This is the first of three days of official mourning in Myanmar.

More than two weeks after the cyclone struck, the country's leaders are gradually giving in to pressure and taking advantage of foreign aid.

But what the government is allowing is still a small amount compared to the enormous need.

In Myanmar today, government officials remained out of sight.

Instead, a single flag at half-staff in Yangon signaled three days of mourning.

But there are signs the victims' isolation is no longer absolute.

The United Nations has been allowed inside the country.

In some places, survivors are now getting vaccinations.

But foreign aid agencies estimate only 20-percent of those affected is really getting help.

"Our staff is not allowed into the worst areas," said a worker from Doctors without Borders.

"We're stuck."

The Secretary General will finally visit this week.

"I want to see the conditions under which relief teams are working, and I intend to do all I can to reinforce their efforts in coordination with Myanmar authorities," stated the General.

But even a personal visit by top U.S. Admiral Timothy Keating did not convince Myanmar to let U.S. helicopters carrying aid to land in the country.

The military government told the U.S. to stop asking.

But in the pictures that are still emerging, despite government efforts to shut out the press it appears help, in any form, is what the survivors still need the most.
