We also believe that long-term inflammation, as long-term low viremia from the SARS virus, could lead to cardiac long COVID.

我们还认为，长期炎，如同SARS病毒引起长期低水平病毒血一样，可能导致心脏长期新冠。

In primary viremia the virus infects a part of immune system in the liver and spleen, called the reticuloendothelial system, which is made of phagocytic cells.

第一次病毒血中，病毒入侵肝脾部分免疫系统，即由巨噬细胞组成网系统。

About two weeks after entering the body, the virus starts infecting immune cells themselves - specifically T cells - and that is considered the secondary viremia.

大概两周之后，病毒开始侵犯免疫细胞，特别是T细胞，这就是第二次病毒血。

The virus now causes primary infection called varicella or chickenpox, and it has two stages - primary viremia and secondary viremia.

这时候引起初次感染叫水痘，有第一次病毒血与第二次病毒血2个阶段。

Birds act as a reservoir for the virus, meaning the virus can replicate at high enough levels to cause significant viremia, or elevated viral blood counts, which allows for transmission to other uninfected mosquitoes.

鸟类是此病毒宿主，意味着病毒可在其体以较高水平复制，以至于导致病毒血，继而传播给其它未受感染蚊子。
