Dr. Asis Min of Doctors Without Borders/Medecins Sans Frontieres is working in the aid group's operations base in Bassein in the southwestern Irrawaddy delta region of Myanmar -- the area hit hardest by the cyclone.

As of May 13, the group reported that it had 200 staff members in Myanmar with plans for more to arrive. The teams are conducting medical consultations, distributing food, plastic sheeting and other items, and working to purify water and clean up areas where people have taken temporary shelter. The group also was able to fly in three planes carrying 110 metric tons of relief supplies to Yangon to reinforce the teams on the ground, the organization said.

Where in Myanmar are you?
I'm in the capital of Irrawaddy division, the worst-hit part of Myanmar. Between 95 percent and 100 percent of the houses have been destroyed. One location is in the extreme south western part of Myanmar, where there are a lot of very small islands and small villages on the islands. Many small villages have been completely deserted -- there are probably no survivors. Those villages are no longer habitable.

Are you able to get around, or is anything hampering your movements?
In some villages there are only five to 10 survivors, who have been transferred to other villages because they can no longer live in their own village. Many people are still unaccounted for. All the boats locally were stranded or destroyed by the cyclone so it is very difficult for us to move from the place where we arrived to the other islands. It's very, very complicated because you can bring people and goods to one part of the island, but inside the island there are many villages where there is no transport. We are carrying sacks of rice, medical kits, and plastic sheets (for building temporary shelters) to these villages on motorcycles, the only form of transport available.

What are the greatest needs that you've observed?
It's a catastrophe that there were no preventive measures taken. The casualties and the damage are very, very high. It's a big catastrophe. What's needed is a quick mobilization in terms of water supply and other sanitation work. In terms of food and shelter, we're going to scale up our distributions in the coming days. At the beginning our supply was limited, so we had to provide food only for two or three days. As a result, we have to go back again to those areas, while at the same time we are reaching new areas.

It's getting better, but I would not say that there is food for everybody, because we have not reached everybody yet. In one of our first intervention areas, there is no other organization working. There is a small amount of rice provided by the government. But I don't think everybody has food. For the time being we need more emergency response in terms of food distribution, shelter and health care. It's a complete abyss. Places are destroyed completely.

What are the health dangers?
Most of the water sources have been contaminated. We are working on decontaminating the existing wells, but our capacity is very limited because we have not been able to send any materials like big water-bladders with modern decontamination technology. We currently have no means for that type of thing in the field. If we cannot act quickly in water and sanitation, then there is a huge risk of disease outbreaks.

Are you having any trouble bringing additional supplies into the country?
So far we have been managing with the supplies we had inside the country. We had operations already running so we could mobilize materials, medicines and food from the existing program very quickly. We are procuring supplies locally, but I guess this will not be possible for much longer. We have authorization to land charters from abroad so this will solve a little bit our problem of availability of goods. But that will not solve the problem of reaching quickly the extremely remote places without any infrastructure.
