Tracking SARS-CoV-2 in Sewage: Evidence of Changes in Virus Variant Predominance during COVID-19 Pandemic.

ABSTRACT: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), responsible for the ongoing coronavirus disease (COVID-19) pandemic, is frequently shed in faeces during infection, and viral RNA has recently been detected in sewage in some countries. We have investigated the presence of SARS-CoV-2 RNA in wastewater samples from South-East England between 14th January and 12th May 2020. A novel nested RT-PCR approach targeting five different regions of the viral genome improved the sensitivity of RT-qPCR assays and generated nucleotide sequences at sites with known sequence polymorphisms among SARS-CoV-2 isolates. We were able to detect co-circulating virus variants, some specifically prevalent in England, and to identify changes in viral RNA sequences with time consistent with the recently reported increasing global dominance of Spike protein G614 pandemic variant. Low levels of viral RNA were detected in a sample from 11th February, 3 days before the first case was reported in the sewage plant catchment area. SARS-CoV-2 RNA concentration increased in March and April, and a sharp reduction was observed in May, showing the effects of lockdown measures. We conclude that viral RNA sequences found in sewage closely resemble those from clinical samples and that environmental surveillance can be used to monitor SARS-CoV-2 transmission, tracing virus variants and detecting virus importations.

Project description:BackgroundSpeculation on benefits and harms of prescription, over-the-counter and complementary medications has been widespread during the SARS-CoV-2 (or COVID-19) pandemic. This community-based survey assessed self-reported changes in medications including those stopped, started, or if access had been impacted.MethodsA survey was collected via Research Electronic Data Capture (REDCap). The survey was advertised in the community through social media, email lists, websites, and post-cards. Survey responses were collected between 5/21/2020 and 6/24/2020. Variables included demographic characteristics such as age, sex, race, marital status, education, employment, income, and community type. Questions related to medication changes included: "Have you started any medication due to COVID-19?", "Have you stopped any medication due to COVID-19?" and "Have you had issues getting your prescription medications?". Respondents aged 50 years or older were included.ResultsThere were N = 1397 responses of which 1169 were older adults ≥50 years-old. Of these, 1141 responded to the medication changes survey questions and 28 had missing responses and were excluded from the survey sample for this analysis. Among these, 31 (2.7%) reported a medication change included 5 (0.4%) reported stopping a medication, 18 (1.6%) reported starting a medication, and 8 (0.7%) reported trouble obtaining medications. Medications started included mostly vitamins or other supplements including zinc (n = 9), vitamin C (6), and other supplements (3). Among prescription medications, antidepressants and anti-anxiety medications (4) were reported as well as aspirin (1), losartan (1), and low dose naltrexone (1). One respondent reported unidentified homeopathy. There were no significant differences between those with medication changes and those with none.ConclusionsIn this community-based survey sample of over one thousand older adults, only a small percentage (2.7%; n = 31) reported any changes to medications during the pandemic. As essential workers during this crisis, pharmacists have played a critical role in providing medication information and continued access.
