Peak of COVID-19 cases in China: it is number one among respiratory infections

Covid-19 cases in China have reached a peak, surpassing influenza as the leading cause of respiratory infections among patients with symptoms. In July, the country, which originated the SARS-CoV-2 pandemic, recorded a surge in cases that placed the coronavirus back at the top of similar flu-like syndromes for the first time this year. According to Chinese media reports, during the week of July 13–19, the positivity rate for Covid tests among patients with respiratory symptoms hit 16.3%, a rise of 4.3 percentage points compared to the previous seven days. By the following week, from July 20, the rate climbed another 4 percentage points, reaching 20.3%. The positivity rate was higher in southern provinces than northern regions, with the age group most affected ranging from 15 to 59 years old. The Chinese Center for Disease Control and Prevention noted that most patients exhibited mild symptoms. Recent updates from the agency indicate that after weeks of increased activity, viral levels remain moderate. The circulating variant is identified as BA.1.8.1. The agency explained that Covid-19 has become a common respiratory illness, typically triggering one or two epidemic fluctuations annually. The current increase, according to officials, represents a normal periodic fluctuation, with intensity comparable to that observed in the preceding two years. Elderly individuals and those with pre-existing chronic conditions remain at greater risk of developing severe disease, though targeted and effective treatments are available. The Cdc further clarified that no variants of the virus have been detected that pose a significant public health threat. Overall, the sharp rise in infections has not led to pressure on healthcare services. The resurgence of Covid in China raises questions about its interpretation. Dr. Fabrizio Pregliasco, a virologist, remarked that it serves as another reminder that Sars-CoV-2 continues to circulate globally and can lead to new waves even during summer months. He emphasized that the situation described by Chinese health authorities does not suggest the emergence of a variant capable of significantly altering the epidemiological landscape, nor does it indicate an increase in disease severity. Instead, he pointed out that it demonstrates the virus’s ability to adapt and continue spreading within a population where immune protection tends to decrease over time. Therefore, he concluded, the moment is not for alarmism, but for vigilance.
