The
World Health Organization has said another 50 suspected cases are being
investigated - without naming any countries - and warned that more cases are
likely to be reported.
Monkeypox
is mostly found in West and Central Africa, but additional cases have been seen
in Europe and other parts of the world in recent years. Those cases are
typically linked to international travel or imported animals infected with the
pox, the CDC (Centers for Disease Control and Prevention) said.
Belgium
introduces quarantine for monkeypox cases.
Belgium has become the first country to introduce a compulsory 21-day quarantine for monkeypox patients after reporting four cases of the disease in the last week.
Belgian health authorities took the decision on Friday,
according to Belgian media. Monkeypox
contact cases are not required to self-isolate but should remain vigilant
particularly if they are in contact with vulnerable people.
Monkeypox is a disease in the same family as smallpox and
symptoms include a distinct bumpy rash, a fever, sore muscles, and a headache.
Monkeypox is less deadly than smallpox, with a mortality rate below 4 percent, but experts are
worried about the unusual spread of the disease beyond Africa where it usually
circulates.
What
are the initial symptoms of monkeypox?
There is an incubation
period of some seven to 14 days, the CDC said. Initial
symptoms are typically flu-like, such as fever, chills, exhaustion, headache
and muscle weakness, followed by swelling in the lymph nodes, which help the
body fight infection and disease.
"A feature that
distinguishes infection with monkeypox from that of smallpox is the development
of swollen lymph nodes," the CDC said.
Next comes a widespread
rash on the face and body, including inside the mouth and on the palms of the
hands and soles of the feet.
The painful, raised poxes
are pearly and fluid-filled, often surrounded by red circles. The lesions
finally scab over and resolve over a period of two to three weeks, the CDC
said.
"Treatment is
generally supportive as there are no specific drugs available. However, a
vaccine is available that can be given to prevent the development of
disease," Jimmy Whitworth, professor of international public health at the
London School of Hygiene & Tropical Medicine, said in a statement.
How
is monkeypox spread?
Close contact with an
infected individual is required for the spread of the monkeypox virus, experts
say.
Infection can develop
after exposure to "broken skin, mucous membranes, respiratory droplets,
infected body fluids or even contact with contaminated linen.
When
the lesions have healed, the scabs (which might carry the infectious virus) can
be shed as dust, which could be inhaled
Where
did monkeypox originate?
Monkeypox
got its name in 1958 when "two outbreaks of a pox-like disease occurred in
colonies of monkeys kept for research," the CDC said. However, the main disease carrier of
monkeypox is still unknown, although "African rodents are suspected to
play a part in transmission. The first known case of monkeypox in people was recorded
in 1970 in the Democratic Republic of Congo during a period of intensified
effort to eliminate smallpox.
After
40 years with no reported cases, monkeypox reemerged in Nigeria in 2017, the
CDC said. Since then, there have been more than 450 reported cases in Nigeria
and at least eight known exported cases internationally.
