Monkeypox
What is Monkeypox ?
Monkeypox is a viral zoonotic disease caused by the monkeypox virus, which belongs to the Orthopoxvirus genus. It is similar to smallpox but generally less severe. The disease was first discovered in 1958 in monkeys kept for research, hence the name “monkeypox.” It primarily occurs in tropical rainforest areas of Central and West Africa but has seen outbreaks in other parts of the world.
Monkeypox can spread to humans through close contact with an infected animal, person, or contaminated materials. It presents with symptoms similar to smallpox, such as fever, rash, and swollen lymph nodes, but is less contagious and often less severe. The virus enters the body through broken skin, respiratory tract, or mucous membranes, including the eyes, nose, or mouth.
Monkeypox Q&A
A: Symptoms of monkeypox include fever, intense headache, swelling of the lymph nodes, back pain, muscle aches, and a profound lack of energy. After 1 to 3 days, a rash typically appears, beginning on the face and spreading to other parts of the body. The rash progresses through different stages before finally forming scabs, which later fall off.
A: Monkeypox is caused by the monkeypox virus, a member of the Orthopoxvirus genus. It can spread to humans through direct contact with the blood, bodily fluids, or cutaneous or mucosal lesions of infected animals. It can also spread from human to human through respiratory droplets, contact with body fluids, monkeypox sores, or contaminated materials like bedding.
A: Monkeypox is diagnosed through a combination of clinical evaluation and laboratory tests. A healthcare provider will assess the patient’s symptoms, and a laboratory test, such as polymerase chain reaction (PCR), is used to confirm the presence of the monkeypox virus from a sample taken from the skin lesions.
A: There is no specific treatment for monkeypox, but the disease is usually self-limiting. Patients are typically advised to rest, stay hydrated, and manage symptoms. In severe cases, antiviral medications like tecovirimat may be used. Vaccination with the smallpox vaccine has also been shown to provide some protection against monkeypox.
A: Prevention of monkeypox involves avoiding contact with animals that could harbor the virus, particularly in regions where monkeypox is endemic. Personal protective measures, such as wearing gloves and other protective clothing when handling potentially infected animals, are recommended. In the event of an outbreak, vaccination and isolation of affected individuals are crucial to controlling the spread of the virus.
A: Yes, vaccines used for smallpox, such as the JYNNEOS (Imvamune or Imvanex) vaccine, can also protect against monkeypox. Vaccination is recommended for people who have been exposed to the virus or are at high risk of exposure.
A: If someone suspects they have monkeypox, they should seek medical attention immediately. They should inform their healthcare provider about their symptoms and any recent travel history or contact with animals. To prevent the spread of the virus, they should isolate themselves from others, cover any lesions, and wear a mask.

No need to panic
Mpox (formerly known as monkeypox) is an infectious viral disease affecting humans and other animals.
Mpox is caused by a DNA Virus unlike COVID virus which is a RNA virus (it’s important to know because RNA virus undergo rapid mutations)
Symptoms: Symptoms include a rash -> blisters -> crusts over, *fever, and *swollen lymph nodes. Exhaustion, muscle aches, sore throat.
Some people, the first symptom of mpox is a rash, while others may have fever, muscle aches or sore throat first.
The mpox rash often begins on the face and spreads over the body, extending to the palms of the hands and soles of the feet.
{It can also start on other parts of the body where contact was made, such as the genitals}.
Rash starts as a flat sore, which develops into a blister filled with liquid that may be itchy or painful.
As the rash heals, the lesions dry up, crust over and fall off.
Some people may have one or a few skin lesions and others have hundreds or more.
These can appear anywhere on the body including:
palms of hands and soles of feet
face, mouth and throat
groin and genital areas
anus.
Note: Blisters are a feature of Chicken Pox but chicken pox is not usually associated with Swollen Lymph Nodes
Secondly Mpox blisters are mainly on palms and soles
Latent period:
The time from exposure to the onset of symptoms ranges from 3 -17 days,
Duration:
symptoms last from 2-4 weeks.
Symptoms can be severe, especially in children, pregnant women, or people with suppressed immune systems.
Transmission:
Close contact includes
🤝◆ skin-to-skin (such as touching or sex)
🥰◆ mouth-to-mouth, or (Lip Kissing)
😘◆ mouth-to-skin contact (such as kissing),
😫😤◆ face-to-face with someone who has mpox (such as talking or breathing close to one another, which can generate infectious respiratory particles).
◆Occasionally surface touch to abraded skin, 📞mucus membranes like nose, eyes so Handwashing is important .
Hand wash with Soap Water or Alcohol Based sanitizer.
Avoid
◆ Sharing Mobile Phones
◆ Sharing towels, beds linen etc
◆Usually transmitted from one person to another through contact with *infectious lesion material or fluid on the skin, in the mouth or on the genitals; this includes touching, close contact, and during sex.
🫷◆The disease is not known to spread by air respiratory route – for example, across rooms, in markets or classrooms, etc.
At Risk
-Sex workers and their clients
-Men having sex with Men
-People with Multiple sex partners
-Close contacts
-Health workers (use PPE, hand washing, mask)
Period of infectivity:
until all their lesions have crusted over, the scabs have fallen off and a new layer of skin has formed underneath, and all the lesions on the eyes and in the body (in the mouth, throat, eyes, vagina and anus) have healed too, which usually takes from 2 to 4 weeks.
🧐
Diagnostic method
Viral DNA PCR on blister Fluid/ Scraping/Scab
Differential diagnosis
Chickenpox, smallpox, Scabies
Prevention
Smallpox vaccine, hand washing, covering rash, PPE, social distancing
⚓Vaccination:
Limited human studies and some animal studies have shown protection against Mpox following vaccination with Smallpox vaccines
MVA -BN or JYNNEOS (live attenuated nonreplication vaccine given ID or SC)
Only those with high risk of exposure are advised to have vaccine.
🙋♂️
1️⃣ Does Chicken pox vaccination protect against Mpox?
No If someone has chickenpox vaccination or infection, it offers no cross protection against mpox because they are entirely different and unrelated viruses,
However, the skin lesions look the same in both. In fact, one can be confused with the other.
2️⃣ Does previous vaccination against small pox provide any protection against mpox?
Unlikely so.
Several cases of mpox have been reported in previously immunized persons with smallpox. Best is to take precautions .
Treatment
Supportive treatment, pain fever management nutrition hydration Isolation. Prevention of secondary infection
Medication
Tecovirimat, not yet freely available but as trial enrollment
Prognosis
Most people recover
Should We curtail foreign trip?
No. Just observe safe sex practices and avoid contact with high risk community
Will mpox blow up like Covid?
No.
◆Because it is DNA Virus which does not change so often
◆Vaccine already in place
◆Treatment already in place
◆High risk community is limited.
Nevertheless be informed and vigilant
