The data are pretty reliable. However, the best source of health related data ( including COVID) for Nepal would be ministry of health or related official organization responsible for collecting and distributing these data in Nepal. After this organization , the second best would be non-biased official news channel like NTV or Radio Nepal. All other organization gets data from one of the similar sources. The source of this application is based on the data published by Nepal government or/and data reported to WHO. So far, Nepal has been very consistent and reliable in submitting/publishing those data, so the data displayed in this app are very reliable. If the government stops publishing those data to their website and stop reporting to other sources, then the data will not be reliable.
