By The Associated Press,August 29, 2018 07:01:21For more than 100 years, the medical establishment has maintained that antibiotics are needed to treat bacterial infections.

But now the evidence is mounting that antibiotics don’t do much to help.

The United States spends about $5 billion a year on the drugs and about $4 billion a month on the vaccines.

It’s estimated that about half of all people will get the flu within the next two years.

That’s the first indication that antibiotics aren’t working as well as they were intended to.

That, coupled with an outbreak of the flu last year that killed almost 2,000 people, has prompted a broad shift in thinking about how to treat the flu.

Now, experts are questioning whether the drugs’ role in treating the flu could be overstated.

“We’re going to have a very big, long-term, sustained decline in the use of antibiotics,” said Dr. Thomas Fleischmann, a professor of medicine at the University of Pittsburgh.

“The antibiotics will probably be gone.”

The decline is not just limited to the flu, but also to the common cold, pneumonia and other infectious diseases, as well.

Many experts say the decline in use of the antibiotics is not surprising because antibiotics are more often used to treat other diseases.

They are used to prevent bacteria from spreading, for example.

Fleischman, who was the chief scientist at the National Institutes of Health during the flu pandemic, said antibiotics were never meant to treat viruses.

They were developed in the 1960s to treat respiratory infections, such as tuberculosis.

In the past, Fleisch, who is now retired, was concerned that antibiotics would be used to make people sick.

That wasn’t what happened.

“There was a time when we had this view that antibiotics were very effective in controlling infection,” he said.

But the flu was a different story.

The flu is the result of a virus that spreads through a mosquito.

Most flu cases are among children younger than 6.

Fleishman said the most important thing to know about the flu is that it is transmitted by the Aedes aegypti mosquito, a species that normally lives only in tropical areas.

The Aedes is more common in colder climates and more often associated with warmer climates, so it makes sense that the virus would spread from person to person.

But what happens in the tropics doesn’t always match what happens on the ground, said Fleisch-man.

“What happens in warmer climates is that there are fewer mosquitoes,” he explained.

“So that means that there is less resistance and less resistance to the virus.

So that’s the way you get resistance.

And then in the cold, you get less resistance.”

The flu vaccine is designed to protect against the flu and prevent the spread of the virus, but that’s not what happens.

Instead, the vaccine contains a weakened version of the vaccine designed to make it more effective against the virus when it enters the body.

That weakened vaccine works best when given before a person’s body is exposed to the cold.

But that’s difficult to get when a person is cold and has no other means of preventing the virus from spreading.

And that’s when people need antibiotics, Fleishmann said.

He said that the flu vaccine has become so ineffective that the government is now looking at ways to replace it.

The U.S. has about a billion people.

About 40% of the people who get the vaccine have had flu.

About 5% of people get the shot before they get sick.

About 10% get it after they have gotten sick and the rest get the second shot.

About 3% get both shots.

The second shot works well for about 70% of cases, but about 20% of those with flu don’t get the full effect of the first shot, Fleissman said.

The Centers for Disease Control and Prevention estimates that about 12% of adults and 12% to 15% of children get the first flu shot and have the flu in the first year.

About 1 in 10 adults and 1 in 5 children get both.

The CDC estimates that more than 2 million people are infected with the flu every year.

Most people recover quickly and are then able to get the next shot.

But a small percentage have to be hospitalized.

And some people have to have their immune systems tested to find out if they are infected.

Some people may need more treatment, and they may need to be monitored for the flu for longer.

The number of flu deaths has been rising in recent years.

In January, the CDC said it was predicting an increase of about 20,000 deaths from the flu each year by 2020.

The agency said that more people died of influenza in the last week of September than in the entire month of April.

The latest figures from the CDC suggest that about 8,400 deaths occurred in the U.K. in the week ending Sept. 12.

In Canada, the number of deaths was higher, with 4
