Italy: ‘Dangerous increase’ in SARS-CoV-2 concentrations in wastewater of >30%
‘The national trend of SARS-CoV-2 concentrations in wastewater showed a “dangerous increase” (>30%) in SARS-CoV-2 concentrations in the weeks 24 and 25, 2022′.
- As of week 25 of 2022 (26.06.2022), a total of 6.475 wastewater samples were collected throughout Italy in the framework of the SARS-CoV-2 environmental surveillance (EU Commission Recommendation 2021/472)
- 6451 wastewater samples were analysed for SARS-CoV-2, and 87.2% of them were positive.
- The national trend of SARS-CoV-2 concentrations in wastewater showed a “dangerous increase” (>30%) in SARS-CoV-2 concentrations in the weeks 24 and 25, 2022 (period 13.06.2022 – 26.06.2022), compared to the previous weeks.
- The same increasing trend was documented in most of the Regions/ Autonomous Provinces.
- The observed significant increase of SARS-CoV-2 loads suggests a rise in the number of individuals excreting SARS-CoV-2, which is in agreement with the current new growth of Covid-19 cases, possibly in relation to the spread of the Omicron sublineage BA.5.
