Exam-focused facts from the 11 May 2026 current affairs briefing.

Key facts

The United States Centers for Disease Control and Prevention (CDC) has classified the hantavirus outbreak response as a Level 3 emergency activation.
The emergency response was triggered following international concerns linked to an outbreak on the MV Hondius cruise ship.
The outbreak involves the Andes strain of hantavirus, which is the only known variant capable of limited human-to-human transmission.
Hantavirus typically spreads through the inhalation of contaminated particles from infected rodent urine, saliva, or droppings.
Severe cases of the infection can lead to Hantavirus Pulmonary Syndrome (HPS), a potentially fatal respiratory illness that can cause respiratory failure and shock.
