India, Oct. 4 -- Mounting concerns over waste disposal and poor hygiene in fast-growing parts of the city - from PG hostels and migrant-populated sectors - have prompted a fresh cleanliness drive by the Noida Authority, aimed at curbing the spread of vector-borne diseases such as dengue and malaria, officials said on Friday.

Officials said that garbage black spots, irregular street cleaning and unhygienic conditions around food stalls have been flagged as potential health hazards. PG accommodation owners - who cater to large numbers of students and working professionals - have been directed to maintain strict hygiene standards within their premises.

Street vendors, too, have been asked to ensure cleanliness around their stalls.
