Monkeypox outbreak to lead to a new pandemic? WHO answers as cases rise

More than 300 suspected and confirmed cases of monkeypox have so far been recorded in May in around 23 countries, mostly in Europe.

New Delhi: Amid the rising number of monkeypox cases around the world, the World Health Organization (WHO) on Monday (May 30, 2022) said that it does not believe that the recent outbreak outside Africa will lead to a new pandemic. The global health body also said that it remains unclear if infected people who are not displaying symptoms can transmit the disease.

More than 300 suspected and confirmed cases of monkeypox - a usually mild illness that spreads through close contact and can cause flu-like symptoms and pus-filled skin lesions - have so far been recorded in May in around 23 countries, mostly in Europe.

Asked whether this monkeypox outbreak has the potential to grow into a pandemic, Rosamund Lewis, technical lead for monkeypox from the WHO Health Emergencies Programme said, "We don`t know but we don`t think so."

"At the moment, we are not concerned about a global pandemic," she was quoted as saying by Reuters.

Once monkeypox has been contracted, the duration of the rash emerging and scabs falling off is recognised as the infectious period, but there is limited information on whether there is any spread of the virus by people who are not symptomatic, WHO official added.

"We really don`t actually yet know whether there`s an asymptomatic transmission of monkeypox - the indications in the past have been that this is not a major feature - but this remains to be determined," she said.

The WHO, meanwhile, is considering whether the outbreak should be assessed as a "potential public health emergency of international concern" or PHEIC. Such a declaration, as was done for Covid-19 and Ebola, would help accelerate research and funding to contain the disease.

Monkeypox virus kills 9 in Congo; first death in Nigeria in 2022

Nine people have died of monkeypox in Congo in 2022 while Nigeria has recorded its first death from the disease this year, the countries' health authorities said.

Dr Aime Alongo, chief of the Sankuru health division in Congo, said Monday that 465 cases of the disease have been confirmed in the nation, making it one of the worst-hit in West and Central Africa, where the disease is endemic.

The persistence of the disease in Congo is due to the consumption of dead monkeys and rodents, Dr. Alongo said.

The Nigeria Centre for Disease Control and Prevention announced that in 2022 it has confirmed 21 out of 66 suspected cases of the disease, which is usually endemic in Nigeria and other parts of West and Central Africa.

"The death was reported in a 40-year-old patient who had underlying co-morbidity and was on immunosuppressive medications," the Nigeria CDC said.

Nigeria has not had an outbreak of monkeypox since September 2017 but it continues to report sporadic cases. At least 247 have been confirmed in 22 of its 36 states since then with 3.6% fatality rate, the disease control agency said.

What is monkeypox virus?

Monkeypox is a rare viral infection similar to human smallpox. It was first discovered in 1958 in monkeys kept for research and the first human case of monkeypox was reported in 1970. The disease occurs primarily in tropical rainforest areas of Central and West Africa.

The virus belongs to the family Poxviridae, which also includes the viruses causing smallpox and cowpox disease. 

What are symptoms of monkeypox disease?

Monkeypox typically presents itself with fever, rash, and swollen lymph nodes and may lead to a range of medical complications. The disease is usually self-limiting with the symptoms lasting from two to four weeks. Severe cases can also occur. In recent times, the case fatality ratio has reportedly been around 3-6 per cent but can be up to 10 per cent. There are no reported deaths in this current spread.

How does monkeypox virus spread?

Monkeypox is transmitted to humans through close contact with an infected person or animal, or with material contaminated with the virus. It reportedly is spread by rodents such as rats, mice, and squirrels.

The monkeypox disease is transmitted through lesions, body fluids, respiratory droplets, and contaminated materials such as bedding. 

Health officials have also noted that some of these infections may be transmitted through sexual contact. The WHO said it was also investigating many cases being of people identifying as gay or bisexual.

The virus, however, is said to be less contagious than smallpox and causes less severe illness.

How are monkeypox cases treated?

Vaccines used during the smallpox eradication program also provided protection against monkeypox. Newer vaccines have been developed of which one has been approved for prevention of the disease. An antiviral agent developed for the treatment of smallpox has also been licensed for the treatment of monkeypox, according to WHO.
