Pacheco's disease Pacheco's disease Pacheco's disease is an acute and often lethal infectious disease in psittacine birds. The disease is caused by a species of herpesvirus, Psittacid alphaherpesvirus 1 (PsHV-1), which consists of four genotypes. Birds which do not succumb to Pacheco's disease after infection with the virus become asymptomatic carriers that act as reservoirs of the infection. These persistently infected birds, often Macaws, Amazon parrots and some species of conures, shed the virus in feces and in respiratory and oral secretions. Outbreaks can occur when stress causes healthy birds who carry the virus to shed it. Birds generally become infected after
Refugee health had a 3% prevalence of hypertension, and nearly 1% prevalence of chronic obstructive pulmonary disorder. Tuberculosis (TB) is a bacterial infection that mainly affects the lungs. As an airborne disease, TB is spread via inhalation of the bacteria, which subsequently travel to the lungs and other body parts to manifest infection. Once a person is infected, TB can either become latent or active. If latent, the disease is asymptomatic and non-contagious; however, latent TB can become active at any point. Active TB is symptomatic and contagious. Either way, TB should be treated immediately, as untreated infections can be fatal. An
