Today we are going to talk about a virus that is common among many people, especially young children, but we sometimes don't pay much attention to it. Do you remember when you suddenly feel sick, vomit, and pass out? That is what happens with this Astrovirus. It feels like a "stomach ache" or a "stomach flu," but it has nothing to do with the flu we know as `(Influenza)`.
What exactly is this Astrovirus?
Simply put, Astrovirus is a common virus that can cause diarrhea, or loose stools. It is a type of gastroenteritis, which is an inflammation of the stomach and intestines. Most of the time, the illness is not serious and gets better quickly. It is especially common in children under 5 years of age, people over 65, and people with weakened immune systems.
Imagine, when you look at this virus under a microscope, it looks like a star. The Greek word "astro" means "star," which is why this virus got the name "astrovirus." Isn't it a pretty name? But what it does is a little annoying.
How common is this?
Astrovirus is actually very common . Studies show that by the age of 9, about 90% of children have had at least one astrovirus infection. Adults are less likely to get it. This is because they have been exposed to it as children and have developed immunity (i.e., protection from the disease).
What are the symptoms of Astrovirus?
The main symptom is loose stools (diarrhea) . This is usually not severe. In addition, the following may occur:
- Nausea (feeling like your stomach is churning)
- Vomiting
- Stomach ache
- Fever
However, some people can be infected with this Astrovirus without having any symptoms. That means they don't even know they have the disease.
How long does it take for the virus to enter the body and cause illness?
We call this the "incubation period." That is, the time it takes for the virus to enter your body and for you to start getting sick. In the case of Astrovirus, this period is about four to five days .
How does this Astrovirus infect us?
This is very important. Astrovirus is transmitted through the fecal-oral route . Simply put, it occurs when virus-laden fecal particles enter our mouths, either unknowingly or unintentionally. There are several ways this can happen:
- From dirty water: This means drinking untreated water, and sometimes from swimming in lakes, rivers, public swimming pools, and water parks.
- From unclean foods: improperly washed fruits and vegetables (even things like gotu kola and mukunuvenna that we buy from the store should be washed properly), unpasteurized milk and foods made from them.
- From dirty surfaces and items: This can be transmitted when we touch objects and surfaces that have been touched by someone with Astrovirus, or when caring for or changing a diaper of someone with this disease (especially a young child).
Imagine, if a small child puts a toy in their mouth and it has a virus on it, and another child then touches that toy and then puts their hand in their mouth, how likely is it that the disease will spread?
Is Astrovirus contagious?
Yes, Astrovirus is definitely contagious. It can spread very easily from person to person. For example, if someone who is sick uses the bathroom and prepares food without washing their hands properly, it can also be transmitted to those who eat that food. If someone in your household has symptoms of this type of stomach illness, it is very important to wash their hands frequently, keep surfaces clean, and maintain a minimum distance for a few days.
Who is at higher risk of developing this?
Although anyone can get Astrovirus, the following people are at a slightly higher risk:
- Young children under 5 years old.
- People over 65 years of age.
- People with weakened immune systems (for example, those infected with HIV, those with certain types of cancer, or those taking immunosuppressant medications).
Due to these risk factors, outbreaks can occur in places like daycare centers and long-term living facilities, because these places house high-risk groups.
What complications can this cause?
Adults and children with healthy immune systems are less likely to develop complications from Astrovirus. However, if your immune system is weak, this virus can sometimes affect your central nervous system (that is, your brain and spinal cord) and cause conditions like ``Encephalitis`` (inflammation of the brain) and ``Meningitis`` (inflammation of the meninges). Therefore, people with weakened immune systems should be very careful.
How do you recognize this? (Diagnosis)
Doctors usually don't do any special tests to look for Astrovirus. They only suspect it's Astrovirus based on your symptoms and the absence of other illnesses.
However, if your symptoms are more severe, or if you have a weakened immune system, your doctor may recommend a stool test.
For this stool test, your doctor will give you a clean bottle and show you how to collect a stool sample. It will then be sent to a lab, where they will check for the presence of Astrovirus. The tests they may use are:
- Enzyme Immunoassay (EIA) test: This tests for viral antigens (parts of the virus itself) in the stool.
- Polymerase Chain Reaction (PCR) test: This tests for the presence of the virus's genetic material in stool.
Both of these tests are very sensitive, so they can detect even very small amounts of virus in the stool.
What is the treatment for this?
In fact, there are no specific antiviral medications to kill Astrovirus. Most people with healthy immune systems get better without any treatment.
The most important thing is to drink plenty of water and fluids when you or your child has diarrhea. The key is to prevent dehydration.
If your symptoms are severe, your doctor may prescribe oral rehydration solutions, intravenous hydration, or antidiarrheal medications. However, these medications should only be taken under medical supervision.
If you have an underlying condition that lowers your immune system, your doctor will help you manage that condition, which will make it easier for you to fight off an Astrovirus infection.
What to do if you get Astrovirus? How long will it last?
Astrovirus usually does not require medical treatment. You can take care of yourself at home by drinking plenty of fluids and monitoring your symptoms. If you have a weakened immune system, your doctor may monitor you to see if your symptoms worsen or if complications develop.
For most people, this Astrovirus infection gets better within one to four days .
What are the ways to survive this?
The best way to protect yourself from this is to wash your hands often and thoroughly , especially before eating and after using the bathroom. Remember that hand sanitizers are not very effective against this Astrovirus. So it is best to wash your hands thoroughly with soap and water.
You can also do these things to reduce the spread:
- Don't go swimming if you have diarrhea. Wait at least two weeks after the diarrhea stops.
- If you bathe in lakes, rivers, or public swimming pools, be careful not to get water in your mouth.
- Do not drink untreated water or unpasteurized milk.
- Wash fruits and vegetables thoroughly with clean water. Wash, peel, or cook before eating.
- If you have any doubts about drinking or cooking water, use bottled water.
- Teach young children the importance of washing their hands from a young age. Wash your hands after using the toilet and before eating.
How do I take care of myself? (Self-care)
There are several ways you can take care of yourself when you have diarrhea caused by Astrovirus:
- Drink plenty of fluids. Water, broth, sports drinks, or oral rehydration solutions (such as Pedialyte) are good choices. Try to eat as much nutritious food as possible.
- Avoid drinking or eating things that increase diarrhea and dehydration (alcohol, caffeine, etc.).
- Over-the-counter medications such as `(Loperamide - Imodium)` and `(Bismuth Subsalicylate - Pepto-Bismol, Kaopectate)` can help stop diarrhea. But be sure to ask a doctor before taking these. Especially `(Loperamide)` can cause heart rhythm problems if taken in large doses. If you have heart disease or liver disease, tell your doctor before taking it.
Most importantly: Do not give any medicine to young children or babies without first consulting their pediatrician. Some medicines that are safe for adults may not be suitable for young children.
When should I see a doctor?
It's a good idea to see a doctor if your symptoms last more than a few days, or if you have watery bowel movements (diarrhea) several times a day. If you have a weakened immune system, see a doctor as soon as you develop any symptoms of an infection.
When do you need to go to a hospital urgently (ETU) ?
If you have any of these symptoms, go to the nearest emergency room (ER) immediately:
- If you can't keep any food or drink down.
- If you have watery bowel movements more than ten times a day.
- If you have symptoms of severe dehydration, this means:
- Confusion
- Weakness, light-headedness, faintness
- Feeling dizzy when you stand
- Not peeing or barely peeing
- Dark-colored pee
What questions should you ask the doctor?
When you see a doctor, it's helpful to ask these questions:
- How can I manage my symptoms at home?
- What medications can I take for my symptoms?
- What should I eat and drink? What should I not eat or drink?
- What is the best way to stay hydrated?
- What should I do if my symptoms get worse or change?
- What symptoms should I call you for or go to the emergency room if I develop them?
Finally, things to remember
Astrovirus is the most common cause of diarrhea in young children. But most of the time, it's not serious and will go away on its own in a few days. The best thing you can do until you get better is to drink plenty of fluids and eat small meals.
If your symptoms are severe, last for several days, or if you have a weakened immune system, see a doctor without hesitation. That way, you can get the help you need.
