Flu cases are on the rise earlier than usual this year
At this time of year, it's not unusual to hear a lot more sniffling and sneezing around us - whether at home, while working in the office or as you pick the kids up from school. As the weather turns colder and winter approaches, it's inevitable that more of us will find ourselves feeling ill.
Scientists have said “flu is back” after a hiatus during the coronavirus pandemic, with levels of flu in England already on the rise despite many flu seasons peaking in December and January. Rates are estimated to be highest among five to 14-year-olds, with 12% of laboratory samples from this age group testing positive, according to the latest flu report.
But, overall, levels of flu are still low, meaning it is too early to predict how big the wave of infections will be. With coronavirus variants still circulating, as well as the common cold, sometimes it can be hard to know what's causing your illness.The NHS explains the main symptoms of the flu, covid and the common cold, but some of them can overlap. Their website does state, however, that the main differences between cold and flu is how quickly the symptoms come on and their severity.
Cold symptoms appear gradually and mainly affect your nose and throat, while flu symptoms can come on within just a few hours and impact more than just your nose and throat. A cold can make you feel unwell, but you should still be able to carry on with your day-to-day activities, but the flu can make you feel exhausted and too poorly to carry on as usual.The symptoms are the same in adults and children. Sometimes symptoms last longer in children.

Timing and Trends for Municipal Wastewater, Lab-Confirmed Case, and Syndromic Case Surveillance of COVID-19 in Raleigh, North CarolinaObjectives. To compare 4 COVID-19 surveillance metrics in a major metropolitan area. Methods. We analyzed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in wastewater influent and primary solids in Raleigh, North Carolina, from April 10 through December 13, 2020. We compared wastewater results with lab-confirmed COVID-19 cases and syndromic COVID-like illness (CLI) cases to answer 3 questions: (1) Did they correlate? (2) What was the temporal alignment of the different surveillance systems? (3) Did periods of significant change (i.e., trends) align? Results. In the Raleigh sewershed, wastewater influent, wastewater primary solids, lab-confirmed cases, and CLI were strongly or moderately correlated. Trends in lab-confirmed cases and wastewater influent were observed earlier, followed by CLI and, lastly, wastewater primary solids. All 4 metrics showed sustained increases in COVID-19 in June, July, and November 2020 and sustained decreases in August and September 2020. Conclusions. In a major metropolitan area in 2020, the timing of and trends in municipal wastewater, lab-confirmed case, and syndromic case surveillance of COVID-19 were in general agreement. Public Health Implications. Our results provide evidence for investment in SARS-CoV-2 wastewater and CLI surveillance to complement information provided through lab-confirmed cases.
