storm caused severe flooding across the area.
  • An unknown number of people were injured after the storm overturned planes at a local airport northwest of the state, said reports.

A large tornado, one of at least 3 dozens, landed in Mississippi and raked along a 240-km trail to Tennessee.

SPC received hundreds of severe weather reports including 39 tornadoes, as of posting. Tornadoes left trails of destruction across multiple states: Alabama, Mississippi, Arkansas, Tennessee, and Illinois.

 

Beijing air pollution worsens significantly

Air pollution index (AQI) in China hit a high of 592 on Friday and persisted at 562, as of posting.

[The EPA’s revised breakpoints for the upper end of the hazardous air pollution band, AQI of 401 – 500, is equivalent to PM2.5 concentration of 350.5 – 500 μgm−³ averaged over a 24-hour period.  —Editor]

There’s apparent confusion among officials concerning the severity and duration of the smog events, on the one hand, and the extent of willpower exercised by government to shoo away the potentially deadly pollution, on the other. The official news agency, Xinhua, wrote:

Even though Beijing has lifted the red alert for severe pollution, the capital city will remain in haze for a few more days. [How dare smog worsens “even though” the authorities have downgraded the pollution warning to the lowest level. Ed.]

The Beijing municipal heavy pollution emergency response headquarters issued a blue alert for heavy pollution in the city on Thursday afternoon, saying smog will hit central Beijing and southern suburbs on Thursday night. It called on residents in these areas to take protective measures.

“Red” represents the most severe warning level on China’s four-tier warning system,  followed by orange, yellow and blue.

In addition to Beijing, at least 50 other cities in northern and eastern China have issued air pollution alerts for potentially deadly smog this week.

Air Pollution Causes 200,000 Early US Deaths: Study

Posted by feww on August 29, 2013

Victims of air pollution typically die about a decade prematurely

Air pollution causes 200,000 early deaths in the U.S., according to a new MIT study, which also finds vehicle emissions as the biggest contributor to these premature deaths.

Researchers from MIT’s Laboratory for Aviation and the Environment have tracked ground-level emissions from multiple sources including vehicle tailpipes, industrial smokestacks, marine and rail operations, and commercial and residential heating throughout the United States, and found that the pollution causes about 200,000 early deaths each year.

Highlights from the report

  • Road transportation are the most significant contributor to air pollution, causing 53,000 premature deaths.
  • Power generation follows closely with 52,000 deaths
  • California air pollution commits about 21,000 people to early deaths annually,
  • The highest emissions-related mortality rate among 5,695 U.S. cities mapped was in Baltimore, where 130 out of every 100,000 residents likely die each year due to long-term exposure to air pollution.

“In the past five to 10 years, the evidence linking air-pollution exposure to risk of early death has really solidified and gained scientific and political traction,” says Steven Barrett, an assistant professor of aeronautics and astronautics at MIT. “There’s a realization that air pollution is a major problem in any city, and there’s a desire to do something about it.”

The researchers have published their results in the journal Atmospheric Environment.

Dangerous air pollution lingers in Beijing, as landslide kills 46 in SW China

Air quality indexes in Beijing were approaching 500 on Saturday, as monitoring stations in various parts of the Chinese capital warned the density of PM2.5 particulates had reached 700 micrograms per cubic meter.

An hour earlier, monitors at the U.S. Embassy in Beijing had recorded an off-the-chart air-quality reading of 728 and PM2.5 density of 845 micrograms per cubic meter, reports said.

  • The air quality is regarded as ‘safe’ when the index is at 50 or lower, but hazardous for indexes between 301 and 500, when outdoor physical activities should be avoided.
  • Beijing city government issued new rules last year under which all outdoor sports activities must cease and factories have to reduce production capacity when air-quality index exceeds 500.
  • “Several other cities, including Tianjin on the coast east of Beijing and southern China’s Wuhan city, also reported severe pollution over the last several days.” AP reported.
  • The authorities have blamed the the high concentration of air pollutants on dense fog and lack of wind.

Landslide in SW China’s Yunnan Province

The death toll from a landslide that buried a village in a mountainous region in southwest China’s Yunnan Province Friday climbed to 46, rescuers said.

  • “The landslide hit the Zhaojiagou area of Gaopo Village, Zhenxiong County around 8:20 a.m. Friday. Zhenxiong is some 550 km northeast of the provincial capital, Kunming.”
  • The victims included 27 adults and 19 children, according to the local authorities.
