Can objects touched by COVID-19 patients transmit the virus?

Introduction
The novel coronavirus can spread by contaminating surfaces through respiratory droplets from infected individuals. Others may become infected if they touch these contaminated surfaces and then touch their mouth, nose, or eyes. The virus survives longer in moist, enclosed environments, increasing transmission risk. However, the virus has a limited survival time on dry surfaces and is sensitive to alcohol-based and chlorine-containing disinfectants. Wearing gloves and frequent handwashing can effectively reduce the risk of infection.

Under normal circumstances, objects touched by individuals infected with the novel coronavirus may transmit the virus, but the risk is relatively low if the environment is dry and timely disinfection is performed. If you have any concerns, it is recommended to seek medical advice in advance. The detailed analysis is as follows:

The novel coronavirus can contaminate object surfaces through respiratory droplets from infected patients. Others may become infected by touching these contaminated surfaces and then touching their mouth, nose, eyes, or other facial areas. Particularly in damp and enclosed environments, the virus survives longer, increasing the risk of transmission.

However, the virus has a limited survival time on dry surfaces and is sensitive to alcohol-based solutions and chlorine-containing disinfectants. Timely cleaning and disinfection of objects, along with protective measures such as wearing gloves and frequent handwashing, can effectively reduce the risk of infection.

In daily life, maintaining environmental cleanliness and regular disinfection is essential—especially frequently touched items should be wiped down regularly. After handling potentially contaminated objects, avoid touching your face and promptly wash your hands thoroughly with soap or handwash to ensure proper personal protection.

What virus causes novel coronavirus infection?
In general, novel coronavirus infection is caused by the novel coronavirus. It is important to practice personal protection in daily life, wear masks properly when going out, and avoid crowded places. Wash hands frequently, maintain indoor ventilation, and reduce the risk of virus transmission. Keep a regular作息 (routine), eat a balanced diet, and consume more foods rich in protein and vitamins.

Does receiving too many COVID-19 vaccines make one more likely to get hepatitis B?
The development and production of COVID-19 vaccines are based on antigens related to the SARS-CoV-2 virus. The vaccine components do not contain any substances related to the hepatitis B virus. Their mechanism of action is to stimulate the body to produce antibodies against the SARS-CoV-2 virus, and they cannot cause hepatitis B disease out of nowhere. The causative agent of hepatitis B is the hepatitis B virus, which spreads through blood, mother-to-child transmission, and sexual contact—none of which intersect in any way with the administration of COVID-19 vaccines.

Why Are People More Prone to Catching a Cold When Exposed to Spring Breezes?
Spring breezes can easily cause colds, typically due to large temperature fluctuations, dry air, rapid virus transmission, fluctuating immunity, and inadequate protection. Significant temperature changes: During the spring breeze season, there is a noticeable difference between day and night temperatures. After warming up during the day, people tend to remove clothing, but temperatures may suddenly drop at night or when exposed to wind. The body struggles to adapt quickly, leading to reduced defensive function of the respiratory mucosa, making it easier for viruses to invade and cause colds.

What acupoints are located on both sides of the navel?
The acupoints located on either side of the navel are known as Tianshu points. Situated in the abdomen at the level of the umbilicus, 2 cun lateral to the anterior midline, they belong to the Foot-Yangming Stomach Meridian and are commonly used in clinical practice for regulating gastrointestinal function. If persistent pain, abnormal soreness, distension, or accompanying symptoms such as nausea and vomiting occur upon pressing these points, medical evaluation should be sought promptly. The Tianshu point is the front-mu point of the large intestine, capable of regulating the transmission function of the large intestine.

What does "comprehensive nucleic acid testing" mean?
In general, a comprehensive nucleic acid test usually refers to whole-genome sequencing or a thorough nucleic acid test. During the testing process, wear a mask at all times, maintain a safe social distance, and avoid gathering in crowds. Wash your hands promptly with hand soap or regular soap before and after sample collection. Speak as little as possible during the procedure to minimize droplet transmission. After testing, get adequate rest and drink plenty of warm water.

Can a cold be transmitted to people nearby?
If a cold is caused by a virus (such as influenza virus or rhinovirus) and is in the early stage of illness (1–3 days when symptoms are apparent), it can easily spread to others through respiratory droplets or direct contact. When patients cough or sneeze, they release virus-containing droplets; others may become infected by inhaling these droplets or touching contaminated objects. The risk is particularly higher in enclosed environments.

Is a person still contagious after fever subsides due to a cold?
If a cold is caused by the influenza virus, or if symptoms such as persistent cough, sore throat, and runny nose remain after fever subsides—even if the fever has only been gone for less than 24 hours—there may still be infectivity. Influenza viruses are highly contagious and can persist for a long duration; even after the fever resolves, residual virus may remain in the body and spread via respiratory droplets. The persistence of symptoms also indicates that the virus has not been completely eliminated, meaning there remains a risk of transmission.

Will wearing a mask worsen a cold?
In general, wearing a mask when you have a cold does not worsen the condition; instead, it helps reduce virus transmission and protects the respiratory tract. However, attention should be paid to proper mask selection and correct usage. Wearing a mask during a cold is an essential protective measure—the key lies in choosing the right mask and wearing it properly. At the same time, drink plenty of warm water, ensure adequate rest, and promote recovery, thereby protecting both your own health and that of others.
