Health and sanitation in shelters

There’s been at least 16 storms since the start of the year across Asia. Most recently a series of cyclones, monsoons and floods have killed more than 1,000 people in Indonesia, Sri Lanka and Thailand. Hundreds are still missing, hundreds of thousands are displaced, and several million are impacted. We speak with Lesthia Kertopati, senior journalist for BBC Indonesia about how days after the storm many on the Indonesian island of Sumatra are still desperately looking for their loved ones — and the challenges in the way of relief efforts.
