So let's clear up a few things up.

First off Hillary Clinton did not get sick in a vacuum.

The illness that sickened Hillary Clinton with pneumonia and caused her to have to be escorted away from September 11 ceremonies in New York on Sunday also struck down several members of her campaign team at Clinton headquarters in Brooklyn, PEOPLE has learned. 

 "Everyone's been sick," a campaign source tells PEOPLE. 

At the end of August, two weeks before Clinton was diagnosed with pneumonia, a debilitating bug was making the rounds among staff at her headquarters and campaign aides who travel with Clinton, a source tells PEOPLE. 

Secondly Hillary is not the first presidential candidate to campaign with pneumonia.

Hillary Clinton is not the only candidate to experience this illness. In 2004 John Kerry also developed “walking pneumonia.” 

From an email he wrote to the New York Times in 2008, “I remember on the bus in Iowa, my staff thought I’d broken a rib from coughing because my walking pneumonia was so bad.”

Do you remember how the press freaked out about Kerry's illness, and claimed that campaign was over and he needed to be replaced at the top of the ticket?

No you don't. And that it because John Kerry was a man, and Hillary is held to a completely different and unfair standard.

You can deny it if you want, but the evidence is overwhelming.

And speaking of different standards: 

For 18 months, Republican strategists, political pundits, reporters and Americans who follow them have been pursuing Hillary Clinton’s personal email habits, and no evidence of a crime has been found. But now they at least have the skills and interest to focus on a much larger and deeper email conspiracy, one involving war, lies, a private server run by the Republican Party and contempt of Congress citations—all of it still unsolved and unpunished. 

Clinton’s email habits look positively transparent when compared with the subpoena-dodging, email-hiding, private-server-using George W. Bush administration. Between 2003 and 2009, the Bush White House “lost” 22 million emails. This correspondence included millions of emails written during the darkest period in America’s recent history, when the Bush administration was ginning up support for what turned out to be a disastrous war in Iraq with false claims that the country possessed weapons of mass destruction (WMD), and, later, when it was firing U.S. attorneys for political reasons. 

Like Clinton, the Bush White House used a private email server—its was owned by the Republican National Committee. And the Bush administration failed to store its emails, as required by law, and then refused to comply with a congressional subpoena seeking some of those emails.

So was the Bush administration the focus of numerous Congressional investigations,  culminating with the former president being called to testify as to why he and his staff destroyed evidence and defied the law?

No.

Why not?

Because they are Republicans and fuck you, that's why not!

Remember Republicans do not believe in accountability unless it has to do with the Democrats. And that goes triple if their first name is "Hillary."
