An explosion struck the entrance to a kindergarten in eastern China on Thursday, police said. State media said there were casualties, and videos purportedly from the scene and posted on social media showed children and adults lying on the ground, some bleeding.

Police officials said they are investigating and had no word yet on injuries or deaths.

Police said the blast struck at 4:50 p.m. Thursday at the Chuangxin Kindergarten in the city of Fengxian in Jiangsu province.

China’s coal emissions responsible for ’quarter of a million premature deaths’

Emissions from coal plants in China were responsible for a quarter of a million premature deaths in 2011 and are damaging the health of hundreds of thousands of Chinese children, according to a new study.

The study by a US air pollution expert, commissioned by Greenpeace, comes as many areas in northern and eastern China have been experiencing hazardous levels of air pollution in recent weeks. [...]

The analysis traced the chemicals which are made airborne from burning coal and found a number of health damages were caused as a result. It estimates that coal burning in China was responsible for reducing the lives of 260,000 people in 2011. It also found that in the same year it led to 320,000 children and 61,000 adults suffering from asthma, 36,000 babies being born with low weight and was responsible for 340,000 hospital visits and 141 million days of sick leave.

Le manque de transparence des autorités saoudiennes lors du déclenchement de cas du nouveau virus de grippe aviaire à Hufuf pose potentiellement problème.

Virus’s Toll in Saudi Arabia Raises Fears of Faster Spread - WSJ.com

nternational public-health officials say they are as concerned about the coronavirus as they are about the new H7N9 avian flu virus that recently began sickening people in eastern China. The flu has hit more people—128 are known to have been infected as of May 2, including 26 who died—than the coronavirus.

But the coronavirus so far appears deadlier, with 30 cases including 18 deaths. And it may now be spreading from one person to another, international health officials say—unlike H7N9, which isn’t spreading widely between people. [...]

“They may have much more information but it surely hasn’t been forthcoming,” said Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, of the Saudi government. “The Saudis need to lay this out as completely as possible. We’ve all been concerned about the lack of transparency with regard to the Saudi investigation. It’s not just about an endemic problem within the country. It represents a global threat.”

Origin and diversity of novel avian influenza A H7N9 viruses causing human infection : phylogenetic, structural, and coalescent analyses : The Lancet

The phylogeny of the H7 gene sequences available showed three main independent lineages—ie, American, Oceanian, and Eurasian lineages. The novel H7N9 virus fell within the Eurasian lineage, and was genetically close to sequences isolated from ducks in Zhejiang Province in 2011 (Figure 1, Figure 2). The H7 phylogenetic tree also showed that varied H7 viruses were circulating in wild ducks along the east Asian flyway, which covers eastern China, South Korea, and Japan. Genetic exchange between wild birds and ducks has also been recorded (figure 2). The estimated time to most recent common ancestor of the novel H7N9 strains was roughly January, 2012 (mean Jan 4, 2012, 95% highest posterior density March 5, 2011—Oct 12, 2012).
