This is a disease that can cause mass shrimp deaths, in a short time and has a high level of infection. Due to the infrastructure conditions of the farming area not meeting technical requirements, some households when shrimp got sick did not report to the authorities to handle the disease but discharged the water directly into the outside environment, so the disease spread and spread quickly.

Currently, Dien Chau Veterinary Station has provided 1 ton of chlorine chemicals to communes where the disease has occurred. At the same time, it is recommended that farmers absolutely do not take more water from outside the common water supply system into the pond when the safe water source has not been determined. To limit the outbreak of disease, Dien Chau District People's Committee has developed a plan to disinfect the environment and handle shrimp diseases. Accordingly, the Department of Agriculture and the District Veterinary Station have focused their forces to directly direct the communes to spray chemicals to disinfect the water supply and drainage systems and on diseased ponds; mobilize people to use lime powder to disinfect the area around the pond to minimize economic losses for the people./.
