December 30, 2019 – This year’s flu season began with a twist
Usually, starting around October and lasts till March or April, with a strain dominated during the early months and strain B appears. near the end.
But for the 2019-20 flu season, the B strain made a surprise early appearance.
B strain is less complicated than a strain and does not change, or mutate, as much as, the CDC said. It is divided into two families, Yamagata and Victoria, with most cases of Americans into Victoria. Influenza type B only affect humans and cause a pandemic, although it is seen as more dangerous for children.
Type A has many variations, mutate all the time, and is responsible for a flu pandemic. Type A can infect animals as well. It is usually transmitted from human to human through germs in the air, but the animals can pass the disease to humans, with the usual wild birds act as hosts for these viruses.
If you have the flu, you probably won ‘t be able to tell which caused tension. The symptoms may be mild little for strain B, but overall, they do not differ much: ,, cough runny or stuffy nose, body aches ,, chills, and sometimes fever. The same recommendation, and the CDC says that everyone over 6 months old should get, which will protect you against type A and type B. The drug, like, work against both strains as well, the CDC said.
experts do not know why the B strain leads way this flu season, said William Schaffner, MD, a professor of infectious diseases and preventive medicine at Vanderbilt University Medical Center in Nashville.
“This season, that whole paradigm has been turned on its head,” he said. “This year is a strange way.”
But each is slightly different flu season, he said. Last flu season, the United States has a back-to-back spikes A sports activity, with very little activity B.
Parents of small children should be cared for B strain proves more dangerous for children. A study published by the American Academy of Pediatrics showed proportionately B virus killed more children than the virus A 2010-2016.
Through the first 3 weeks of December, three children died of flu-related illnesses, all of which are associated with type B, the CDC reported on Friday. CDC’s weekly flu tracker said that on December 21, 22 children aged 16 and under have died of this flu season, with 16 deaths associated with B and six with the A strain.
Six children are known to have died in Texas from the flu, state health officials said. And the Oregonian newspaper in Portland reported that two children died in Oregon and one in Washington state.
Schaffner said he did not know why the B strain affects children so hard, but he suspected that the children had come in contact with a tension before and build up some protection. , “They have little opportunity to experience the B strain,” he
Schaffner offered two pieces of advice for parents:
Other groups that are vulnerable to strain B of the flu are people over 65; people with other diseases, such as diabetes or; and women.
“Any woman who is pregnant right now should be vaccinated,” said Schaffner. “It’s safe. The woman with flu who were pregnant were more likely to have complications of the flu.”
Another benefit is that the protection of the flu vaccine crosses the placenta to the newborn, one of the populations most vulnerable to influenza, he said
