The gold method for detecting this virus is qRT-PCR, which is a semiquantitative technique where the viral load can be established through its cycle threshold (Ct). It has also been reported that COVID-19 generates long-term symptoms (post-COVID-19). Methods: After three months, a survey was performed on 70 COVID-19 confirmed patients; subsequently, we divided them into four groups (persistent symptoms, chemo-sensitive, cognitive issues, and changes in habit) in order to determine the correlation between viral load and post-COVID-19 symptoms. Results: Data show that fatigue, nervousness, anosmia, and diet changes are common long-term symptoms; in addition, a negative correlation was found between viral load and the number of post-COVID-19 symptoms. Conclusion: COVID-19 generates long-term symptoms which can cause problems with psychological and social repercussions.<\/jats:p>","DOI":"10.3390\/ijerph192215145","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T03:12:20Z","timestamp":1668654740000},"page":"15145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Post-COVID-19 Syndrome in Outpatients and Its Association with Viral Load"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3262-8279","authenticated-orcid":false,"given":"Daniel Alberto","family":"Gir\u00f3n P\u00e9rez","sequence":"first","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3864-5299","authenticated-orcid":false,"given":"Aimee","family":"Fonseca-Ag\u00fcero","sequence":"additional","affiliation":[{"name":"Laboratorio de Psicofisiolog\u00eda y Conducta, Unidad Acad\u00e9mica de Ciencias Sociales, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gladys Alejandra","family":"Toledo-Ibarra","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaqueline de Jesus","family":"Gomez-Valdivia","sequence":"additional","affiliation":[{"name":"Laboratorio de Psicofisiolog\u00eda y Conducta, Unidad Acad\u00e9mica de Ciencias Sociales, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9602-9881","authenticated-orcid":false,"given":"Karina Janice Guadaluope","family":"D\u00edaz-Resendiz","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6785-6688","authenticated-orcid":false,"given":"Alma Benitez","family":"Benitez-Trinidad","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco Fabian","family":"Razura-Carmona","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3087-6914","authenticated-orcid":false,"given":"Migdalia Sarahy","family":"Navidad-Murrieta","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5396-5357","authenticated-orcid":false,"given":"Carlos Eduardo","family":"Covantes-Rosales","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6808-6590","authenticated-orcid":false,"given":"Manuel Ivan","family":"Giron-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Investigaci\u00f3n Para la Inocuidad Alimentaria (LANIIA) Unidad Nayarit, Universidad Aut\u00f3noma de Nayarit, Tepic 63000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,17]]},"reference":[{"key":"ref_1","unstructured":"IMSS (2022, August 05).
