The death toll in Bangladesh from this year's monsoon flooding has risen to at least 500.
Health officials say the number of Bangladeshi flood victims suffering from diarrhea and other waterborne diseases is also increasing.
More than 53,000 people have contracted diarrhea in Bangladesh. Doctors at the country's main diarrhea hospital, the International Center for Diarrheal Disease Research, say they have been struggling to cope with the outbreak.
In India, the monsoon death toll is also rising. Indian police say flash floods in the country's north have killed at least four people and left at least 50 people missing.
Tuesday's floods caused landslides that washed away at least 14 houses.
More than 2,100 people people have died in India, Bangladesh and Nepal since the torrential monsoon rains began in mid-June, the vast majority in India.
Relief efforts have been hampered by insufficient supplies and washed out roads.
This year's monsoon season in South Asia has produced the worst flooding in 30 years.
