The first half of 2026 has seen several infectious disease outbreaks. The most serious is a major Ebola epidemic in the Democratic Republic of the Congo (DRC), along with smaller outbreaks of hantavirus, diphtheria, and cholera in other regions.

2026年上半年出現了幾次傳染病爆發。最嚴重的是剛果民主共和國（DRC）的大規模伊波拉疫情，以及其他地區較小規模的漢坦病毒、白喉和霍亂爆發。

The Ebola outbreak in the DRC is caused by the Bundibugyo strain, which is rare and has no approved vaccines or specific treatments. As of June 13, there are 782 confirmed cases and 181 deaths, meaning the fatality rate is about 23%. The disease is mostly in the Ituri province, but it has spread to other areas and into Uganda. Efforts to stop the virus are difficult because of political instability, the movement of nearly one million displaced people, and miners working in remote areas. Furthermore, a funding shortage of $21.5 million and a low contact tracing rate of 56% have made the response less effective.

剛果民主共和國的伊波拉爆發是由 Bundibugyo 病毒株引起，該病毒罕見且目前沒有獲批准的疫苗或特定治療方法。截至 6 月 13 日，共有 782 例確診個案與 181 例死亡，意味著致死率約為 23%。疾病主要集中在 Ituri 省，但已蔓延至其他地區及烏干達。由於政局不穩、近一百萬名流離失所者的移動以及偏遠地區的礦工，使得阻止病毒的努力十分困難。此外，資金短缺 2,150 萬美元以及 56% 的低接觸者追蹤率，導致應對措施效果不佳。

At the same time, there have been global problems with public health communication. In the DRC, people distrusted medical institutions, which led to the destruction of clinics. Similarly, a hantavirus outbreak on cruise ships showed that the US CDC was not communicating quickly or clearly enough. In Australia, the response to diphtheria was slowed because marginalized communities did not receive enough information on how to prevent the disease. Consequently, these examples show that when authorities fail to engage communities transparently, misinformation spreads and makes medical treatments less successful.

與此同時，全球在公共衛生傳訊方面出現了問題。在剛果民主共和國，民眾不信任醫療機構，導致診所遭到破壞。同樣地，郵輪上的漢坦病毒爆發顯示出美國 CDC 的傳訊不夠迅速且不夠清晰。在澳洲，由於邊緣化社群未能獲得足夠的疾病預防資訊，導致應對白喉的速度減慢。因此，這些例子顯示當當局未能透明地與社群接觸時，錯誤資訊將會傳播，使醫療治療的成功率降低。

In the United States, the 2026 World Cup has required health officials to be extra alert. Although the CDC and WHO state that the risk of Ebola entering the US is low, the government has started airport screenings and travel limits. To prepare, the US is monitoring wastewater and using a new Health Security Operations Center. However, some experts argue that the US's ability to handle large crises has decreased because the CDC has fewer staff and the US has withdrawn from the WHO.

在美國，2026年世界盃要求衛生官員必須格外警覺。雖然 CDC 和 WHO 表示伊波拉進入美國的風險很低，但政府已開始實施機場篩檢和旅行限制。為了做好準備，美國正在監測廢水並使用一個新的健康安全運作中心。然而，部分專家認為美國處理大型危機的能力已下降，因為 CDC 的職員人數減少且美國已退出 WHO。

Global health security remains unstable due to the appearance of vaccine-resistant strains, lack of funding, and a loss of trust between the public and health authorities.

由於出現疫苗耐藥菌株、缺乏資金以及大眾與衛生部門之間失去信任，全球健康安全依然不穩定。
