The first half of 2026 has been characterized by multiple infectious disease outbreaks, most notably a significant Ebola epidemic in the Democratic Republic of the Congo, alongside localized occurrences of hantavirus, diphtheria, and cholera.

2026年上半年的特點是出現多次傳染病爆發，其中最顯著的是剛果民主共和國爆發嚴重伊波拉疫情，同時在局部地區出現漢坦病毒、白喉及霍亂。

The current Ebola epidemic in the Democratic Republic of the Congo (DRC) is attributed to the Bundibugyo strain, a rare variant lacking approved vaccines or specific therapeutic interventions. As of June 13, official data indicate 782 confirmed cases and 181 deaths, with a case fatality rate of approximately 23%. The outbreak is primarily concentrated in the Ituri province, though transmission has extended to North Kivu, South Kivu, and across the border into Uganda. Containment efforts are severely impeded by a complex nexus of geopolitical instability, including the displacement of nearly one million individuals due to armed conflict and the high mobility of artisanal miners in remote regions. Furthermore, a reported funding deficit of $21.5 million and a contact tracing rate of only 56% have compromised the efficacy of the response.

目前剛果民主共和國 (DRC) 的伊波拉疫情歸因於 Bundibugyo 菌株，這是一種缺乏核准疫苗或特定治療干預的罕見變異株。截至6月13日，官方數據顯示有 782 例確診病例及 181 例死亡，病死率約為 23%。疫情主要集中在伊圖賴省，但傳播已擴展至北基伍省、南基伍省以及跨境進入烏干達。由於地緣政治不穩定的複雜因素，包括武裝衝突導致近百萬人流離失所，以及偏遠地區手工礦工的高流動性，使得圍堵工作受到嚴重阻礙。此外，據報導資金缺口達 2,150 萬美元，且接觸者追蹤率僅為 56%，損害了應對措施的成效。

Parallel to the biological challenges, systemic vulnerabilities in public health communication have been observed globally. In the DRC, distrust of medical institutions led to the destruction of treatment facilities and resistance to safe burial protocols. Similarly, the hantavirus outbreak on cruise ships highlighted a perceived decline in the visibility and communicative agility of the US Centers for Disease Control and Prevention (CDC). In Australia, the diphtheria response was hindered by an information vacuum regarding preventative measures within marginalized communities. These instances suggest that the absence of transparent, tailored, and proactive community engagement facilitates the proliferation of misinformation, thereby undermining clinical interventions.

除生物學挑戰外，全球範圍內公共衛生傳播的系統性脆弱性也顯現出來。在剛果民主共和國，對醫療機構的不信任導致治療設施被毀，並對安全葬禮方案產生抵制。同樣地，郵輪上的漢坦病毒爆發突顯出美國疾病控制與預防中心 (CDC) 在公眾視線中的存在感與溝通靈活性有所下降。在澳洲，由於邊緣化社群缺乏關於預防措施的資訊，使得白喉的應對工作受阻。這些案例顯示，缺乏透明、量身定制且主動的社區參與會促使錯誤資訊傳播，進而削弱臨床干預的效果。

In the United States, the 2026 World Cup has necessitated a heightened state of epidemiological vigilance. While the CDC, WHO, and Pan American Health Organization characterize the risk of Ebola importation as low, the US has implemented airport screenings and travel restrictions. Preparedness strategies include the utilization of wastewater monitoring and the establishment of the Health Security Operations Center at Georgetown University. However, some experts contend that substantial personnel reductions at the CDC and the US withdrawal from the WHO have diminished the institutional capacity to manage large-scale health crises effectively.

在美國，2026年世界盃使得流行病學監控進入高度戒備狀態。雖然 CDC、WHO 及泛美衛生組織將伊波拉輸入的風險定為低風險，但美國仍實施了機場篩檢與旅行限制。準備策略包括利用廢水監控以及在喬治敦大學成立衛生安全行動中心。然而，部分專家認為，CDC 大幅裁員以及美國退出 WHO，已削弱了其有效管理大規模衛生危機的機構能力。

Global health security remains precarious due to the emergence of vaccine-resistant strains, systemic funding gaps, and a pervasive erosion of trust between public health authorities and affected populations.

由於出現疫苗耐藥菌株、系統性資金缺口，以及公共衛生部門與受影響人群之間信任度普遍下降，全球衛生安全依然處於不穩定狀態。
