So is the time at which the coronavirus infects a cell


Brazilian scientists have captured images of the exact moment in which the new coronavirus infects a cell, it was reported Wednesday, the Oswaldo Cruz foundation (Fiocruz) of Brazil, the largest medical research center of Latin america.

The photographs were taken with a transmission electron microscope during a study on viral replication of SARS-CoV-2, the virus that causes the Covid-19, and show in detail the process of contamination of a cell, as announced by the Fiocruz, in a press release.

To do this, researchers from Fiocruz, a body linked to the Ministry of Health of Brazil, infected lineage cells “Vero”, which are frequently used for in vitro assays and cell culture, with the novel coronavirus.

In one of the snapshots, we observe a series of dark spots, which are in fact viral particles of the pathogen, trying to infect the cytoplasm of the cell, inside which is the kernel, responsible for saving the genetic material of the same.


In a second image, the coronavirus starts the infection process, and finally, in another decision, already visualized the viral particles on the inside of the cell.

The record is unprecedented in Brazil and is part of a research studying how to play the new coronavirus. It is led by scientists of the Laboratory of Morphology and Morphogenesis Viral and the Laboratory of Respiratory Viruses and Measles.


Brazil is the Latin american country most affected by the pandemic of the new coronavirus with 706 deaths and 14 thousand 275 confirmed cases until this Wednesday.

According to the Ministry of Health, which predicts that the peak will arrive between April and may, the data show a case-fatality rate of the pathogen in the south american country of 4.9 percent.

The state of Sao Paulo, the richest and most populous of Brazil, with around 46 million inhabitants, is the region hit hardest when you post 371 deaths, and 5.682 infections.
