澳大利亚东部地区2026年花粉季已正式启动，花粉症患者的症状出现时间较以往明显提前。1卫星数据显示，东部州在冬末春初时期的植被生长强于去年同期，这导致了花粉浓度提前升高。1相比之下，西澳大利亚由于降雨不足，植被生长较少，该地区的花粉季可能面临延迟。1
草花粉是澳大利亚最常见的季节性致敏源，影响近四分之一的澳大利亚人口。1历史上，悉尼的花粉季通常从9月延续至12月，而墨尔本和堪培拉则从10月初开始，持续至12月。1澳大利亚研究人员开发了名为AirRater的实时花粉监测工具，用于追踪花粉浓度变化。1免疫疗法作为一种治疗选项可能需要3至5年才能见效，且不一定对所有患者有效。1
Australia's pollen season has commenced in 2026, with residents across the eastern states experiencing hay fever symptoms earlier than in previous years 1. Satellite data indicates that vegetation growth in eastern regions has been stronger than in the previous year, contributing to the early onset of symptoms 1. In contrast, Western Australia faces delayed pollen season conditions due to insufficient rainfall, which has resulted in reduced vegetation growth 1.
Grass pollen represents the most common allergen triggering seasonal hay fever in Australia, affecting approximately one-quarter of the population 1. Historically, pollen seasons in Melbourne and Canberra typically run from early October through December, while Sydney's season extends from September to December 1. For those seeking long-term relief, immunotherapy may offer a solution, though it can require three to five years to take effect and may not prove effective for all patients 1. Researchers in Australia have developed AirRater, a real-time pollen monitoring tool designed to help residents track allergen levels 1.
