With Increased Cases of Rhinovirus, Understanding Symptoms, Prevention, and When to Seek Medical Attention
According to the Chinese Center for Disease Control and Prevention (China CDC), recent weeks have seen an increase in cases of the common cold, with a rising positivity rate for rhinovirus among influenza-like illness (ILI) cases in outpatient and emergency departments. In some southern provinces, rhinovirus detection rates have even surpassed those of respiratory syncytial virus (RSV), making it second only to influenza virus as a leading cause of respiratory symptoms. So, what is rhinovirus? Are its symptoms similar to the flu? How can it be prevented? And when should you seek medical attention? Let’s take a closer look.
Understanding Rhinovirus: The Main Culprit Behind the Common Cold
Rhinovirus is not a new virus—it was first identified in 1956. Named for its preference for the nasal environment, it is a common respiratory pathogen.
There are over 170 known serotypes of rhinovirus, and it spreads relatively easily. Transmission occurs mainly through respiratory droplets (inhaling droplets from coughs or sneezes) and contact (touching contaminated surfaces and then the mouth or nose).
Symptom Profile: Upper Respiratory Symptoms Prominent, Systemic Symptoms Mild
The incubation period for rhinovirus infection is 1–3 days. People of all ages are susceptible, though detection rates are higher among school-aged children. Compared to influenza and RSV infections, rhinovirus is characterized by prominent upper respiratory symptoms—such as nasal congestion, runny nose, and sore throat—with generally mild systemic symptoms.
Adults often experience low-grade fever or no fever at all, along with mild coughing. Children are more likely to develop fever, and infants may refuse feeding due to nasal congestion. Some may also experience gastrointestinal symptoms like vomiting or diarrhea.
Recognizing Risks and Signs for Medical Attention
Most healthy individuals recover from rhinovirus infection within 7–10 days without medical intervention. However, special populations—including infants, the elderly, and those with weakened immune systems—should remain vigilant, as the virus can lead to lower respiratory tract infections or trigger acute exacerbations of asthma or chronic obstructive pulmonary disease (COPD).
Seek medical attention if symptoms include:
Fever lasting more than 3 days
Lethargy or unusual fatigue
Shortness of breath or chest tightness
Signs of dehydration in infants (e.g., reduced urine output, dry mouth)
Scientific Prevention and Care: Focus on Non-Pharmaceutical Measures
Currently, there are no specific antiviral drugs or vaccines for rhinovirus. Prevention relies primarily on non-pharmaceutical strategies:
1，Daily Prevention
Wash hands frequently with soap and running water for at least 20 seconds.
Ensure indoor spaces are well-ventilated.
Minimize close contact with symptomatic individuals.
Avoid sharing personal items.
Clean frequently touched surfaces daily with 75% alcohol or chlorine-based disinfectants (e.g., bleach). After wiping, allow the surface to air-dry for 3–5 minutes; no need to rinse with water.
Strengthen immunity: Eat plenty of fresh fruits and vegetables, maintain a regular sleep schedule, avoid staying up late, and engage in moderate exercise such as brisk walking or jogging three times a week.
2，Home Care for Symptoms
Get plenty of rest and stay well-hydrated.
Use saline nasal sprays or drops to relieve nasal congestion.
Maintain indoor humidity between 50% and 60%.
For low-grade fever, prioritize physical cooling methods (e.g., lukewarm sponge baths)
3，Precautions for Those Infected
Cover mouth and nose with a tissue when coughing or sneezing.
Dispose of used tissues promptly.
Eat separately from family members and wear a mask to reduce transmission.
Winter is a high-incidence season for respiratory infections. Rhinovirus is common but preventable and manageable. Remember the core care mantra: “Rest more, drink more water, ventilate often, and limit spread.” Practicing basic non-pharmaceutical precautions can effectively reduce the risk of infection. Even if infected, most people recover smoothly with proper care.
