Earlier this month, a case of Monkeypox was reported in London, followed by reports of further cases in the UK and in many other countries. Understandably, people are anxious whenever an outbreak of an unusual infectious disease occurs, likely more so because of their experiences during the Covid-19 pandemic. Although we need to take the disease seriously, Monkeypox is much less of a threat to global health than Covid-19 and won’t have the same impact on societies or lead to the type of control measures we have seen for Covid-19 over the past two years.
The virus that causes Monkeypox is found primarily in small animals, like rodents, in parts of West and Central Africa – but was first identified in monkeys (hence the name). It can sometimes spread to humans and because of international travel, then spread to other parts of the world. But unlike Covid-19, which is easily transmissible and has caused huge waves of infection globally, Monkeypox spreads much more slowly, requiring close contact with an infected person or animal to spread.
Monkeypox outbreaks can generally be contained through conventional public health measures – like identifying and isolating cases early on, tracing contacts to identify people who are at risk of infection, and good infection control practices when dealing with people who are infected. We know that smallpox vaccines also provides some protection against infection and can be used if necessary in health care workers or in close contacts to reduce their risk of becoming infected. However, use of vaccination will be very limited and we won’t see it used widely in the UK.
Our public health agencies are well-placed to manage the Monkeypox outbreak in the UK. We now have much more experience in areas such as contact tracing and in isolating people with infections than we did before the Covid-19 pandemic. Although we will continue to see cases of Monkeypox in the UK and elsewhere, our public health system has the capacity to limit the outbreak and prevent it from having a major effect on our society.
The Monkeypox outbreak does however reinforce the need for the UK to maintain a strong infection control system so that we are prepared to deal with this and any future infectious diseases that may enter the country. Finally, although people should not become unduly anxious and have a very low risk of coming into contact with a person who has Monkeypox, everyone should remain vigilant and seek medical advice if they become unwell and develop an unusual skin rash.
