Cyclone Roanu, hit the country on Saturday, forcing 500,000 people to flee their homes.
Torrential rains, floods and landslides triggered by the cyclone killed 25 people, left over 200 injured and damaged nearly 85,000 homes in southern coastal regions, after authorities had evacuated half a million individuals to temporary shelters.
Ram Kishan's the Regional Emergencies Manager for South Asia for Christian Aid and told Premier prayer is "much needed," he said the disaster has not received much coverage in the news.
He said: "About one million people were evacuated from the risk areas to the cyclone shelter and to public buildings, that's reduced immortality, and probably that's one of the reasons it doesn't get much media attention - but our point's that it's saving lives.
"There's a success to it, because it's saved lives, but I think other critical areas like livelihoods and others, aren't being paying enough attention."
Christian Aid is planning to release an initial £25,000 of emergency funds for families badly affected by Cyclone Roanu.
Christian Aid's Country Manager for Bangladesh, Shakeb Nabi, based in Dhaka, said: "Access to food, safe drinking water, health supplies and sanitation materials is limited in some villages.
"Water points have been ruined, ground water contaminated and agricultural land destroyed.
"Tens of thousands of poor families will have lost most of their assets: not just their houses, but also their food stores, seasonal crops and vital livestock such as cows, goats and ducks.
"Large numbers of fisher folk have seen their nets and boats lost or damaged."
The charity says that efforts to fight poverty in the low-lying country have become even more difficult due to the impacts of climate change - extreme temperatures, erratic rainfall, and an increasing number of floods, cyclones and droughts.
