Infectious disease warning
records high cases worldwide
A series of measles warnings have been issued across Australia in recent weeks
and the US and UK have also faced wider measles outbreaks.
In fact, WHO reported a 45-fold increase in measles cases in Europe last year
with 42,200 cases recorded in 2023 compared to 941 in 2022.
In South Asia
India and Pakistan recently reported outbreaks.
What is measles?
Measles is a highly contagious viral disease that spreads through spray
when an infected person coughs or sneezes. They are so contagious that
if an infected person contacts 10 unvaccinated people, the infection
can be transmitted to nine of them.
Symptoms can take about 10 to 12 days after a person's exposure to the virus.
Although measles is characterized by a rash
symptoms are usually similar to colds at first, including fever
runny nose, fatigue, pain or red eyes. Rashes appear two
or three days later and spread from the face to the lower body.
Sometimes measles can lead to secondary infections such as ear infection
diarrhoea or pneumonia. In rare cases can cause encephalitis.
In severe cases
measles can lead to hospitalization and death.
Vaccination is a highly effective strategy for measles protection.
Two doses of the MMR vaccine provide protection against measles
mumps and rubella.
Once vaccinated, the chance of measles is very low
and a person is considered protected for life.
However, about one in 100 vaccinated people may be infected with measles
if exposed to the virus. Although it is not entirely clear why this happened
the infection in the vaccinated person is generally mild.
Globally :
there has been a decrease in children's vaccinations over the course of
the COVID pandemic. This is likely due to a range of factors
including declining confidence in vaccines and misinformation
and disrupting access to them.
In Europe
the proportion of children who received a first dose of
the MMR vaccine fell from 96% in 2019 to 93% in 2022
and from 93% to 91% for the second dose.
This is important because almost 95% vaccination coverage
is needed to achieve herd immunity to measles.
In the United Kingdom, health authorities have expressed concern
about the number of children who have not been vaccinated.
As of September 2023, the Australian Government has reported
immunization rates in all children's vaccinations of 93.26%
for children aged 1, 91.22% for children aged 2 and 94.04% for children aged 5.
It is never too late to get vaccinated against measles if you miss it as a child
or you are not sure if you have taken two doses, according to experts.
If you are not sure of your vaccination status, you can ask your GP
or check your vaccination record.
