The first infection was detected on April 7, 2020 presenting a clinical picture with mild symptoms, in May a second PCR was performed and the result was negative. After more than three months the patient presented severe symptoms of COVID- 19 and this was confirmed by PCR-RT on the 14th of 2020.<\/p>\n\n\n\n
After the studies carried out with the biological samples and after the viral genome sequencing process of the two samples that were positive by PCR-RT, it was determined that it is the same viral strain and that it presents variations in two nucleotides.<\/p>\n\n\n\n
These results do not allow us to conclude that it is a reinfection, since more scientific evidence is needed, nor can we rule out that it is a process of persistence of the virus in its host. This finding opens more questions as to whether after a first exposure to SARS-CoV-2 we can generate a long-lasting immune defense. .<\/p>","protected":false},"excerpt":{"rendered":"
The UEES in collaboration with the USFQ have sequenced so far 14 SARS-CoV-2 genomes from Guayaquil, of which two samples belong to the same patient and there was suspicion of a possible re-infection.<\/p>","protected":false},"author":1,"featured_media":6717,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[75],"tags":[77],"class_list":["post-6715","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-noticias","tag-covid-19"],"acf":[],"yoast_head":"\n
