Meningococcal meningitis, pneumococcal septicemia, and dengue fever are all infectious diseases with high mortality rates and can leave lasting effects. These diseases make prevention a top priority, and Dr. Nguyen Le Nga, Medical Manager of VNVC Vaccination System, emphasized the importance of proactive prevention measures.

Meningococcal meningitis is a serious condition caused by meningococcal bacteria that can lead to inflammation of the membranes surrounding the brain and spinal cord. The disease can progress rapidly, with a high mortality rate if not treated promptly. Prevention methods include vaccination and practicing good hygiene to reduce the risk of transmission.

Dengue fever is transmitted by mosquitoes and can have severe consequences if not treated promptly. While a vaccine is not yet available in Vietnam, preventative measures like avoiding mosquito bites and sleeping under nets can help reduce the risk of infection.

Cholera is a disease transmitted through contaminated food or water, causing severe symptoms such as acute diarrhea and dehydration. Vaccination is available for prevention, along with measures like consuming clean water and hygienic food to avoid contracting the disease.

Pneumococcal sepsis, caused by pneumococcus, is a leading cause of pneumonia and meningitis. Vaccination is an effective way to prevent this disease, along with general respiratory disease prevention measures to reduce the risk of transmission.

In conclusion, staying informed about these infectious diseases and taking proactive steps towards prevention are crucial in reducing mortality rates and sequelae associated with these illnesses.
