The swine-flu virus continued its gradual global march on Tuesday, prompting countries to strengthen efforts to stem its spread, while President Barack Obama asked Congress for $1.5 billion in supplementary spending to prepare for a possible swine-flu pandemic and installed the newly confirmed Secretary of Health and Human Services, Kathleen Sebelius, to help lead the fight against the disease. In the U.S., the caseload rose to 67 across five states — 45 of them in New York City, where health officials are investigating two new possible outbreaks at city schools — with more virus samples awaiting laboratory confirmation. New Zealand and Israel confirmed their first cases, while Canada, the U.K. and Spain saw small upticks in their swine-flu caseloads.

Several countries tightened border controls and discouraged travel to affected areas — Cuba suspended all flights to and from Mexico — but the World Health Organization kept the pandemic alert level at Phase 4, still two phases below a full pandemic. Outside Mexico, the apparent epicenter of the A/H1N1 virus, there have been no deaths confirmed from the flu and relatively few hospitalizations, and health officials continued to preach the need for a calm response. "What we see in the United States, or have been seeing so far, has been milder," said Richard Besser, the acting director for the Centers for Disease Control.

WHO spokesman Peter Cordingley singled out air travel as an easy way the virus could spread, noting that the WHO estimates that up to 500,000 people are on planes at any time.

Governments in Asia — with potent memories of previous flu outbreaks — were especially cautious. Singapore, Thailand, Japan, Indonesia and the Philippines dusted off thermal scanners used in the 2003 SARS crisis and were checking for signs of fever among passengers from North America. South Korea, India and Indonesia also announced screening.

In Malaysia, health workers in face masks took the temperatures of passengers as they arrived on a flight from Los Angeles. China said anyone experiencing flu-like symptoms within two weeks of arrival had to report to authorities. China, Russia and Ukraine were among countries banning imports of pork and pork products from Mexico and three U.S. states that have reported swine flu cases, while other countries, such as Indonesia, banned all pork imports.

The CDC says people cannot get the flu by eating pork or pork products. Germany's leading vacation tour operators were skipping stops in Mexico City as a precaution. The Hannover-based TUI said trips through May 4 to Mexico City were being suspended, including those operated by TUI itself and through companies 1-2 Fly, Airtours, Berge & Meer, Grebeco and L'tur. Japan's largest tour agency, JTB Corp., suspended tours to Mexico through June 30. Russian travel agencies said about a third of those planning to travel to Mexico in early May had already canceled.

What You Can Do to Stay Healthy

There are everyday actions people can take to stay healthy.

• Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
• Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
• Avoid touching your eyes, nose or mouth. Germs spread that way.

Try to avoid close contact with sick people.

• Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
• If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
