ProMED-mail | MEASLES UPDATE 2012 (22)

ProMED Mail is possibly THE premier infectious disease updating service in the world today, having sprung to fame during the Kikwit Ebola outbreak in 1995.  This is one of a series of posts on measles, which is documenting a very disturbing trend: the incidence of the disease is increasing in places where it should have been eradicated, because well-educated and sophisticated communities are not vaccinating their children – or themselves.


One very telling quote from the post:

“Measles is highly infectious so we must all do
everything possible to prevent the spread of it, particularly with an outbreak on our doorstep. … MMR vaccination is the only way to prevent
measles. If parents haven’t arranged for their children to be vaccinated – it’s not too late to have the jab. Parents don’t realise that measles is not just a case of a few spots – it can be a very serious illness. Symptoms include fever, cough, soreness of the eyes and a rash which spreads rapidly over the body. Serious complications affect one in 15 children. These include chest infections, fits, encephalitis (swelling of the brain), and brain damage. In very serious cases, measles can kill.”

Vaccines are safe: now use them!

30 August, 2011

At last, someone heavy has gone and nailed it down: The Scientist ( reports that

“Vaccines are safe and not the cause of autism, according to a new report from the Institute of Medicine, the health arm of the National Academies.  The panel based its conclusions on the review of more than 1,000 studies on eight vaccines commonly given to children, including those for chickenpox, meningitis, tetanus, and measles, mumps, and rubella (MMR).”

One.  Thousand.  Studies.  At least!  There’s more:

“Some serious side effects were linked to vaccines, but occurred very rarely. Among them: those who receive the chicken pox vaccine could later come down with pneumonia or meningitis if their immune systems become compromised by diseases such as cancer, and the MMR vaccine occasionally sets off brain inflammation or seizures, Nature reports. Six of the eight vaccines can also cause allergic reactions. The more serious side effects most commonly occur in children who have underlying immune problems.”

As I taught my captive second- and third-years for close on thirty years, there’s a risk-benefit calculation to be done for every vaccine, and indeed, for every drug that you or yours may be exposed to.  If there’s no benefit – because there’s no risk – then do without.  If, on the other hand, your baby stands a reasonable chance of getting seriously ill, and maybe even suffering permanent damage from getting infected by a preventable dissease – vaccinate!

And that’s rotavirus I’m talking about, not even something really nasty like measles.  I did the same survey over several years, asking 70+ students if they would give kids a vaccine that had a POSSIBLE 1/40 000 chance of causing a possibly fatal intestinal complication (intussusseption, or telescoping of the bowel) in (a) an environment where no children died of rotavirus, (b) an environment like in many places in the developing world, where 1/100 children might die.  Nearly every single one, every time, would not use it in (a), but would have no hesitation in scenario (b).

Regulars on this blog will know what I think about not vaccinating against measles.  So now, folks: reach out to a relative or a friend who espouses this utter nonsense linking vaccines to autism – and smack them solidly.  Then get their kids vaccinated.

OK, maybe not – but remonstrate with them, point them towards the evidence, tell them just how nasty some of the preventable diseases can be, and that they should realise measles, polio or rotavirus are only someone else’s plane trip away.

Measles just won’t go away

6 June, 2011

I have written before in ViroBlogy about measles resurging in Africa (see: Measles in Zimbabwe from January 2010) – and now Larry Madoff, the Editor of the very worthy ProMED, makes the case that it is resurging all over.  And in the case of developed countries, largely because of simple stupidity.

From Larry:

Once nearly eradicated in much of the developed world, measles outbreaks are becoming more frequent in 2011. They are the result of increased global travel, lower rates of vaccination in poorer counties – and parents choosing not to vaccinate their children in the U.S., Europe and elsewhere [my emphasis] because of the now widely discredited myth that the measles, mumps and rubella vaccine causes autism.

Whenever people are on the move, there are risks of infectious diseases moving with them.

… [ fundraising message removed: go here to donate]

Measles kills an estimated 165,000 people each year, mostly in poor countries. Since January, however, measles outbreaks reported on ProMED mail have occurred not only in poorer nations such as Bangladesh, Somalia, and Pakistan, but in such countries as France, Spain, England, Canada, Australia, New Zealand, and within the U.S. from Massachusetts to Utah, Minnesota to New Jersey. An outbreak of measles in the Canary Islands and several South American countries, in fact, appears to be the result of unvaccinated British and German tourists bringing the disease to their shores.

As I said, then: stupidity, in the case of unvaccinated tourists.  And lack of vaccine or problems in delivery in the case of the poorer nations.

The first is easy to fix: simply don’t let any tourists in without proof of measles vaccination, as presently happens in Brazil for yellow fever, for example.  It would be done for all the wrong reasons, but hey, whatever works!

The second…is harder.  Measles vaccines are good: they are effective and safe, whether given singly or in combination (eg: measles-mumps-rubella; MMR) – and pretty cheap; cheap enough to be included in the free Extended Programme of Immunisation (EPI) bundle in many countries.  But the simple fact is that they are not getting to many of the folk who need them – and given that you need a minimum of 80% coverage to get “herd immunity”, the virus just keeps on being transmitted around.

And measles is not a trivial disease, whatever the lay population thinks: if it can kill or cause severe complications in healthy, well-fed children, imagine how much worse the consequences of infection are in malnourished, sickly children. As mentioned above, 165 000 people – and mainly children – die every year from measles.

From the WHO Measles Fact Sheet:

Measles is a highly contagious vaccine-preventable disease caused by the measles virus, a member of the genus Morbillivirus in the family Paramyxoviridae. It is spread by droplets or direct contact with nasal or throat secretions of infected persons; less commonly by airborne spread or by articles freshly soiled with secretions of nose and throat. Measles is one of the most readily transmitted communicable diseases and probably the best known and most deadly of all childhood rash/fever illnesses. [my emphasis].

The scale of the problem can be seen here:

Anywhere that isn’t blue has less than 90% coverage – and look at Africa…mostly 50-79% coverage, and that is simply not enough.

Look again at the complications of natural measles infections – from the CDC Measles Complications page:

About 30% of measles cases develop one or more complications, including

  • Pneumonia, which is the complication that is most often the cause of death in young children.
  • Ear infections occur in about 1 in 10 measles cases and permanent loss of hearing can result.
  • Diarrhea is reported in about 8% of cases.

These complications are more common among children under 5 years of age and adults over 20 years old.

Even in previously healthy children, measles can be a serious illness requiring hospitalization. As many as 1 out of every 20 children with measles gets pneumonia, and about 1 child in every 1,000 who get measles will develop encephalitis. (This is an inflammation of the brain that can lead to convulsions, and can leave the child deaf or mentally retarded.) For every 1,000 children who get measles, 1 or 2 will die from it. Measles also can make a pregnant woman have a miscarriage, give birth prematurely, or have a low-birth-weight baby.

In developing countries, where malnutrition and vitamin A deficiency are common, measles has been known to kill as many as one out of four people. It is the leading cause of blindness among African children. [my emphases]

Sub-acute sclerosing panencephalitis (SSPE) is a very rare, but fatal degenerative disease of the central nervous system that results from a measles virus infection acquired earlier in life. Analysis of data from an outbreak of measles in the United States during 1989-1991 suggests a rate of 4-11 cases of SSPE per 100,000 cases of measles. A risk factor for developing this disease is measles infection at an early age.

If this doesn’t scare you, then you are invincibly ignorant.  Or simply stupid.  Which the Bill & Melinda Gates Foundation is not – they have supported new measles vaccine development since 2000; they are also recently involved along with the Lions Club International Foundation in the Measles Initiative, which is:

“…a worldwide effort to protect children from measles and strengthen routine immunization services. UNICEF, World Health Organization (WHO), U.S. Centers for Disease Control (CDC), American Red Cross, and the United Nations Foundation are among the organizations contributing to these efforts since 2001.”

From their site:

An estimated 164,000 people – 450 a day – died from this easily preventable disease in 2008. Costing less than US $1 to vaccinate a child, the measles control strategy represents one of the most cost-effective health interventions available.

Yet, many developing countries that are facing multiple health challenges have limited funds, making financial support from the Measles Initiative critical. A steep decline in donor investment has resulted in a significant funding gap. Unless conditions improve, the shortfall will put the goal and millions of children at risk.

We can eradicate measles.  We really, really can – but it starts with vaccinating your children, and yourself.  Then helping vaccinate others.
