NEW YORK — The U.S. flu season is under way, with cases surging across much of the country, health officials said Friday. 

The Centers for Disease Control and Prevention noted sharp increases in several measures, including lab tests and emergency room visits. 

“It’s been increasing at a pretty steady pace now for the past several weeks. So yeah, we are certainly in flu season now,” said the CDC’s Alicia Budd. 

Thirteen states reported high or very high levels of flu-like illness last week, about double from the week before. One is Tennessee, where a sickness spike is hitting the Nashville area, said Dr. William Schaffner, an infectious diseases expert at Vanderbilt University. 

“Flu has been increasing, but just this last week has exploded,” Schaffner said. He noted that in a local clinic that serves as an indicator of illness trends, as many as a quarter of the patients have flu symptoms. 

Louisiana is another early hot spot. 

“Just this week is really that turning point where people are out because of the flu,” said Dr. Catherine O’Neal, an infectious diseases doctor at the largest private hospital in the state, Our Lady of the Lake Regional Medical Center in Baton Rouge. “You hear parents saying, ‘I can’t come to work because of the flu’ and ‘Where can I get a flu test?’” 

There are a number of bugs that cause fever, cough, sore throat and other flu-like symptoms. One is COVID-19. Another is RSV, or respiratory syncytial virus, which is a common cause of cold-like symptoms but can be dangerous for infants and the elderly. 

The most recent CDC data show COVID-19 hospitalizations have been declining since summer. COVID-19 activity is moderate nationally, but high in the Midwest, according to CDC wastewater data. 

RSV hospitalizations started rising before flu did and now show signs of possibly leveling off, but they remain a little more common than admissions for flu. Overall, RSV activity is low nationally, but high in the South, the wastewater data show. 

The CDC called the start of flu season based on several indicators, including lab results for patients in hospitals and doctor’s offices, and the percentage of emergency department visits that had a discharge diagnosis of flu. 

No flu strain seems to be dominant, and it’s too early in the season to know how good a match the flu vaccine will be, Budd said. 

Last winter’s flu season was considered “moderate” overall, but it was long — 21 weeks — and the CDC estimated there were 28,000 flu-related deaths. It was unusually dangerous for children, with 205 pediatric deaths reported. That was the highest number ever reported for a conventional flu season. 

The long season was likely a factor, Budd said. Another factor was a lack of flu vaccinations. Among the children who died who were old enough for flu vaccinations — and for whom their vaccination status was known — 80% were not fully vaccinated, according to the CDC. 

Vaccination rates for children are even lower this year. As of Dec. 7, about 41% of adults had received a flu vaccination, similar to the rate at the same point last year. The percentage is the same for kids, but for them that’s a drop from a year ago, when 44% were vaccinated against the flu, according to CDC data. 

Vaccination rates are lower still against COVID-19, with about 21% of adults and 11% of children up to date. 

Flu experts suggest everyone get vaccinated, especially as people prepare to attend holiday gatherings where respiratory viruses can spread widely. 

“All those gatherings that are so heartwarming and fun and joyous are also an opportunity for this virus to spread person to person,” Schaffner said. “It’s not too late to get vaccinated.”

As new potential threats from Chinese hackers were identified this week, the federal government issued one of its strongest warnings to date about the need for Americans — and in particular government officials and other “highly targeted” individuals — to secure their communications against eavesdropping and interception.

The warning came as news was breaking about a Commerce Department investigation into the possibility that computer network routers manufactured by the Chinese firm TP-Link may pose a threat to the millions of U.S. businesses, households and government agencies that use them.

Also on Wednesday, Congress took long-awaited steps toward funding a program that will purge other Chinese technology from U.S. telecommunications systems. The so-called rip-and-replace program targets gear manufactured by Chinese firms Huawei and ZTE.

Too far behind

While experts said the recent actions are a step in the right direction, they warned that U.S. policymakers have been extremely slow to react to a mountain of evidence that Chinese hackers have long been targeting essential communications and infrastructure systems in the U.S.

The lack of action has persisted despite law enforcement and intelligence agencies repeatedly sounding alarms.

In January, while testifying before the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party, FBI Director Christopher Wray said, “There has been far too little public focus on the fact that [People’s Republic of China] hackers are targeting our critical infrastructure — our water treatment plants, our electrical grid, our oil and natural gas pipelines, our transportation systems. And the risk that poses to every American requires our attention now.”

A year previously, Wray had warned lawmakers on the House Appropriations Committee that his investigators were badly outnumbered.

“To give you a sense of what we’re up against, if each one of the FBI’s cyber agents and intel analysts focused exclusively on the China threat, Chinese hackers would still outnumber FBI Cyber personnel by at least 50-to-1,” Wray said.

Decades of complexity

Part of the problem, experts said, is that it is difficult for policymakers to summon the political will to make changes that could be disruptive to the lives and livelihoods of U.S. citizens in the absence of public concern about the problem.

“It still remains very, very difficult to impress upon average, typical everyday citizens the gravity of Chinese espionage, or the extent of it,” said Bill Drexel, a fellow with the Technology and National Security Program at the Center for a New American Security.

He contrasted the relatively muted public response to the recent revelation of a Chinese hacking operation known as Salt Typhoon, which compromised mobile telephone networks throughout the country, with the uproar that accompanied the far less serious appearance of a Chinese spy balloon over the U.S. mainland in 2023.

“That just goes to show this … problem where really grave issues that are intangible — that are just in cyberspace — are really hard to wrap our minds around,” Drexel told VOA.

“For four decades, we intertwined our supply chains very deeply with China, and our digital systems became more and more complex, allowing more and more compounding ways to be hacked, to be compromised,” Drexel said.

“We’ve just started to try to change course on this stuff,” he added. “But there’s so much momentum for so long on these issues, and they continue to compound in complexity, such that it’s just really hard to catch up.”

Warning ‘highly targeted’ Americans

The Cybersecurity and Infrastructure Security Agency (CISA) issued guidance on Wednesday, reporting that it “has identified cyber espionage activity by People’s Republic of China (PRC) government-affiliated threat actors targeting commercial telecommunications infrastructure.”

It continued, “This activity enabled the theft of customer call records and the compromise of private communications for a limited number of highly targeted individuals.”

The warning appeared to be related to the Salt Typhoon hack that, according to government investigators, compromised all the major mobile phone carriers in the U.S., giving the Chinese government extraordinary access to the communications among millions of Americans.

The five-page CISA document outlines steps that the agency advises all Americans, but particularly those most likely to be targeted, to take immediately.

The first is to immediately curtail use of standard mobile communications platforms, such as voice calls and Short Message Service (SMS) texting. Instead, the agency advises Americans to restrict their communications to free messaging platforms that offer end-to-end encryption, such as Signal, which support one-on-one and group chats, as well as voice and video calls. Data sent with end-to-end encryption is extremely difficult to decrypt, even if a malicious actor is able to intercept it during transmission.

Among the other advice CISA offered was to avoid using SMS messages for multifactor authentication by switching to apps that provide authenticator codes or, where possible, adopting hardware-based security keys for highly sensitive accounts. Other recommendations included the use of complex and random passwords stored in password manager software, as well as platform-specific suggestions for iPhone and Android users.

TP-Link concerns

On Wednesday, The Wall Street Journal reported, and other outlets subsequently confirmed, that the Commerce Department, as well as the Justice and Defense departments, are investigating reports that computer routers manufactured by the Shenzhen-based TP-Link are one vector of attack for Chinese hackers.

TP-Link currently dominates the market for computer routers in the U.S., with nearly two-thirds of total market share. In October, a report from Microsoft revealed that one Chinese hacking operation it identified as CovertNetwork-1658 has compromised thousands of TP-Link routers to create a network that is used by “multiple Chinese threat actors” to gain illicit access to computer networks around the world.

The Journal’s reporting also revealed that the Commerce Department is considering a ban on the sale of TP-Link routers in the U.S. next year, an action that could significantly disrupt the U.S. market for networking hardware.

Rip and replace

Congress on Wednesday took long-delayed action to address a different potential threat from China, allocating $3 billion to a program that will remove telecommunications equipment manufactured by Huawei and ZTE from rural telecommunications networks in the U.S.

Funding for the rip-and-replace program arrives years after the U.S. identified the two companies as posing a potential threat.

Beginning in the first Trump administration and continuing during Joe Biden’s time in office, the U.S. pressured allies around the world to block the installation of Huawei and ZTE 5G cellular communications equipment from their networks, in some cases threatening to stop sharing sensitive intelligence with allies that failed to comply.
