Sudden infant death syndrome(generally known as SIDS) leads to accidental death of infants under 12 months of age for unknown reasons. It was once called sudden death. It was a terrible event. This usually happens overnight, without any signs or evidence of inappropriate behavior leading to death. Men are more common than women and are more common among many non Europeans. This is the main reason for infant mortality in developed countries. Some studies show that infant mortality is increasing. The actual reason has not been determined. If an infant has potential physiological sensitivity and is at a critical growth age, it will encounter any external environmental trigger factors, and sudden infant death syndrome will occur. Some infants have multiple risk factors and may be more susceptible to SIDS. These risk factors include genetic predisposition, sleeping on the stomach, overheating, parents drinking, smoking contact, sleeping with father or mother, and being born before 39 weeks of pregnancy. In some cases, anemia can also be confirmed. In very few cases, if children are abused in the way of intentional asphyxiation, they are likely to be misdiagnosed as SIDS, which is why all conditions should be thoroughly examined.

Public health publicity has been carried out and will continue. It is speculated that these publicity will effectively reduce the incidence rate of sudden infant death syndrome by about 80%. Almost the most successful way to reduce the incidence rate of SIDS is to put infants less than 1 year old on their backs to sleep. In addition, there are many other strategies, such as a stronger mattress, sleeping in a different bed from the guardian, not using loose sheets, pacifying the nipple, a relatively cool sleeping environment and keeping away from cigarette smoke. In addition, breastfeeding and immunization are also preventive. Of course, there is good evidence to show that, although vaccination conspiracy theorists say that this is not the case, the possibility of children being affected by vaccination is not high at present. The use of baby protectors has not actually reduced this situation. In the news, infants usually appear in a sleep position that is not recommended, which may be criticized by the pediatric organization.

Help to young families with SIDS is very important for the treatment of grief, because the infant’s death is accidental and there is no alarm. In addition, the relevant forensic investigation can eliminate the suspicious factors in the infant death and bring great pressure to the family. The correct diagnosis of sudden infant death syndrome needs to be verified by autopsy, which may also be disconcerting. The tragic situation and many risks associated with small island developing States may be improved. Therefore, long-term community education and public health activities are needed to introduce new born parents, groups mainly increasing risks and vulnerable groups on how to minimize risk factors and how to provide services locally in the event of sudden death.
