A new case of measles and the lack of vaccines resume the debate on the recurrence of controlled diseases



The Directorate for Epidemiology and Health Situation Analysis belongs to the Ministry of Health, issued an epidemiological warning after the confirmation of a new case of measles in the country.

With the last – a 36-year-old from Rosario who had been in contact with a commercial airline on March 16 with a tourist who was later confirmed to have measles – four have reported so far in 2019 in Argentina. The previous three were imported and the current one is under investigation.

In Argentina, the last endemic case of measles was recorded in 2000 and the last died because of this cause was 1998. The region in America was the first and only world to complete without measles in 2016. But the epidemiological situation reported globally and especially in some countries in the region, warns specialists about a disease he believed controlled.

"The single container of the mask virus is human, and given that we have a vaccine that is highly immunogenic, safe and effective, it can be eradicated if we are all vaccinated." The infectious physician Carla Vizzotti uneasily analyzed the increase in cases of this disease recorded in recent years.

The chairman of the Argentine community for vaccinology and epidemiology (SAVE) warned that "Brass is highly transmissible, as nine out of ten people in contact with the virus become infected and it stays in the air for two hours, so that someone can get it even without getting in touch with an infected person. "

At that time, it emphasized the infectious disease physician Pablo Bonvehí, a member of the Vaccine Commission of the Argentine Society of Infectious Diseases (SADI), that the disease "continues to be fatal for children under five (especially in malnourished children and in developing countries)".

"The biggest challenge is to maintain a very good monitoring, a quick and effective response to imported cases, so you must have a low threshold to detect reported cases and be subject to isolation and blocking. It is important to maintain vaccination coverage above 95%"he said.

Having pointed out that "it is estimated that vaccine against measles between 2000 and 2016 prevented more than 20 million deaths, making it one of the best public health funds", the specialist considered that "it is not allowed that there are cases to take a very effective prevention tool. "

"The perception of the severity of the disease is lost; People take as true concepts spreading through various social networks that speak against the vaccine, as association with the vaccine with autism, which is not the case and how they do not perceive the disease as serious, Doubt that the vaccine is wrong decides not to vaccinate their children, "says Bonvehí, who describes:" In America, there were 1052 cases in 38 cities in the state of Ceará after 13 years without an outbreak and it lasted for 20 months, including due to lack of rapid response ".

Later in 2018, Brazil was the highest number of cases (10,262), followed by Venezuela (5,643), USA (349), Colombia (188), Peru (38), Canada (28), Chile (23), Ecuador (19) , Argentina (14), Mexico (5), Antigua and Barbuda (1) and Guatemala (1). "Until the epidemiological week 52 last year, there were 16,514 cases of a disease eliminated from the region and with an effective vaccine in force, it is difficult to understand that this is happening," he said.

Thus, Bonvehí received the recommendations of the Pan American Health Organization (PAHO) to counteract the development of this disease:
– Keep 95% vaccination coverage
– Vaccine risk populations that do not have evidence of immunity or vaccination against measles and rubella
– Keep vaccination against measles and rubella
– Check imported cases
– Strengthen monitoring (it is important to detect cases quickly, isolate them and establish the corresponding blockade)
– Give a quick response to an imported case
– Identify both internal and external migration flows to facilitate their access to vaccination, according to the national system

In 2010, the World Health Organization set up three milestones on the road to the eradication of measles to be met by 2015:
– Increase systematic coverage with the first dose of the vaccine with an anti-measles component of more than 90% nationally and more than 80% at district level
– Reduce and maintain the annual incidence of measles in less than five cases per million; and
– Reduce the estimated mortality of measles by more than 95% compared to 2000 estimates

In 2012, the World Health Organization approved the Global Vaccine Action Plan with the aim of eliminating measles in four regions of the World Health Organization (WHO) by 2015 and five by 2020.

At this point, Vizzotti pointed out that "There are countries that still only have one dose in the calendar, so the possibility of eradicating the disease in the world is far away" and stopped considering the importance of compulsory vaccination "as a social good over the individual benefit". "For example, in Europe, people can decide not to be vaccinated and it generates a very big impact on public health and in fact they now assess the compulsory nature of the children before schooling in several countries and in the United States they must not be in a public place if they are not vaccinated. "exemplified the specialist, who emphasized that" in Argentina vaccination is mandatory because it is considered an individual benefit, first but also a social good that lies above the individual decision. "

Bonvehí remembered it The complete vaccination schedule for the age according to the national vaccination schedule establishes that children from 12 months to five years of age must have a dose of triple vaccine (measles, red dog and sheep) and those older than five years (including adults) They must approve two doses of triple virus vaccine . While people born before 1965 need not be vaccinated because they are considered protected because they have been in contact with the virus.

The inside senses missing vaccines

To interrupt the delivery of the vaccine doses to the meningococcus of the 11 years since August, Vizzotti assured that "meningococcal vaccines were lacking for 3, 5 and 15 month old infants and other vaccines that were delivered irregularly and in smaller amounts to HPV, chicken pox, tripleviral, rotavirus, Sabin and Salk. "

"The provinces reported that they get less money than planned and irregular and it really does affect very much what the planning of vaccination measures in the provinces are, those who have to carry out vaccination", the specialist assured, "which is of great importance to the health club," as well as the public's confidence in the health system, as there are many factors for which the coverage may fall, the truth that someone comes to a vaccination and vaccines are not available that must be provided by the national state is an unauthorized missed opportunity in our country".
