2020 Flu Season
2020 Flu Season

This post has been updated.

This year’s flu season turned into so that the number of people seeking treatment in doctors’ offices and emergency rooms almost as high as the peak levels reported during the 2009-2010 swine flu pandemic, federal officials said. This has led to their word. During the week ended February 24 death of 17 children from the flu reported to federal health officials, bringing the total child deaths so far this season to at least 114 nationwide.

from the Center for Disease Control and prevention show signs that the harsh flu season is apparently leveling off. For the second week in a row, the percentage of doctor visits for fever, cough and other flu symptoms had decreased from the previous week. But the rise in secondary infections by influenza strains can cause flu activity.

“flu Data today showed activity fell significantly for the second consecutive week, which means that we peaked at the beginning of February,” CDC spokeswoman Kristen Nordlund said in a statement on March 2. “However, this is about the same levels of influenza-like-illnesses that we see at the top of last season, so there’s still a lot of flu out there.”

He added that the 2017- 2018 season as the other previous seasons dominated by a particularly virulent strain. In seasons when that strain dominant early, “we may see the end of the season lumps” of an increase in viral strains were circulating more. “

Officials say this season has been unusual since influenza slammed almost entire continental United States on the same time, and the intensity continued for several weeks in a row.

Reporter Lena H. Sun has been talking with health care providers about this flu season. Here are some answers to frequently asked questions:

Q: What happens with the flu this season

this flu season started early, and the rest of the country experienced flu activity widespread and intense. There is a very in the number of people going to see their doctor or health care provider, affecting schools and the workplace. A few weeks ago, the rate of hospitalization in California four times higher than what they were in 2014-2015; in Oregon and Minnesota, hospitalization rate double what they were back then

Q :. Is there anything particularly bad about this year’s flu strain

This season, the dominant strain as well? disgusting, H3N2, which caused the worst outbreaks of the two viruses are two types of influenza A and influenza B viruses circulating among people and is responsible for an outbreak of seasonal flu each year. Season when the H3N2 strain dominated associated with more hospitalizations, deaths of more and more diseases. They were very hard hit is very young, the elderly and people with certain chronic health conditions, experts say

As said above CDC flu expert Daniel Jernigan. “Of the viruses we hate, we hate more than any other H3N2.” This strain, which has been around for 50 years, was able to change faster to get around the human immune system from other viruses that are targeted in this year’s seasonal flu vaccine.

Since the beginning of 2018, however, the overall proportion of influenza A virus declines, and increased the proportion of influenza B virus, and that could cause a second bump in flu activity, officials said.

The CDC estimates that flu has resulted in between and 12,000 to 56,000 deaths each year in the United States since 2010.

Q:.? Is there a difference flu symptoms this season

No. flu symptoms vary from person to person. In general, people who have the flu often feel some or all of these symptoms, according to the CDC:

Most people with flu better in a few days to less than two weeks. But some people may develop caused by a viral infection of the nasal passages and throat and lungs. children, adults age 65 and older, pregnant women, and people with chronic medical conditions among groups of people at high risk of serious flu complications, may require hospitalization and sometimes resulted.

Q: How effective is the vaccine this year

CDC and doctors recommend annual flu vaccine for everyone 6 months and older as the first step and the most important in protecting against this serious disease. The body takes about two weeks to produce the full immune response. vaccinatio flun can reduce disease and prevent flu-related hospitalizations. A study last year was the first of its kind to show that the flu vaccination lowered the risk of death associated with half of children with high-risk medical conditions and nearly two-thirds of the children were healthy.

But the flu vaccine is not perfect. Even in a good year, the flu vaccine is not as good as most other vaccines. Health officials must select strains of influenza vaccine makers should target for the season months in advance, when it is difficult to know what strains may be circulating. When the flu vaccine are well matched to the circulating virus, the effectiveness, at best, about 60 percent. (Measles, by comparison, is about 97 percent effective with two doses.) In years when the flu strains circulating match the vaccine, which means the level of effectiveness that about 3 out of 5 people who get the shots are far less likely to become so sick that they require a visit to the doctor.

In general, influenza vaccines tend to work better against influenza B and influenza A (H1N1) virus and offer a lower protection against influenza A (H3N2) virus.

The CDC has shown flu vaccine in mid-season, but fell to 25 per cent against the dominant strain H3N2. Its 25 percent effectiveness rate means that one in four people getting shot reduces the risk that they become sick enough to need a doctor. The report confirms what federal health officials and experts-infection has been suspected for some time. In the relentless bad flu season like the current ones, which are dominated by the most feared flu strains, the vaccine less effective.

The CDC report found that the current vaccine is 67 percent effective against other influenza A strain, H1N1, and 42 percent effective against influenza B virus

One piece of encouraging news. in children younger than 9, it offers much greater protection against dominant strains, cutting more than half the risk of becoming so sick that they need to see a doctor

Q :. How long will this last flu season, and when will it peak

very unpredictable flu ?. The exact time and duration can vary, but influenza activity often begins to increase in October. Most of the time, influenza activity peaks between December and February, although the activity can take place until the end of May. It may be this flu season has peaked for office visits and emergency room hospital doctor has begun to decline. Experts say the season is likely to continue into mid-April, which means a few more weeks of flu activity

Q:.? What are the symptoms of flu should parents supervise their children

Patsy Stinchfield, a nurse practitioner children and senior director of infection prevention and control in Hospitals and Clinics of Minnesota children, say parents should call or take a child -children them to the doctor early if children do not drink, really lethargic, have pain in a particular place in the chest or difficulty breathing after normal activity, such as going to the top. Also, if they are getting better and suddenly deteriorated, bringing them to the hospital immediately, as this could be a sign of a secondary bacterial infection.

“These kids do not do well when taken at the end of treatment,” he

these stories about and recently showed flu how dangerous this disease can be < / p>

Q: .. Why dying so many healthy children from the flu?

vulnerability of children is of particular concern this season. As in last winter flu season, about three-quarters of children who have died are not fully vaccinated, and about half the previously healthy, officials said. The number of deaths of children may not include all cases due to the typical lag time to report non-hospital death. (Countries are not required to report the death of an adult.)

Based on current trends, the number of child deaths could exceed 148 reported during the 2014-15 season, when the vaccine resulted in a bad game overall effectiveness of 19 percent. this season’s flu vaccine is almost twice as effective as a whole, at 36 percent.

Experts say one reason that healthy children are much more vulnerable to do with how their immune system response. For some who have not received a flu vaccination, infection with flu strain previously not exposed to them can trigger their immune systems overreact. Which can cause, Widespread inflammation that ultimately fatal

Q: Some news reports have claimed the flu vaccine is expected to be only 10 percent effective this year; Is this true?

U.S. Officials often look to Australia, where the flu season starts during the summer and winter, for hints on what to expect for the flu in the United States. Influenza virus infections began to rise earlier than usual in Australia, hitting historic highs in some areas, and the interim report suggests that the effectiveness of the vaccine. The vaccine for the United States has the same composition as that used in the southern hemisphere.

But Australia vaccination only the elderly and infirm, who usually do not respond as well to vaccines. The approach makes a difference in the effectiveness of vaccines for children have a better response. CDC officials say a better predictor of the effectiveness of the vaccine for H3N2 is the effectiveness of the vaccine last season in the United States. The current vaccine containing H3N2 component of the same as last season, which is about 32 percent effective.

A new study by Canadian researchers shows the components of the H3N2 vaccine is only about 17 percent effective in preventing infection in Canada

One of the reasons the vaccine may be less effective in these strains should be done in a way that most vaccines are produced. by growing them in eggs. When the H3N2 virus is inserted into the eggs, small changes occur – more than with any other virus -. Which affect the ability of the egg-grown vaccine to target a circulating strain, which appears to be a factor in the effectiveness of vaccines

Q: Should I still get a flu shot

Yes ?. Experts say there are other types of flu that appears and is a major cause of disease. Influenza B virus, which this year also includes a vaccine, and the vaccine is more effective against influenza B than against the dominant strain H3N2. influenza B virus tends to appear later in the season. other influenza A virus, H1N1, also addressed more effectively with the vaccine, and has appeared in countries that previously had a lot of H3N2 activity. Even the most effective vaccine offers some degree of protection against serious complications. The following is to find locations that still offer flu vaccinations

Q :. What if I think I have the flu? What types of treatments are available?

The antiviral drugs such as Tamiflu can reduce symptoms and shorten the duration of illness. Most people who get the flu have mild disease and do not need antiviral drugs. But people who are very sick or people with flu-like symptoms at high risk for serious complications should be treated as soon as possible with antiviral drugs. That means people 65 and older, children, people with chronic conditions, such as diabetes, heart disease or asthma, and pregnant women and other people are more susceptible to serious flu illness.

The CDC has urged doctors not to wait for the test confirmed but to begin treatment if they suspect flu in high-risk patients with severe pain or. children and children with high-risk conditions respond best when it is given Tamiflu within the first 48 hours.

Also, if you or your child is sick, stay home from work or school to avoid spreading to other people are not suspicious, especially those who haveand are at higher risk

Q:.? What flu do to the body, and why some healthy people die

virus causes damage all by itself, but the immune response triggered, especially among the young, healthy adults, also make people sick and can cause death , After entering the body, often inhaled through the nose or mouth, influenza virus began hijacking of human cells in the nose and throat for a make copies of itself. Virus implanted in the mucous membrane in the back of the throat and upper part of the bronchial tubes. In doing so, it weakens or destroys feather-like cells in the bronchial tubes patron who pushed out bacteria and other materials, “like so many small paddle,” said William Schaffner, an infectious disease expert at Vanderbilt University.

Without protection, the bacteria – the kind that causes pneumonia – can work their way down the bronchial tubes and the lungs, causing a complication of bacterial pneumonia, he said

Influenza virus can also the trigger. large immune response, especially in adolescents and young adults with strong immune systems, that this Otherwise healthy people are basically drowning in their own immune cells and proteins, said Stinchfield in Children Minnesota. Or, as Schaffner said excessive immune response “can make your whole body metabolism awry. It’s like the army set off a bomb and kill all the good things while targeting a virus “

Q :. If someone has had the flu this season, does that mean they now have immunity against the strains they have and will not / can not get it again this season?

While the likelihood that a person will be protected from the disease caused by a virus that first made them sick, there are four different flu viruses circulating this season, according to the CDC. They advise you to take precautions to protect themselves, including vaccination if you have not received your vaccine.

A person can definitely get the flu more than once during a season. Texas mother and grandmother survived this woman 58 years his first bout of the flu,

Q: How long does the flu germs stay active

They can live on surfaces for 1- 2 days

Q :. What can I do to avoid getting sick

In addition to vaccination, the most important thing to do is prevent the spread of germs ?. Wash your hands often, soap between your fingers and do not forget your thumb, and scrub for about 20 seconds. Some, such as the Washington Post reported by my colleague Jura Koncius:

Isolate toothbrush. After the members of the household have a cold, it is best to separate them from the rest of the toothbrush package to avoid bacteria contamination. Once the person gets better, replace the toothbrush or toothbrush head with a new one.

Launder bed often. The best thing to do if someone is sick is to place them in a separate room to sleep, prevent the spread of germs and preserve your precious sleep. If this is not possible and you have to share the same bed, wash your bed linens frequently in hot water. Even helping to wash only the pillowcases every few days. The bath towels to be washed every day or two.

Clean your humidifier. Humidifier helps soothe the sinuses and nose, especially when you have a cough and chest congestion. But if you use your humidifier every day to make your patient feel better, once a day you have to empty the tank and then remove it until it was dry. Do a thorough cleaning of at least weekly, following the instructions provided for a particular model. “You do not want to breed bacteria there and spewed into the room,” Carolyn Forte, director of the Good Housekeeping Home Appliances, Cleaning Products and Textiles Lab, told The Post.

Keep remote deleted. flu sufferers whose homes and clicking through Netflix and HBO victims must remember that all the remotes that will be covered in germs. Keep a container of antibacterial wipes around so that you can clean the remote every day; cleaning lights and the door handle with them, too. Put a small waste basket in the TV room with a plastic liner for all wet tissues and used tissues, and empty once or twice a day
