Every winter,\u00a0gastroenteritis season\u00a0returns to\u00a0daycares and schools. Highly contagious, this infection that parents fear can be alarming, especially in infants and young children. The real danger?\u00a0Dehydration.<\/p>\n\n\n\n

Winter and Young Children: The Perfect Storm for Gastroenteritis<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

When cold weather sets in,\u00a0cases of gastroenteritis rise sharply. According to the\u00a02024 report from the Sentinelles network<\/a>, activity begins to increase from\u00a0late November, peaks between\u00a0mid-December and late January, and then gradually declines until\u00a0mid-March.<\/p>\n\n\n\n

Extremely contagious, gastroenteritis particularly affects\u00a0babies and young children, especially those who attend\u00a0daycare or other group settings.<\/p>\n\n\n\n

Why Is Gastroenteritis More Common in Winter?<\/summary>
\n

The viruses responsible (rotavirus, norovirus) survive better in\u00a0cold and humid environments. Cold weather also encourages people to spend more time\u00a0indoors. Close contact in enclosed spaces (daycares, schools, family gatherings, etc.) significantly increases\u00a0virus transmission.<\/p>\n<\/div><\/details><\/div>\n\n\n\n

How Is Gastroenteritis Transmitted?<\/summary>
\n

Gastroenteritis is\u00a0mainly transmitted through contact. The virus is present in the\u00a0stool or vomit\u00a0of an infected person. It spreads when\u00a0tiny contaminated particles\u00a0are transferred from the\u00a0hand to the mouth, either directly or via\u00a0objects and surfaces\u00a0such as\u00a0toys, door handles, pacifiers, or bottles.<\/p>\n\n\n\n

It can also be transmitted through\u00a0direct contact\u00a0with an infected person, including\u00a0hugging, diaper changes, or helping with meals.<\/p>\n<\/div><\/details><\/div>\n\n\n\n

Why Does Gastroenteritis Affect Babies and Young Children More Often?<\/summary>
\n

Young children\u00a0frequently put their hands, toys, and other objects into their mouths\u00a0and are not yet able to\u00a0wash their hands properly. This is why, in\u00a0daycare centers or schools, a single sick child can easily\u00a0infect several others within just a few hours.<\/p>\n\n\n\n

Similarly, when a child becomes ill, the virus often\u00a0spreads to the entire household.<\/p>\n<\/div><\/details><\/div>\n\n\n\n

How Long Does the Virus Survive?<\/summary>
\n

These viruses are\u00a0extremely resilient. They can survive\u00a0for several hours to several days\u00a0on\u00a0skin and surfaces.<\/p>\n<\/div><\/details><\/div>\n<\/div>\n\n\n\n

How to Tell If Your Baby Has Gastroenteritis: A Closer Look at the Symptoms<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

\ud83e\udd2e Baby Vomiting or Feeling Nauseous<\/h3>\n\n\n\n

Vomiting is often\u00a0one of the first symptoms\u00a0to appear in cases of\u00a0gastroenteritis. There is\u00a0no strict rule regarding frequency: some babies may vomit only once at the beginning, while others may vomit\u00a0after every attempt to eat or drink.<\/p>\n\n\n\n

Parents often wonder\u00a0how long vomiting lasts in babies with gastroenteritis. In most cases, the\u00a0active vomiting phase lasts no more than 12 to 24 hours. Some children may not vomit at all or may only experience\u00a0nausea. If a baby is too young to express this, nausea can be harder to detect, but\u00a0loss of appetite or complete refusal to eat\u00a0can be important warning signs.<\/p>\n\n\n\n

\ud83d\udca9 Baby Has Diarrhea<\/h3>\n\n\n\n

Diarrhea usually appears\u00a0after the first episodes of vomiting\u00a0(within\u00a06 to 24 hours, sometimes later) but tends to\u00a0last much longer, on average\u00a04 to 7 days. Stools are\u00a0loose to very watery, sometimes\u00a0almost like water.).<\/p>\n\n\n\n

\ud83e\udd12 Baby Has a Fever<\/h3>\n\n\n\n

In\u00a0babies and young children, gastroenteritis is often accompanied by\u00a0fever. This is not unusual: fever indicates that the body is\u00a0fighting the virus. It may appear\u00a0with the first episodes of vomiting\u00a0or\u00a0a little later, and usually lasts\u00a0one to two days.<\/p>\n\n\n\n

When a baby has a fever, what matters most is the child\u2019s\u00a0overall condition, rather than the exact number shown on the thermometer.
A baby who remains\u00a0slightly smiling, alert, and willing to drink\u00a0is far more reassuring than a baby who appears\u00a0lethargic, drowsy, or unusually unresponsive.<\/p>\n\n\n\n

Did You Know?<\/strong><\/p>\n\n\n\n

Even a\u00a0moderate fever\u00a0can\u00a0speed up dehydration: the body sweats more and\u00a0loses fluids more quickly.<\/p>\n<\/div>\n<\/div>\n\n\n\n

All of these symptoms can lead to severe dehydration<\/strong>, which can be dangerous for a baby<\/strong> if nothing is done to prevent it.<\/strong><\/p>\n\n\n\n

How Should You Respond?<\/h2>\n\n\n\n

\ud83d\udca6 Rehydrate, Rehydrate, Rehydrate!<\/h3>\n\n\n\n

This is\u00a0the most important thing in cases of gastroenteritis. Between\u00a0vomiting, diarrhea, fever, and loss of appetite, a baby can lose\u00a0a significant amount of fluids. These losses must be\u00a0replaced, as the consequences can be serious if nothing is done.<\/p>\n\n\n\n

Water is\u00a0essential for proper body function. If dehydration is left untreated,\u00a0blood circulation becomes less efficient, organs receive\u00a0less oxygen and fewer nutrients, and this can gradually\u00a0disrupt the function of the kidneys, brain, and heart.<\/p>\n\n\n\n

Did You Know?<\/strong><\/p>\n\n\n\n

Babies\u00a0become dehydrated faster than adults\u00a0because their bodies contain\u00a0a higher proportion of water, they\u00a0lose more fluids each day, and their\u00a0still-immature kidneys\u00a0are less able to compensate for these losses. As a result,\u00a0dehydration can develop within just a few hours.<\/p>\n<\/div>\n<\/div>\n\n\n\n
