Very likely that either strain generates no immunities and a reinfection will kill you from organ failure.
What if the Cytokine storm is triggered when getting second infection with different strain. They are so close genetically it may confuse the immune system somehow. Kinda like throwing a monkey wrench into the works.
Yes from the little I read/heard about it, when the immune system ramps up high to kill it, a sometimes a cytokine storm can occur, creating mass inflammation. From there the organs are in trouble, mostly the lungs with this disease. Sounds lovely, doesn’t it? Ugh.
