Afghanistan and Nepal pledged $1 million each, the Maldives pledged $200,000 and Bhutan $100,000.
Bangladesh is also working on the making contribution to the fund, which will be finalised today, said a foreign ministry official.
The development comes amid rising cases of Covid-19 that has triggered lockdowns in many countries worldwide, especially in Europe. Experts warn that it may turn serious if immediate and effective measures are not taken now, especially in the countries that are highly populated.
Saarc leaders too voiced similar concerns during a videoconference on March 15. On that day, the Indian PM had made an initial offer of $10 million.
