Summary of Key Points
The latest surveillance data released by the Chinese Center for Disease Control and Prevention on August 6 indicate that during the 31st week of 2026 (July 27 – August 2), the novel coronavirus remains the primary pathogen causing respiratory infectious diseases in China. The positivity rate in outpatient and emergency services exceeded 20%, although the increase has slowed down. Other respiratory viruses, such as influenza, are at a low prevalence level. This outbreak of the novel coronavirus is part of a cyclical fluctuation following the classification of the disease as a Class B, Category B management category; its severity is comparable to that of the previous two years, with no unknown pathogens or high-risk variants identified. The risk of severe cases mainly affects the elderly and individuals with underlying health conditions. The CDC has also provided recommendations for personal protection.
1. Novel Coronavirus Positivity Rate Still Exceeds 20%, but the Increase Has Slowed Down
- Data Overview: Among influenza-like cases in outpatient and emergency settings, the positivity rate for the novel coronavirus was 22.3% (an increase of 1.9 percentage points from the previous week), while the positivity rate among hospitalized severe cases was 8.2% (a decrease of 1.3 percentage points).
- Key Points: The overall upward trend has slowed, and the disease is now at a "moderate prevalence level." The current dominant strain is the NB.1.8.1 variant. The positivity rate is significantly higher in southern provinces than in the north, with the highest rates among people aged 15–59 (a group with more social activities and a greater risk of exposure).
2. Other Respiratory Viruses: Influenza at Low Prevalence, with Most on the Decline
- Influenza: Ranked second, the positivity rate was 13.3% (a decrease of 0.9 percentage points from the previous week), indicating a "low prevalence level." The main strains are B(Victoria) and A(H3N2), with higher rates among people over the age of 4.
- Enteroviruses: Ranked third, the positivity rate was 4.1% (a decrease of 1.8 percentage points), with higher rates in children under the age of 14.
- Human Parainfluenza Virus: This virus accounted for the third-highest number of hospitalized cases, with a positivity rate of 5.5% (an increase of 1.3 percentage points from the previous week), and the highest rates were observed in infants and young children aged 0–4.
- Other Viruses: Positivity rates for rhinoviruses and parainfluenza viruses have been fluctuating downward, remaining at low levels overall.
3. This Outbreak is a Normal Cyclical Fluctuation; No Need for Excessive Worry
- Nature of the Outbreak: The CDC emphasizes that after the classification of the novel coronavirus as a Class B, Category B disease, there will be 1–2 outbreaks each year in China. This current outbreak is part of a cyclical pattern, with a severity similar to that of the previous two years.
- Severity of Cases: Most cases are mild, but severe cases mainly affect the elderly and those with chronic health conditions (such as hypertension and diabetes). However, existing treatments are effective.
- Risk Control: No unknown pathogens or variants posing a significant public health risk have been identified, and the outbreak has not had a noticeable impact on the overall medical system.
4. How to Protect Yourself? Remember These Four Points
- Wear Masks Scientifically: Wear masks in crowded places (such as subways and hospitals) or when you are showing symptoms to reduce the risk of transmission.
- Maintain Hygiene Habits: Wash your hands frequently, ventilate rooms regularly, and avoid touching your mouth, nose, and eyes with your hands.
- Lead a Healthy Lifestyle: Maintain a regular schedule, exercise moderately, and boost your immune system.
- Get Vaccinated: Especially for high-risk groups such as the elderly and those with underlying health conditions, getting vaccinated in a timely manner can reduce the risk of severe cases.
Overall, although the novel coronavirus outbreak is still ongoing, the situation is under control. There is no need for panic; simply follow basic preventive measures. Pay special attention to the health of the elderly and family members with underlying conditions, and seek medical attention promptly if symptoms appear.
