Migrants and refugees arriving in Europe are likely to be healthy but risk falling sick due to poor living conditions in their host countries, the World Health Organization (WHO) said in a first-ever report on migrants’ health.

WHO regional director for Europe, Zsuzsanna Jakab, said on Monday (January 21) that refugees and migrants in Europe do not bring “exotic” diseases but are in higher risk to of getting sick because they lack access to health care.

Poor living conditions also increase their risk for cardiovascular diseases, stroke and cancer, though they are less affected than their host populations on arrival, WHO said.

The report said that a significant proportion of migrants and refugees who are HIV positive acquired the infection after they arrived in Europe. Despite a widespread assumption to the contrary, there is only a very low risk of refugees and migrants transmitting communicable diseases to their host population.

Jakab said that in some European countries “citizens estimate that there are three or four times more migrants than they are in reality”. — Reuters

Plastic particles in drinking water present ‘low’ risk – WHO

Robie de Guzman   •   August 23, 2019

Microplastics contained in drinking water pose a “low” risk to human health at current levels, but more research is needed to reassure consumers, the World Health Organization (WHO) said on Thursday (August 22).

Studies over the past year on plastic particles detected in tap and bottled water have sparked public concerns, but the limited data appears reassuring the U.N. agency said in its first report on potential health risks associated with ingestion.

Microplastics enter drinking water sources mainly through run-off and wastewater effluent, the WHO said. Evidence shows that microplastics found in some bottled water seem to be at least partly due to the bottling process and/or packaging such as plastic caps, it said.

It added however that the current and available studies on the toxicity of plastic parts are limited, and also have not used standardized methods enabling scientists to have reproducible and comparable metrics, and that more studies are needed to be more conclusive on certain of the issues.

Microplastics pose three threats, a physical one, a chemical and the third is about bacterial colonization.

The majority of plastic particles in water are larger than 150 micrometers in diameter and are excreted from the body, while the vast majority of smaller ones are likely to be excreted too, there still remains concern. WHO technical experts reported that more research needs to be conducted to know more about what is being absorbed, the distribution and their impacts.

The chemical hazard, experts have looked at the concentrations found in marine microplastics and chose a worst-case scenario saying we would ingest the highest possible concentrations. According to WHO, whatever the chemical, the exposure level was a lot safer than any threshold of risks.

Bacterial colonization, health experts say there are so many particles in the environment bacteria might adhere to, that microplastics would make a negligible contribution to any microbioflora that would be released and pose a risk.

For this report, however, despite the flaws, they say they worked with worst-case scenarios and are confident that the risk would remain low should some data change.

The WHO recommended for consumers to keep on consuming tap or bottled water, provided it is correctly treated, and didn’t recommend for any regulations to be put in place. It also called for more studies, investigating the potential cumulative effects of the ingestion of microplastics present in food, air, water.

The biggest overall health threat in water is from microbial pathogens —including from human and livestock waste entering water sources — that cause deadly diarrhoeal disease, especially in poor countries lacking water treatment systems, the WHO said.

Some 2 billion people drink water contaminated with faeces, causing nearly 1 million deaths annually, Gordon said, adding: “That has got to be the focus of regulators around the world.”

Plastic pollution is so widespread in the environment that you may be ingesting five grams a week, the equivalent of eating a credit card, a study commissioned by the environmental charity WWF International said in June.

That study said the largest source of plastic ingestion was drinking water, but another major source was shellfish. (Reuters)

Filipinos in Macau advised to observe strict measures vs. Ebola virus

MANILA, Philippines – Filipinos living and working in Macau as well as those who wish to travel to the south China autonomous region are advised to observe intensified measures by Macau Health authorities against cross-border spread of the deadly Ebola virus.

In a public advisory on Friday (August 9), the Department of Foreign Affairs (DFA) citing the Philippine Consulate General in Macau SAR, announced that the Macau Health Services will be implementing strengthened response measures at its borders and ports for the early patient detection and prevention against the virus.

The DFA said the advisory was in response to the World Health Organization’s (WHO) announcement of a “public health emergency of international interest” for Ebola outbreak in the Democratic Republic of Congo.

With the strengthened response measures in place, all passport holders from Ebola-stricken regions will subject for questioning and inspection by border crossing health workers.

Travelers from countries and regions affected by the outbreaks will be immediately referred to the Conde de São Januário Hospital Center to undergo evaluation and tests should they show suspicious symptoms of Ebola.

On the other hand, should travelers show no signs of symptoms, Health Services agents will follow the medical condition daily by phone call.

For further concerns, Filipinos in Macau are encouraged to call the Macau Health Services Communicable Disease Hotline at 28 700 800 or coordinate with the Philippines Consulate General’s Office at +853 6698-1900.

Dengvaxia won’t bring dengue cases down – DOH

Maris Federez   •   August 8, 2019

The controversial dengue vaccine, Dengvaxia

The Department of Health (DOH) on Thursday maintained that Dengavaxia is not the answer to the problem of the high incidence of dengue in the country.

DOH spokesperson and Officer in Charge of the Food and Drug Administration, Usec. Eric Domingo explained that dengue is not like any other disease where vaccination is the only solution.

He stressed that Dengvaxia is still not a registered drug in the country and its efficacy is not yet fully proven.

“This vaccine is not for an outbreak response. It’s designed for future use sa mga taong nagka- dengue na dati [for people who have had dengue before],” Domingo said.

A World Health Organization (WHO) report showed that “Dengvaxia was first licensed in Mexico in December 2015 for use in individuals 9-45 years of age living in endemic areas, and is now licensed in 20 countries.”

It was then used in 11 countries in 2016, including the Philippines.

But it was only in September 2018 that the WHO recommended that Dengvaxia be only administered to children who were previously infected with dengue, adding that it is dangerous for those who have not yet gotten the disease.

This caused among the public, as well as, experts as the Philippines is the only country who had used Dengvaxia vaccination on a wider scope, with more than 800,000 children inoculated.

The DOH maintained that there is still no concrete study to date that claimed that children who are vaccinated with Dengvaxia will never be infected with dengue.

“It’s very difficult because you’re tested and then you’re positive but you’re actually false positive. Then if you give the Dengvaxia, who knows that the severe dengue reaction will not occur in a particular individual. So, there’s a risk, in other words,” DOH Secretary Francisco Duque III said.  (with details from Aiko Miguel) /mbmf
