🦠Key facts about Marburg virus disease (MVD)

Formerly known as Marburg haemorrhagic fever, is a severe, often fatal illness in humans.

The average MVD case fatality rate is around 50%. Case fatality rates have varied from 24% to 88% in past outbreaks. Early supportive care with rehydration, and symptomatic treatment improves survival.

There are currently no approved vaccines or antiviral treatments for MVD, but a range of vaccines and drug therapies are under development.

Rousettus aegyptiacus, a fruit bat of the Pteropodidae family, is considered the natural host of Marburg virus.

The Marburg virus is transmitted to people from fruit bats and spreads among humans through human-to-human transmission

Atelectasis on lung ultrasound

Atelectasis is a frequent finding in lung ultrasound and represents partial or complete collapse of alveolar units. Ultrasound offers a highly sensitive bedside method for identifying these changes, particularly in critically ill patients. Collapsed lung tissue typically appears as a hypoechoic, tissue-like structure with preserved or reduced vascular markings. Dynamic air bronchograms suggest an obstructive process, while static bronchograms often indicate resorptive or compressive atelectasis.

Lung ultrasound enables accurate differentiation between atelectasis and consolidation, improves clinical decision-making, and supports real-time monitoring of therapeutic responses such as recruitment maneuvers, physiotherapy, or adjustments in ventilation strategies. Mastery of these sonographic patterns is essential for optimizing respiratory care.
