As the world continues to grapple with the ongoing coronavirus pandemic, another virus has emerged, causing widespread panic in China. The norovirus, known for its extreme contagiousness, has prompted health officials in major cities like Beijing, outbreak-a-world-well-being-emergency-as-new-variant-raises-considerations/” title=”WHO Declares Mpox … a World Well being Emergency as New Variant Raises Considerations”>Shanghai, and Guangdong to issue urgent warnings. Unlike the coronavirus, there are currently no vaccines and special drugs
available to combat norovirus, according to multiple health officials.
On February 18, the official WeChat account of the “Shanghai Disease Control and Prevention” issued a prevention reminder, stating that March is still in the high incidence period for norovirus
and that the virus remains highly contagious.
The WeChat public account “Shanghai Huashan Infection,” run by Zhang Wenhong and his team, also posted an article on the same day, describing norovirus as a nightmare for epidemic prevention
. The article highlighted the virus’s extreme contagiousness and its ability to spread rapidly through schools, companies, and even cruise ships. The article stated that norovirus is extremely contagious and more ‘crawling’ than imagined because it does not have a vaccine. There is no special medicine and only rely on supportive treatment, but it can easily cause people from a school, a company, or even a cruise ship to be attacked collectively
.
The Beijing Municipal Center for Disease Control and Prevention released a message on February 19, reminding students how to prevent norovirus after the start of the new semester. The article emphasized that norovirus has strong infectiousness and rapid transmission ability, and is generally susceptible to the whole population. It also noted that the immune protection time after infection is short, it is the main pathogen that causes acute gastroenteritis and is often transmitted in crowded places such as collective units
.

Recently, cases of super-contagious norovirus have been reported in Guangdong Province. According to mainland media reports, a man in Guangdong recently said that his wife was infected with norovirus after going to the public toilet. Because I was queuing up in the women’s bathroom, I went into a pit that was not cleaned and I stayed inside without wearing a mask for a few minutes. After I came out, I started vomiting, vomiting and diarrhea, and my fellow travelers also started to have a fever a few hours later.

Doctors have warned that under normal circumstances, the water in the toilet bowl in public bathrooms may mainly include E. coli, dysenteritis, streptococcal, norovirus, etc. The main transmission method of these intestinal pathogenic bacteria is ‘fecal oral’ transmission. If your hands are exposed to these pathogenic bacteria and eat directly without paying attention to hand hygiene, it may cause fecal oral transmission
.
The Shenzhen Center for Disease Control and Prevention in Guangdong recently announced that from February 12 to 18, the risk level of norovirus infectious diarrhea in Shenzhen was adjusted from low to “medium.” Shenzhen CDC reminds: Childcare institutions, primary and secondary schools, nursing homes and other collective units should take preventive measures to prevent their spread and spread.
In addition to norovirus, the coronavirus epidemic continues to spread in mainland China, with hospitals in many places full of people and funeral homes full, but the CCP conceals the real epidemic and the number of deaths.
The “Overview of National Statutory Infectious Disease Epidemic in January 2025” released by the National Bureau of Disease Control and Prevention a week ago, in January 2025 (0:00 on January 1 to 24:00 on January 31), the whole country (excluding Hong Kong, Macao Special Administrative Region and Taiwan, the same below) reported a total of 3,382,111 statutory infectious diseases and 1,701 deaths.
Among them, 33,218 people were infected with the new crown and 4 people died, 2,870,849 people were infected with the flu and 9 people died. H7N9 avian influenza and human infection with highly pathogenic avian influenza did not occur or die.
However, according to the situation reported by people in many places, the real death toll is estimated to be far higher than the official data released. People in Henan, Anhui and Fujian recently told New Tang Dynasty that many middle-aged and elderly people in the area have died, and the mountainous areas have almost become no-man’s land. Because there are too many people who have died, some areas have relaxed burials.
With the ongoing outbreaks of both norovirus and coronavirus, health officials in the U.S. are taking note. The Centers for Disease Control and Prevention (CDC) has issued guidelines for preventing the spread of norovirus, emphasizing the importance of hand hygiene, thorough cleaning and disinfection of surfaces, and proper food handling practices. In the U.S., norovirus is a common cause of foodborne illness, with outbreaks often occurring in settings such as cruise ships, schools, and nursing homes.
In response to the growing concern, the CDC has also launched a public awareness campaign to educate the public about the symptoms of norovirus and the steps they can take to protect themselves and their communities. The campaign includes educational materials, social media posts, and partnerships with local health departments to ensure that accurate information is disseminated widely.
As the world continues to navigate the complexities of infectious disease outbreaks, the norovirus situation in China serves as a stark reminder of the importance of vigilance and preparedness. While the U.S. has robust public health infrastructure and resources, the rapid spread of norovirus highlights the need for continuous education and preventive measures. By staying informed and taking proactive steps, individuals and communities can help mitigate the impact of such outbreaks and protect public health.
