Located in the Arctic Circle, Alaska is cold and dry, with fresh air, sparse population and rich biological resources. But it also means that many pathogens, especially those carried by wild animals, are rampant here. These pathogens can spread to the human body through air, food and contact, thus causing various diseases, including encephalitis.

At the same time, Alaska residents traditionally live on seals and venison, and the habit of eating raw meat and sashimi also increases the risk of encephalitis. After all, the germs and viruses in these wild animals are not so easy to be eliminated.

2. Winter is the high incidence season of encephalitis.

In Alaska, the epidemic of encephalitis mainly occurs in winter, which may be because the migration of wild animals in winter brings many potential pathogens. In addition, in Alaska, the days are short and the nights are long, and the temperature is low. In order to keep warm, people often burn fire indoors to keep warm, which is also easy to cause air pollution, which in turn leads to the spread of diseases.

On the other hand, Alaska in winter is a season of great population mobility. Because this season, tourism, hunting and other industries are very developed and the population mobility is strong, which also provides convenient conditions for the spread of infectious diseases.

3. Natural disasters have aggravated the epidemic of encephalitis.

Alaska is located in the Pacific earthquake zone, and natural disasters such as earthquakes, landslides and tsunamis often occur, which also brings great challenges to the prevention and treatment of encephalitis. For example, in 20 18, a major earthquake occurred in Alaska, which caused a large area of power failure and road interruption, which led to the lag of materials and information, and then caused some interference in the fight against encephalitis.

In addition, due to the remote geographical location of Alaska, there is also a certain gap in medical level, which also increases the possibility of encephalitis death.

4. Alaska strengthens the prevention and control of encephalitis.

In order to effectively deal with the occurrence of encephalitis, the Alaska government has taken various measures, including increasing medical care services, strengthening epidemic monitoring and early warning, improving medical facilities, and strengthening public publicity and education. In addition, the Alaska government is also cooperating with the federal government, the Canadian government and international organizations to deal with the threat of disease.

In short, although Alaska is facing a variety of encephalitis epidemic threats, the Alaska government and residents will certainly take effective prevention and control measures to resist the future epidemic threats.
