North Korea is expected to convey to South Korea on Monday the details of its humanitarian provision of the H1N1 influenza treatment sent to the North by Seoul.

On December 18th, the South shipped to the North 500-thousand doses of Tamiflu, which Pyongyang says has been distributed nationwide.

When the aid was given to the North, South Korea asked that the details of the administration of the drug be provided within 30 days.

An official at Seoul's Unification Ministry says if the North's message is not delivered through the Panmunjeom border village by Monday, the government will discuss follow-up measures.
