On the evening of May 22, CNBC said on the official wechat official account that, as the national team of China's biomedicine, Sinopharm group CNBC had sealed up cowpox after eliminating smallpox A rare disease called monkeypox is spreading around the world from Europe and the United States, which has attracted much attention to smallpox vaccine.
According to the World Health Organization, as of May 21, 92 confirmed cases and 28 suspected cases of monkeypox had been reported to the World Health Organization from 12 non monkeypox endemic countries. With the expansion of monitoring scope, more monkeypox cases are expected to appear in the world. Health departments in many countries call on people to seek medical treatment in time after symptoms appear.
Chinese biology said that monkeypox is a disease caused by monkeypox virus, which can be shared by humans and animals. The virus is closely related to smallpox virus and is usually transmitted among monkeys in central and West Africa, but occasionally to humans. In 1958, scientists first found monkeypox virus in laboratory monkeys, and in 1970, the first human case of monkeypox infection was found in what is now the Democratic Republic of Congo.
What are the symptoms of monkeypox infection? It is reported that monkeypox virus can be transmitted from animals to people through close contact. Although it is not easy to spread from person to person, it may also be infected in close contact with patients. The incubation period (from exposure to onset) for human monkeypox infection is 5 to 21 days. The initial symptoms of monkeypox infection include fever, headache, muscle soreness, back pain, swollen lymph nodes and so on. Later, it can develop into a large-scale rash on the face and body. Most patients recover within a few weeks, but some patients have serious symptoms or even death.
How to prevent monkeypox? China biology said that because monkeypox virus and smallpox virus belong to the same virus family, the vaccine against smallpox virus also has protective effect on monkeypox virus. The effect of smallpox vaccine on monkeypox prevention is about 85%.
"At present, the treatment of monkeypox has not been safely verified, but to control the outbreak of monkeypox, smallpox vaccine, antiviral drugs and cowpox immunoglobulin can be used."
Smallpox was eliminated by mankind in 1977, and China eliminated smallpox 16 years earlier than the world. Smallpox virus has been eliminated. Is there any more cowpox? China biological said that as the national team of China's biomedicine, it had sealed up cowpox after the elimination of smallpox.
After the efforts of several generations of scientific researchers, there have been no cases of smallpox in China since the early 1960s, and the vaccination work continued until the end of the early 1980s. "Although the virus has been eliminated, the meritorious cowpox is safely sealed up for emergencies. If there is a war, call back and win!" China biology said.

Belgium introduced a 21 day isolation policy for those diagnosed with monkeypox
Belgian health authorities recently issued a policy requiring people infected with monkeypox to be isolated for 21 days; Close contacts do not need to be isolated, but their health needs to be closely monitored.
Belgium's "liberty" reported on the 22nd that in view of the long incubation period of monkeypox, the health care and Health Bureau decided to introduce the above policy after consultation with the risk assessment organization. If someone has a suspicious rash, they should go to the emergency department as soon as possible, according to the free newspaper. People suspected of infection and diagnosed should avoid close contact with others.
According to several media reports, the fourth case of monkeypox was confirmed in Belgium on the 22nd. Belgian health minister said on the 20th that monkeypox only poses a "low risk" to ordinary people at this stage.
According to the data of the World Health Organization on the 21st, since the 13th of this month, 92 confirmed cases and 28 suspected cases have been reported in 12 countries without monkeypox virus in the three regional offices of the World Health Organization, and there have been no deaths so far. The confirmed and suspected cases are mainly from the UK, Spain and Portugal, and the rest are distributed in Belgium, Canada and the United States. Who predicts that the global monkeypox cases may increase further.
David chark, a professor at the Australian National University, said this time was somewhat unusual because there was no link between most monkeypox cases, which meant that vigilance was needed around the world. However, different from the COVID-19, people have more knowledge about poxvirus and can quickly take measures to block the transmission.
Sanjaya sennarayak, an infectious disease scientist at the Australian National University, pointed out that smallpox vaccine can provide cross protection, but it is uncertain how immune people who were vaccinated against smallpox decades ago can be to monkeypox. Some antiviral drugs can be used to treat monkeypox. (Xinhua News Agency)
