Please note, not all rigor criteria are appropriate for all manuscripts.
Table 1: Rigor
Ethics Field Sample Permit: Prior to the collection of samples, authorization for the entry of field personnel was coordinated with those responsible for markets, supermarkets, banking agencies and transport units in each district.

Experimental Models: Cell Lines Sentences Resources Vero-E6 cells were cultured in DMEM (Dulbecco’s Modified Eagles Medium) culture medium supplemented with streptomycin 100 mg/L, ampicillin 25 mg/L, 20% inactivated fetal bovine serum (SFB) and kept at 37 °C in a humid atmosphere of 5% CO2. Vero-E6suggested: NoneSoftware and Algorithms Sentences Resources Analysis of data: The information registered in data collection sheets, as well as the results of the molecular tests were entered into an Excel database. Excelsuggested: NoneThe analysis was carried out in the statistical program SPSS V25. SPSSsuggested: (SPSS, RRID:SCR_002865)Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).
Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The study also has limitations, such as that the collection of samples was carried out in the months of November and December, a period in which the number of new cases was less than 1,000 in Lima, Peru, according to the National Center for Epidemiology, Prevention and Control of Diseases. It is important to indicate that the World Health Organization mentions that the biological basis for the possibility of infection through contact with surfaces and food is related to fomites, which is still considered a concept with contradictory evidence (27). Furthermore, the study was carried out only in districts of Lima, Peru, and not in other regions of the country; however, it should be considered that these districts were the ones that showed the highest number of infections in the most critical period of the pandemic in Peru. Another limitation, is the lower isolation of virus from samples with higher Ct value, Ct > 31 by RT-PCR method. The rt-PCR Ct value correlate strongly with cultivable virus and likelihood of infectiosness, In this sense, a higher number of positive samples, will offer us the probability of a greater number of virus isolation (11). An additional aspect to consider is that, in the study period, frequent cleaning of the surfaces to be studied was observed, which could have had an impact triggering lower possibilities of obtaining positive results, but not on the elimination of their detection as has been described in previous experiences (23). Peru has been one...
