A 12-year-old boy from Phuc Tho district in Hanoi was recently diagnosed with Japanese encephalitis, the first case reported in the city this year. The boy showed symptoms of high fever and headache on June 16, followed by a stiff neck and inability to walk the next day. His family took him to the National Children’s Hospital, where tests confirmed that he had the Japanese encephalitis virus in his cerebrospinal fluid. Despite having received four shots of the Japanese encephalitis vaccine, including one just a day before his symptoms appeared, the boy still contracted the disease.
Japanese encephalitis is a serious disease caused by the Japanese encephalitis virus, which is transmitted strongly by the Culex tritaeniorhynchus mosquito, active in Vietnam from March to July. This mosquito species is prevalent in delta and midland areas and is responsible for most cases of Japanese encephalitis in Vietnam. The disease mainly affects children, causing encephalitis and meningitis with high mortality rates and long-term consequences such as difficulty communicating and working.
Symptoms of Japanese encephalitis can be challenging to detect early as they are similar to other infections. However, as the disease progresses, symptoms such as high fever, nausea, vomiting, headache, and lethargy become more apparent. If left untreated, it can rapidly advance to seizures, coma and even death within a few days. It can also lead to long-term neurological complications that impair communication and work abilities.
Vaccination is currently the most effective way to prevent Japanese encephalitis. The Department of Preventive Medicine recommends a series of three basic doses starting after one year of age followed by booster shots every few years until individuals reach 15 years old. By following this vaccination schedule individuals can significantly reduce their risk of contracting this potentially life-threatening disease.
The Hanoi Department of Health has urged parents to take their children for regular checkups at hospitals during peak mosquito season (March-July) when there is an increased risk of transmission.
It’s important for everyone to be aware of these dangers so that we can take preventative measures to protect ourselves and our loved ones from this serious illness.
In conclusion, Japanse Encephalitis is a serious disease that requires immediate attention if suspected or if someone displays its symptoms such as high fever
