HIGHLIGHTS: 1. The Association of Southeast Asian Nations (ASEAN) today announced that Myanmar had agreed to accept international aid agencies and medical workers from all ASEAN countries to help with the relief effort. The 10-member ASEAN group also said Myanmar should allow more international relief workers into stricken areas. The Foreign Minister of Singapore said that ASEAN ?will establish a mechanism so that aid from all over the world can flow into Myanmar". Indonesia?s Foreign Minister said that each ASEAN country would send a team of 30 medical personnel very soon, with unrestricted movement in the country.... 2. Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator John Holmes arrived in Myanmar on Sunday evening. Today (Monday) he was able to visit Labutta and Wakema townships in the Ayeyarwady delta and saw first hand the situation in this area. The ERC spent time speaking with the IASC Country Team, Cluster Leads and representatives of the Myanmar Red Cross Society and the IFRC to gain a clear picture of the progress and challenges in the response. Tomorrow (Tuesday) the ERC meets with the Government of Myanmar.... 3. The humanitarian community indicates that 500,000 people receive some form of international assistance. This is substantially less that the 2.4 million estimated to be affected of whom more than half (1.4 million) in severely affected areas requiring prioritised assistance. It is clear that the emergency phase is set to continue for some time. Some people are moving back to their places of origin where they will need humanitarian assistance as well as the necessary support to restart their livelihoods and farming.... 4. Heavy rains are continuing and the conditions for road transportation remain poor in delta areas.... 5. Local authorities in Labutta granted access to villages outside of the town that had previously been restricted, as well as to eight government distribution stations, for the delivery of food assistance.... 6. Health supplies continue to reach the key hospitals in the major centres, yet delivery of this assistance beyond the hospitals to the outlying communities remains a challenge. At least 50% of health structures are damaged or destroyed and restricted access continues to hamper the relief efforts.... 7. Reliable reports of severe watery diarrhoea continue to cause concern. It is important to note that the number of cases is still within the normal seasonal range. A reliable early warning system has been put in place by the Ministry of Health, UN, national and international NGOs in the affected areas. The water supply system has been compromised in many areas forcing people to collect water from ponds and rivers which seem to be widely contaminated. Every possible action to prepare for a potential outbreak is being taken as all risk factors are present. With the upcoming rainy season dengue fever is also expected, however the current situation poses a more serious outbreak. The Ministry of Health has begun preparing prevention activities with the support of the Health Cluster.... 8. Also of concern is the fragile situation of children in the cyclone-affected areas. Pre-cyclone statistics did indicate that about one-third of children under five there suffer from some form of malnutrition. While the food supply to the affected areas has improved over the past few days, clearly huge infusions of food assistance are urgently required. Children are among the most vulnerable in any disaster and with so many children already in a weakened state, lack of nutrition, water, sanitation and shelter, can be a lethal combination.... 9. The Government of Myanmar today declared three days of national mourning for the victims of Cyclone Nargis, beginning on Tuesday 20 May. State media today reported that over 50 billion Myanmar kyats (approximately USD 46.3 million) have been spent on relief works and rehabilitation tasks to date. 10. There has been no change in the official figures for dead and missing. 77,738 are reported dead and 55,917 missing.
