Hantavirus risk in Dhaka

Hantavirus Prevention Guide for Dhaka What is Hantavirus Hantavirus is a serious viral infection spread primarily through contact with infected rodents, their droppings, urine, or saliva. In humans, it can cause hantavirus pulmonary syndrome, a severe respiratory illness with high fatality rates. The virus becomes airborne when dried rodent waste is disturbed, making inhalation a key transmission route. Dhaka Specific Risk Factors Dhaka scores 58/100 on hantavirus risk due to several local conditions. The city's dense population creates abundant food waste that supports large rodent populations. Many residential buildings have poor structural maintenance with gaps and holes allowing rodent entry. Informal waste management and open garbage accumulation near homes provide ideal rodent habitats. Seasonal flooding during monsoon drives rodents into human dwellings. Overcrowded living conditions in older neighborhoods with shared walls and inadequate sanitation increase exposure chances. Limited public awareness about rodent-borne diseases compounds these structural problems. Actionable Prevention Steps Seal all entry points. Inspect your home monthly for holes larger than a quarter inch. Use steel wool and caulk to fill gaps around pipes, vents, and foundation cracks. Rodents can squeeze through very small openings, so check thoroughly. Eliminate food sources. Store all food in sealed metal or thick plastic containers. Clean up crumbs and spills immediately. Keep garbage in bins with tight lids and dispose of waste daily. Remove outdoor food sources like pet food left overnight. Safe cleanup practices. Never sweep or vacuum rodent droppings directly. Wet contaminated areas with bleach solution first, let sit five minutes, then wipe with paper towels. Wear rubber gloves and a mask during cleanup. Dispose of waste in sealed bags. Reduce outdoor habitats. Clear clutter, stacked materials, and dense vegetation within three meters of your home. Keep firewood and storage items elevated off the ground. Maintain dry conditions since rodents need water sources. Seek medical attention immediately if you develop fever, muscle aches, or breathing difficulties after potential exposure. Early treatment significantly improves outcomes.
