Recently, more and more countries have reported confirmed and suspected cases of m& # 111nkeypox. The World Health Organization also issued a circular recently to remind global health agencies to pay attention to the development of the epidemic.

May 20, by the global spread of monkeypox news, related concept stocks continued to strengthen.

In recent years, mankind seems to be facing an increasing onslaught of new viruses. First came the coronavirus and its various mutated strains, then childhood hepatitis of unknown cause, and then the very rare monkeypox.

M& # 111nkeypox is usually found in central and west Africa,But starting about two weeks ago, the virus suddenly began to show up at a higher-than-normal rate in Britain, Europe, North America and elsewhereAnd has led to a number of confirmed and suspected cases.

On May 7, a patient who had recently visited Nigeria was diagnosed with monkeypox in England, followed by a rash of new cases in London and the North-East of England. Meanwhile, a growing number of countries have reported monkeypox cases -- one each in the US, Italy, France, Sweden and Belgium, 14 in Portugal, seven in Spain and two in Canada.

Early symptoms of m& # 111nkeypox include fever, muscle pain, headache, chills, fatigue and swollen lymph nodes, and many people develop a rash one to five days after the onset of fever.

The rash, which can look like chicken pox or syphilis, changes and goes through different stages of change, eventually scab and shedding. A person is infectious until all the scab has fallen off and there is intact skin underneath, although the scab itself can contain infectious substances.

Symptoms of the disease are usually mild and go away on their own within a month. The World Health Organization says,Children are at higher risk than adults, but it can cause complications during pregnancy, including stillbirth and congenital m& # 111nkeypox, and the death rate can be between 1 and 10 percent

Monkeypox was first identified in 1958, according to the CENTERS for Disease Control and Prevention. The name "monkeypox" was derived from two outbreaks of a pox-like disease in groups of monkeys used in experiments, while the first recorded human case of monkeypox occurred in 1970 in the Democratic Republic of Congo, during an effort to eradicate smallpox.

Monkeypox reappeared in Nigeria in 2017 after a 40-year period of no reported cases, the agency said. Since then, the country has reported more than 450 cases and has at least eight exported cases internationally.

In 2003, there was an outbreak of monkeypox in the United States, with 47 confirmed and suspected cases reported in six states. All cases were contracted after contact with prairie dog pets, which in turn became infected when they were placed near small mammals imported from Ghana. This is the first human case of m& # 111nkeypox outside Africa.

Although it is suspected that African rodents are involved in the spread of monkeypox, the host of monkeypox remains uncertain.The virus does not spread easily from person to person, but can be spread through close contact with infected animals, people or contaminants such as towels and bedding, as well as contact with droplets, body fluids or monkey pox.

In addition, m& # 111nkeypox cases also occur in gay and bisexual men, or men who have sex with men. Although it is not known whether the virus can be transmitted sexually, some experts believe that is one way of transmission.

Some experts believe the current incidence of m& # 111nkeypox infections around the world indicates that the disease has spread in communities, but it is not clear whether there is cross-infection between different communities, how the link exists, or how long the disease has been circulating. Maria Van Kerkhove, head of the WHO's emerging diseases department, said, "It's clear... It's been going on for weeks."

It is worth noting that there are two strains of monkeypox, one endemic in West Africa and the other endemic in the Congo Basin. The former, which officials believe is linked to the current outbreak, has a fatality rate of about 1 percent, while the latter has a much higher fatality rate of 10 percent.

The CDC says there are no proven, safe treatments for m& # 111nkeypox approved for use in the US, but it says,The outbreak can be controlled by vaccination against smallpox, a virus closely related to monkeypox

Still, smallpox vaccine is limited and scarce because the virus was eradicated more than 40 years ago, meaning that few people under age 40 or 50 get vaccinated.

On Wednesday, the United States exercised a $119 million contract for vaccine company Bavarian Nordic to produce the only FDA-approved smallpox vaccine, which is also approved to fight monkeypox. However, those vaccines are expected to be produced in 2023 and 2024.

Dr. Vivek Murthy, Surgeon General of the United States, told CNN that people don't have to worry about the disease yet, since "the number of people who have gotten it is still very small." "We want people to get informed about the disease, and then go to their doctor if they are really concerned."

May 20, due to monkeypox short-term concept, A shares of diagnostic concept stocks strengthened. Among them, Zhijiang Biological (688317.SH) rose by the daily limit of 16.34 percent to 41.3 yuan. Daan Gene (002030.sZ), Wantai Biological (603392.SH), Changchun Gaoland (000661.sZ) and so on.

On the news page, The company said that it has a monkeypox virus nucleic acid assay kit (fluorescence PCR method), which specifically detects monkeypox virus nucleic acid fragments. The kit can be used for clinical or scientific diagnosis of diseases caused by monkeypox virus infection.

And daan gene said today in the investor interactive platform, the company has monkeypox virus related scientific research products reserve, but currently there is no relevant certified reagent.
