Winter “Ichika”? You may get sick in any of these four viruses -national

Sneezing, fever, chills, vomiting, cough -not only viruses that bring a rough confusion this winter. It's a combination of four major illnesses: influenza,, Respiratory cell virus (RSV),, COVID-19 (New Coronavirus infection and Norovirus。

In the United States Some health experts The simultaneous spread of these four viruses is called the “quadruple”.

But is the same spread in Canada?

“I think we are experiencing something very similar,” said Matyu Miller, the director of the Institute of Institute of Michael G. Deglute at Hamilton, Hamilton, Ontario. I did it.

“Our low COVID level is as high as many other viruses approaching peaks. In the case of RSV, it looks like we have already reached its peak, but influenza A. The case is still shooting, “he told Global News.

In Canada, these three respiratory diseases are increasing, but there are also other viruses that are increasing. NorovirusIt is also known as a stomach bug.

Full -scale winter virus

Influenza, RSV, and COVID-19 are primarily spreading to respiratory drops, but noroviruses are mainly transmitted through contaminated surface and are very resilient, so they can withstand hands-to-hand disinfectants. can.

In the cold winter, as people spend more time indoors, the risk of spreading all four viruses increases, creating an optimal state for the rapid increase in infections.

“Sure, these months are the normal peak we call it the respiratory virus season, which is for various reasons. One is that winter weather conditions support virus transmission capabilities. Therefore, the lack of cold and relative humidity will help the viruses live on the surface and send them well in the air.

“In addition, forced air heating in our house tends to dry out the mucous membrane from the nose and throat, and the moisture and adhesion in our nose and throat are actually bugs. It is the first defensive line between the viruses.

He added that if your nose dries, especially while you are sleeping at night, it will be easier for the virus to enter our body.

Let's take a look at four large viruses distributed in Canada.

influenza, Generally known as influenzaIt is a very infected virus infection that affects the respiratory system such as the nose, throat, and lungs. It is mainly caused by influenza virus, A and B, According to the Ministry of Health of Health。

Symptoms include fever, cough, chills, fatigue, headache, sore throat, anorexia, and nose congestion.

The latest data of the Canadian Public Health Bureau (PHAC), which covers the week from January 18 to January 24, indicates that the number of influenza is increasing. PHAC said that there was a total of 5,162 influenza from the 37,997 test, which represents a positive rate of 13.6 % from that week.

Despite the increase in cases, Phac added that the number of influenza that was confirmed to be “generally stable” in the past three weeks.

Among the reported cases, people over 65 are the highest percentage of weekly detections.

RSV is a common respiratory virus that affects the lungs and airways. It is especially known for causing infection Young childrenElderly and people with weak immune systems, The Ministry of Health of Health said。

For most healthy people, RSV may only show mild cold symptoms, but it can lead to more serious breathing issues for higher -risk groups.

Mild symptoms include a runny nose, cough, sneezing, mild fever, and sore throat. If it is more serious, it can cause the wheezing around the lips and fingers, rapid breathing, shortness of breath, and bluish colors.

The latest data of PHAC, which covers the week from January 18 to January 24, has a total of 3,040 detection of RSV from 35,016 tests, indicating a positive rate of 8.7 %.

People between 65 and 84 have reported that the percentage of weekly detection is the highest.

PHAC added that the overall rate of RSV cases is stable.

COVID-19 is another respiratory disease, but is caused by the SARS-COV-2 virus. In this winter season, the COVID-19 stock, which is dominated in Canada, is K.P3, an Omicron strain.

Usually included in the symptoms According to PHAC, fever, cough, fatigue, loss of taste, sore throat, headache, muscle pain, vomiting, blood, or runny nose.

PHAC's latest data, which covers the week from January 18 to January 24, indicates that the ratio of COVID-19 tests has decreased by 8.3 %.

“The number of tests confirmed by the COVID-19 reported by the participating states and territory has been decreasing in general over the past four weeks,” PHAC stated.

Norovirus It is a very infectious virus that causes gastroenteritis, stomach and intestinal inflammation. It is often called gastric flu, but has nothing to do with influenza.

Symptoms include nausea, vomiting, diarrhea, stomach cramps, fatigue, low bad fever, chills, and headaches.

Unlike COVID-19, influenza, and RSV, Canada has not announced the number of reports of norovirus every week.

“Unfortunately, there is no real -time report in Canada, but there have been many reports of viral gastroenteritis over the past few weeks, so we have experienced many of them,” said Miller. 。

“The virus is usually a very troublesome 24 -hour bug. They torn classrooms, workplaces, and families, and are stressed on the piping system, but they do not cause much hospitalization.”

How to manage the symptoms of highly infectious norovirus

However, the mirror emphasized that norovirus's main concerns were dehydrated, and it was particularly important to hydrate well.

last monthPHAC's spare data has shown that norovirus infections have been reported nationwide at a higher rate than in 2019 to 2023 than the average five -year average.

Ontario Public Health Officer Recently confirmed Norovirus was detected in a group of 190 people at Guerf University, which reported on gastroenteritis last week.

Miller said that using COVID-19 can quickly get used to reliable home tests and quickly confirm whether they are infected.

However, in reality, most people have a common respiratory infection diagnostic test for common respiratory infections, so that the diagnostic test for general respiratory infections is rarely used. That's (at home, taking plenty of liquids and sleep).

“Viruses such as RSV, influenza, and COVID-19 usually have some kind of respiratory symptoms such as cough, sneezing, and runny nose, along with cough, sneezing, cold and cold.” I did.

“These are almost impossible for average people to distinguish between them, but the fact that we, especially the influenza, is more serious about fever, chills, and lethargic than we think of a cold. He tends to cause. “

It can be difficult to distinguish respiratory infections, but norovirus is often a bit clear.

“In the case of norovirus, the major differentiation factor is that it is almost always characterized by very severe gastrointestinal symptoms. Very severe acute diarrhea, nausea, and sometimes vomiting. These symptoms are very common in respiratory viruses. Not, “Miller said.

Regarding the treatment of these viruses, he recommended using commercially available rescue to manage symptoms and discomfort, then rested well and maintained hydration.

“If you get sick, it's clearly important to seek medical care,” he added.

Miller emphasized that the best protection against these viruses was vaccinated.

Vaccine impact Even at this time, it is still available, so it's not too late. There is even more COVID-19 vaccineAn RSV vaccine for the elderly And the pregnant mother, and Antibody treatment For newborns protect from RSV.

Currently, there is no norovirus vaccine, You may be on the way immediately。

The US pharmaceutical company, Moderna, is developing a norovirus MRNA -based vaccine and plans to submit a marketing application to US Health Regulatory Authorities in 2026.

The mirror also emphasized that the appropriate hand washing and staying at home in the case of illness are important defense against viruses.

Handsanitizers have been working well against influenza and Cobid 19, but the mirror warns that norovirus is very infectious and may last in the environment.

Unfortunately, hand canitizers are not effective in killing them.

“The virus that causes norovirus spreads on the surface and can stay there for a very long time. Hand -sani tizers are almost useless in noroviruses, so the conventional hand washing is much better,” he said. 。

“Hand washing is the purpose of actually removing the virus from the hand. Therefore, if it is available, it must always be given priority over hand cleaning agents.”
