Portland，Oregon
A tiny chub （鲦鱼)has bounced back from near extinction(灭绝) ．The U.S. Fish and Wildlife Service (FWS)says populations of the Oregon chub are healthy enough to remove the 9-cm-long fish from its list of threatened and endangered wildlife．Last week’s announcement marks the first time an endangered fish has recovered enough to be delisted
After the 1940s, the chub populations dropped sharply from habitat damage by pollution and dams．When the fish was listed by FWS in 1993，only nine remained．Predation(捕食)by large-mouth bass and other non-native fishes was the largest threat to the remaining chub．

HANGZHOU, April 4 (Xinhua) —Another H7N9 bird flu case has been confirmed in east China's Zhejiang Province, the provincial health department said Thursday, bringing the country's total number of cases to 10.
The patient is a 64-year-old man from Huzhou City. He became ill on March 29 and was admitted to a hospital in Huzhou on March 31.
On Thursday, medical experts confirmed that he was infected with the H7N9 bird flu strain after the provincial center for disease control and prevention said late Wednesday that he tested positive for the virus.
An investigation has found that all 55 people who had close contact with the man have not showed any abnormal clinical symptoms, the department said.
So far, China has confirmed 10 H7N9 cases — four in Jiangsu Province, two in Shanghai Municipality, one in Anhui Province and three in Zhejiang. The two patients in Shanghai and one in Zhejiang have died.
Health authorities and hospitals in many Chinese provinces have been on high alert for H7N9 cases.
In Nanchang, capital of Jiangxi Province, which neighbors Zhejiang, five hospitals have been selected and ordered to be ready to treat H7N9 patients, though no cases have been reported there.
China's health authorities have promised transparency(透明) and cooperation to the World Health Organization (WHO) in regards to human infections of the new strain of bird flu.
On Wednesday afternoon, the National Health and Family Planning Commission distributed prevention and control plans and technique directives（指示）to health institutions nationwide. "So far, the sources of infection have not been clear, but based on past experiences and recent epidemiological (病理学的) studies, the sources could be poultry or the secretion and excrement from poultry," according to the plan.
The Chinese Center for Disease Control and Prevention said Wednesday that no human-to-human transmission of H7N9 has been discovered and no epidemiological connection between these cases has been found.

Two more cases of H7N9 bird flu virus have been detected in Zhejiang province, including a man who died last week, authorities said on Wednesday.
The Chinese Center for Disease Control and Prevention confirmed that a 38-year-old patient surnamed Hong from Hangzhou, the provincial capital, who died in hospital on March 27, had the virus.
Hong was infected on March 7 while working in neighboring Jiangsu province. He returned home on March 18, according to the Zhejiang health department.

On Sunday, two men in Shanghai died from H7N9. A woman in Anhui province and four men in Jiangsu province remain in criticalcondition, which makes a large number of people scared to death.
All patients had fevers and coughs in the early stages before developing pneumonia(肺炎) and breathing difficulties, China's health authorities said.
Experts say genetic analysis shows that the H7N9 virus can be treated with Tamiflu, an antiviral drug that may slow the spread of influenza（流感，家畜流行性感冒） in the body.
Wang Xianjun, head of the Shandong provincial center of disease control, said H7N9 is sensitive to neuraminidase-inhibiting medicine such as Tamiflu, Qilu Evening News reported on Wednesday.
