Global infectious disease trends show rising influenza and COVID-19 cases

Global infectious disease trends show rising influenza cases in the Southern Hemisphere, particularly in New Zealand, alongside increases in Type A influenza across China, Southeast Asia, and India.

COVID-19 cases are rising in Hong Kong, Singapore, and India due to the PQ.16.1.1 Omicron subvariant. While this variant shows increased immune evasion, its pathogenicity remains unchanged. In Asia, dengue fever is spreading during the rainy season, with significant outbreaks reported in Malaysia, Cambodia, Bangladesh, and Sri Lanka.

Other notable outbreaks include: - Zika virus: The US CDC has issued a Level 2 alert for Bali, Indonesia, advising pregnant women to avoid travel. - Ebola: The Democratic Republic of the Congo is experiencing its largest outbreak on record, with over 5,290 cases and 2,516 deaths reported in six provinces. - Mosquito-borne diseases in Europe: Cases of Chikungunya, Dengue, and West Nile fever are increasing, particularly in Italy, Greece, and Spain.

In Japan, Aomori Prefecture has entered an influenza epidemic period, marking the earliest onset in the past decade.
