A study published online in the journal JAMA Network Open found that MRI scans performed on healthy newborns. At the same time, they slept indicated that babies facing social disadvantages such as poverty tended to be born with smaller brains than babies whose mothers had higher household incomes.
Manila, August 16 – At least 300 children aged 5-9 have died in the recent Dengue outbreak in the Philippines, Save the Children said today, amid fears the epidemic could claim many more lives before its brought under control. In the first seven months of 2019, some 170,000 people were infected with the disease, killing 720 people – 42 percent were children between 5 and 9 years old. Compared to the same period in 2018, this years dengue caseload is 97 per cent higher. The virus is disproportionately affecting children and young people with a staggering 73 per cent of recorded cases under the age of 19.
Albert Muyot, ceo of Save the Children in the Philippines, said: “Hundreds of children have sadly already died, we expect the numbers to rise. The rainy season started late and will continue this month, creating the perfect breeding ground for dengue mosquitoes.
“Children are particularly a vulnerable to the disease because their immune systems are weaker than adults and they tend to play outside where theres less protection against the mosquitos. Schools in particular are a hotbed of dengue because many have open windows and lack mosquito repellents.
“It is extremely important that health authorities step up their information campaigns in schools, communities and other places where people come together, so people know what to do if they suspect dengue. Also, the government must step up their fumigation campaign to kill adult dengue mosquitoes in densely populated areas.
“In the Philippines, we are working with schools and communities to improve awareness on how to prevent infection. To save lives, children need extra protection. Wearing long sleeves and trousers is one of the simple measures to protect against being bitten. Early diagnosis is critical and we are raising awareness of those symptoms, like fever and body pain, and encouraging all parents to take their children to hospital immediately if they have concerns.
“Save the Children is referring child dengue cases to health centers in vulnerable communities in Navotas, Caloocan and Malabon as well as in conflict-affected provinces in Bangsamoro Automous Region in Muslim Mindanao (BARMM).”
Notes to editors:
- Dengue causes flu-like illness, including a sudden high fever coming in separate waves, pain behind the eyes, muscle, joint and bone pain, severe headache, and a skin rash with red spots. People with symptoms get ill between 4 to 7 days after a bite from an infected Aedes mosquito.
- The illness can become the fatal Severe Dengue, characterised by severe abdominal pain, vomiting, diarrhoea, convulsions, bruising, uncontrolled bleeding, and high fever which can last from 2 to 7 days.
- Complications can lead to circulatory system failure, shock, and death.
- There were 167,607 dengue cases between January-July 2019, up from 85,011 in the same period in 2018.
- Of the 167,607 recorded cases of dengue between January and July 2019, 121,942 were under the age of 19.
- On August 6th, the government declared a national dengue epidemic.

Covid: Woman caught virus twice within record 20 days
A 31-year-old healthcare worker caught Covid twice within 20 days – the shortest-known gap between infections, Spanish researchers have claimed.
Tests show the woman was infected with two different variants – Delta in late December and then Omicron in January.
This shows that even if you have had Covid before, you can still be infected again even if fully vaccinated, the researchers say.
Reinfections in the UK require 90 days between positive tests.
Based on that definition, health officials say nearly 900,000 people have potentially been infected twice with Covid up to the start of April.
It is difficult to pin down an exact number, because only whole genome sequencing can confirm the infections are caused by different strains, and very few positive tests go through this process.
The Spaniard did not develop any symptoms after her first positive PCR test, but less than three weeks later she developed a cough and fever which prompted her to take another test.
When the tests were analysed further, they showed the patient had been infected by two different strains of coronavirus.
In a presentation at the European Congress of Clinical Microbiology and Infectious Diseases, study author Dr. Gemma Recio said the case highlighted that Omicron can “evade the previous immunity acquired either from a natural infection with other variants or from vaccines”.
She said: “In other words, people who have had Covid-19 cannot assume they are protected against reinfection, even if they have been fully vaccinated.
“Nevertheless, both previous infection with other variants and vaccination do seem to partially protect against severe disease and hospitalisation in those with Omicron,” added Dr Recio, from the Institut Catala de Salut, Tarragona in Spain.
She said monitoring reinfections in people who were fully vaccinated was important, and would help the search for variants which evade vaccines.
Covid reinfections rose sharply in December 2021 after the much more infectious Omicron variant emerged, and there was another increase when a slightly different version of it, called BA.2, appeared in early March.
Before that, 1% of all cases recorded in the UK were labelled as second infection – but that has now gone up to 11%.
Most are likely to be people infected by the Alpha or Delta variants and then infected again by the more contagious Omicron.
Scientists predict that eventually everyone will catch Covid twice, and probably many more times over the course of their lifetime.

Poverty, crime linked to differences in newborns’ brains
MRI scans of full-term newborns born to mothers living in poverty revealed smaller volumes across the entire brain — including the cortical grey matter, subcortical grey matter and white matter — than found in the brains of babies whose mothers had higher household incomes.
The brain scans, conducted only a few days to weeks after birth, also showed more miniature folding of the brain among infants born to mothers living in poverty. Fewer and shallower folds typically signify brain immaturity. The healthy human brain folds as it grows and develops, providing the cerebral cortex with a more extensive functional surface area.
A second study of data from the same sample of 399 mothers and their babies — this one published online in the journal Biological Psychiatry — reports that pregnant mothers from neighbourhoods with high crime rates gave birth to infants whose brains functioned differently during their first weeks of life than babies born to mothers living in safer neighbourhoods.
Functional MRI scans of babies whose mothers were exposed to crime displayed weaker connections between brain structures that process emotions and structures that help regulate and control those emotions. Maternal stress is believed to be one of the reasons for the weaker connections in the babies’ brains.
“These studies demonstrate that a mother’s experiences during pregnancy can have a major impact on her infant’s brain development,” said Christopher D. Smyser, MD, one of the principal investigators. “Like that old song about how the ‘knee bone is connected to the shin bone,’ there’s a saying about the brain that ‘areas that fire together wire together.’ We’re analysing how brain regions develop and form early functional networks because how those structures develop and work together may impact long-term development and behaviour.”
Babies in the study were born from 2017 through 2020, before the COVID-19 pandemic. Smyser, a professor of neurology, paediatrics and radiology, said that babies are fed when they arrive for scans because they tend to fall asleep after eating to scan newborns during the first few weeks of life successfully. They are then snugly swaddled into blankets and a device that helps keep them comfortable and still. The brain scans take place while they sleep.
In the study involving the effects of poverty, the researchers focused on 280 mothers and their newborns. First author Regina L. Triplett, MD, a postdoctoral fellow in neurology, had expected to find that maternal poverty — referred to in the paper as a social disadvantage — could affect the babies’ developing brains. But she also expected to see the effects of psychosocial stress, which includes measures of adverse life experiences and anxiety and depression.
affected the brain across many of its structures, but there were no significant effects related to psychosocial stress,” Triplett said. “Our concern is that as babies begin life with these smaller brain structures, their brains may not develop as healthy as the brains of babies whose mothers lived in higher-income households.”
In the second study, which implicated living in high-crime neighbourhoods as a factor in weaker functional connections in the brains of newborns, first author Rebecca G. Brady, a graduate student in the university’s Medical Scientist Training Program, found that unlike the effects of poverty, the results of exposure to crime were focused on particular areas of the babies’ brains.
“Instead of a brain-wide effect, living in a high-crime area during pregnancy seems to have more specific effects on the emotion-processing regions of babies’ brains,” Brady said. “We found that this weakening of the functional connections between emotion-processing structures in the babies’ brains was robust when we controlled for other types of adversity, such as poverty. It appears that stresses linked to crime had more specific effects on brain function.”
Reducing poverty and lowering crime rates are well-established goals in public policy and health. And the researchers believe protecting expectant mothers from crime and helping them out of poverty will do more than improve brain growth and connections in their babies. But if social programs that aim to help people reach their full potential are to succeed, the researchers said the policies must focus on assisting people even before they are born.
“Several research projects around the country are now providing money for living expenses to pregnant mothers. Some cities have determined that raising pregnant mothers out of poverty is good public policy,” Smyser said. “The evidence we’re gathering from these studies certainly would support that idea.”
