Over 100 children have died in Bihar’s Muzaffarpur district due to an outbreak of Acute Encephalitis Syndrome (AES). The matter has now reached the Supreme Court, which will hear a plea seeking directions to the Centre to urgently constitute a team of medical experts for the treatment of children who are suffering from AES.
Everything you need to know about Acute Encephalitis Syndrome (Chamki Fever)
Encephalitis is inflammation of the brain caused most commonly by viral infection, affecting the central nervous system and hampering the neurological functions. There are two types of encephalitis – primary and secondary.
Primary encephalitis occurs when a virus or other agent directly infects the brain while secondary encephalitis results from a weak immune system’s reaction to an infection elsewhere in the body.
It is a serious public health problem in the country, currently engulfing the states of Bihar and Jharkhand.
What are the symptoms of AES or chamki fever?
Mild cases of AES may cause no symptoms. Most mild flu-like symptoms such as headache, fever, aches in muscles or joints and fatigue or weakness
Severe cases of AES or chamki fever can be life threatening and may require immediate medical attention. Some severe symptoms include confusion, agitation or hallucinations, seizures, loss of sensation or paralysis, muscle weakness, speech and hearing difficulties, loss of consciousness.
It most commonly affects children and young adults and can lead to morbidity and mortality. They show symptoms like bulging in the skull, nausea and vomiting, body stiffness, poor feeding, irritability.
Causes of encephalitis or chamki fever
Encephalitis is most commonly caused by viral infection but it is also caused by several other factors such as herpes virus, enteroviruses, mosquito-borne viruses, tick-borne viruses, rabies virus and childhood infections
In India, the most common cause is the virus that causes Japanese encephalitis (JE), Health ministry attributes 5-35% of encephalitis cases to JE virus. It can also be caused by Nipah or Zika virus.
In Bihar, the Directorate of Health Services (DHS) has claimed that the JE virus had caused only two of the encephalitis cases this year.
The exact cause is yet to be identified in the latest Muzaffarpur outbreak. The cause of death in most this year has been attributed to hypoglycaemia (low blood sugar level).
