The cause of TRALI is currently not fully understood. 80–85% of cases are thought to be immune mediated. [5] [6] Antibodies directed toward human leukocyte antigens (HLA) or human neutrophil antigens (HNA) have been implicated, with transfused antibodies shown to bind antigens expressed on pulmonary endothelial cells to initiate acute inflammation in the lungs.
It is often confused with transfusion-related acute lung injury (TRALI), another transfusion reaction. The difference between TACO and TRALI is that TRALI only results in symptoms of respiratory distress while TACO can present with either signs of respiratory distress, peripheral leg swelling, or both.

Fever of at least 39 °C, OR a rise in temperature of at least 2 °C from pre-transfusion values AND/OR other symptoms or signs, including chills (), painful muscles (), or nausea that are severe enough that the transfusion is stopped AND requires immediate medical treatment, admission to hospital, or lengthens the duration of hospital admission.
The amount of fresh frozen plasma required to reverse disseminated intravascular coagulation associated with purpura fulminans may lead to complications of fluid overload and death, especially in neonates, [7] such as transfusion-related acute lung injury. Exposure to multiple plasma donors over time increases the cumulative risk for ...
Trematodiasis is a group of parasitic infections caused by different species of flukes, in humans mainly by digenean trematodes. [4] Symptoms can range from mild to severe depending on the species, number and location of trematodes in the infected organism. [1]
Fire ants also sting humans, Frye says, which can cause small pus-filled bumps on the skin, according to the Cleveland Clinic. Other symptoms: Ant bites are typically painful and itchy.
For diseases where there is no effective cure, such as Zika virus, West Nile fever and Dengue fever, vector control remains the only way to protect human populations. [citation needed] However, even for vector-borne diseases with effective treatments the high cost of treatment remains a huge barrier to large amounts of developing world populations.
