Because of global warming, the world is facing the mosquito-borne disease crisis, which gets worse in undeveloped areas with poor living conditions and inadequate pest controls. For example: Zika virus. The virus is transmitted to people through mosquito bites, and may affect the health of women and newborns. Epidemic prevention is designed for toilets in undeveloped areas where vector breeding is most likely to occur. In addition to rapid urine testing and tracking disease outbreak, Epidemic prevention can also release natural insecticide made of neem extracts from strip surface dissolved in urine, to effectively prevent vector breeding, and improve living conditions for refugees. The remaining plant fiber after extraction is used as raw materials for test strip and package, to optimize resource utilization and achieve bio-recycling. Epidemic prevention is designed to provide the corresponding rapid test for different diseases to stop global outbreaks.
