Red Lung Disease is the plague that wiped out most of Earth's population. It is highly contagious and deadly within forty-eight hours.
Red Lung begins with the onset of flu-like symptoms including fever, aching, nausea, coughing, and fatigue. These symptoms persist for several days and then begin to escalate. Within one week of exposure, necrosis sets into the lung tissue, causing lesions and open sores. This, in turn, results in bleeding into the lungs, causing difficulty breathing, and the bloody coughing that led to the name “red lung.” Once lesions in the lungs begin, they proceed rapidly, ultimately resulting in death, generally within forty-eight hours. Death is most often ascribed to asphyxia from fluid accumulation in the lungs.
Mortality and ContagionEdit
Red Lung is an airborne virus, spread through viral droplet nuclei transmission – minute samples of the virus are transferred when an infected person coughs or sneezes, spreading mucus-coated virus molecules. The comparatively slow progress of the early stages of the virus and the mundane nature of the initial symptoms allowed Red Lung to spread through the population before public health officials could institute policies to curtail travel or quarantine suspected carriers. By the time world governments realized a problem existed, Red Lung was already rampant and spreading throughout all of the industrialized nations.
Before the public health systems crumbled, Red Lung mortality rates were measured at greater than 70%, on par with the worst outbreaks of the Bubonic Plague. The rare cases of recovery conferred immunity on the survivors. This immunity was found to be passed down through genetic bloodlines. Unfortunately, the death rate far exceeded the birth rate, leading to a rapidly declining population.
