Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia.

By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death.

The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit

from human to human.

"In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO.

Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico.

The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency.

Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems.

Secondhand smoke isn’t just a health threat to people.It can also hurt dogs and cats,veterinarians say.
According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency.
“Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one,” says veterinarian (兽医专家) Carolynn MacAllister of Oklahoma State University.
“There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets,” MacAllister said.“Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds.”
Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year.
“Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens,” MacAllister said.“This results in more carcinogens (致癌物质) reaching the lungs.”
Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant.
To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said.
