Virus protection programs evaluation

The emergence of pH1N1 in provided an opportunity to evaluate hospital preparedness for a widespread novel influenza virus where, in the absence of a vaccine or knowledge about its health consequences, the use of N95 filtering facepiece respirators or equivalent had been widely recommended by public health officials as a minimum level of respiratory protection for health care workers performing patient care.

Transmission of pH1N1 was documented among health care workers who treated the initial cases identified in California and associated with inadequate use of personal protective equipment. This onsite evaluation assessed respiratory protection programs and practices in a randomly selected set of hospitals several months after pH1N1 had spread throughout California, public health guidance on infection control measures had been widely disseminated, and a new state OSHA standard on ATDs had become effective.

Responses from unit and hospital managers indicated a high level of knowledge of this policy Health care workers from those units overwhelming In general, the basic elements required with respirator use eg, medical clearance, fit testing, and employee training were in place in all hospitals, as demonstrated by consistent responses across health care workers, unit managers, and hospital managers.

Because onsite evaluation visits were conducted in January-February , we are unable to report on the extent of N95 respirator readiness in these facilities at the start of the pandemic. We had difficulty drawing conclusions about how health care workers know when to wear a respirator, because multiple responses to this question were permitted. Signage on patient doors, information from coworkers and shift reports, and the health care worker's patient assessment were common responses.

Future investigations could look more closely at how hospital respirator policies address this topic, particularly for the earliest health care worker—patient contacts in the hospital, before diagnosis, and for nonclinical staff who may not be included in communications about suspected or confirmed disease status.

The New York City hospital study cited earlier, which identified almost 5 unprotected health care worker exposures for each patient with pH1N1 infection who presented with influenza-like illness, highlighted the need to better understand how to more effectively implement screening protocols as well as to achieve adherence to respirator use requirements. In the limited number of observations of respirator users, we did not observe health care workers failing to don a respirator when appropriate; however, frequently identified problems were failure to perform user seal checks, touching the outside of the respirator during doffing, and failure to perform hand hygiene after doffing.

Further training may be warranted in these facilities on how to properly don and doff respirators, as well as how to conduct user seal checks which should be spelled out in the manufacturers' instructions. These deficiencies in proper respirator use are significant, as they may result in a failure of the respirator to provide its intended level of protection. Review of written respiratory protection programs revealed instances where written procedures for 1 or more program elements were lacking or incomplete.

Of the 16 hospitals, only 1 had a program that was considered to be complete, and 1 hospital failed to provide a written program. Achieving an effective level of protection from respirator use relies on having comprehensive written procedures for all of the required elements, implementing those procedures, regularly evaluating the implementation of each element with respirator user input , and making necessary improvements.

Such an effort is required under the OSHA respiratory protection standard for any workplace where respirators are used. The most frequently missing program element in the hospitals' written RPPs was program evaluation, followed by the designation of a program administrator.

These results suggest that, although hospitals have made substantial progress in implementing the use of respiratory protection, it may be necessary to assign clearer responsibility for overall oversight of the program. Conducting periodic program evaluation, including observations of health care workers using respirators and soliciting input from respirator users, should be broadly implemented.

Other areas for improvement of written programs include delineating required recordkeeping procedures, and specifically how fit testing and training are conducted. We are not aware of any other published assessments of written hospital respiratory protection programs. Given California's specific OSHA requirement for the use of respiratory protection by health care workers in close contact with a patient with suspected or confirmed pH1N1 infection, we were aware of hospitals' concerns regarding the potential for respirator shortages.

Our results provide some insight on how hospitals planned for a potential shortage, most commonly through having employees reuse respirators and store them in a paper bag between uses. Half of interviewed hospital managers reported experiencing a shortage of respirators; they cited increased demand due to higher patient loads and supplier inability to fill orders as the key reasons for a shortage.

Those facilities that did not experience a shortage stated that stockpiling respirators helped them maintain adequate supply levels. Due to respirator supply issues, some hospitals were forced to use alternate respirator brands or models, and some managers acknowledged an inability to fit test all employees with the new respirator before use. Several limitations should be taken into consideration when generalizing the results of this public health evaluation.

First, California was in a unique position regarding pH1N1 because the first cases occurred here, and California enacted the nation's first occupational standard for aerosol transmissible diseases in August during the peak of the pandemic. Hospitals in California may have been faster to mobilize respirator use because they had been preparing to meet the new standard.

Because our evaluations were conducted later in the pandemic, hospitals may have had earlier deficiencies in respirator use that we could not have documented. Another consequence of the timing of our evaluation influenza activity in California had moved from widespread to sporadic by early was that some hospital units no longer had any patients on airborne precautions, seriously limiting the number of respirator use observations we could conduct. Therefore, our results and conclusions based on interview data assess knowledge and intended practices, rather than observed practices.

Our sample of 16 facilities was small, comprising 5. Hospitals that declined participation 4 out of 20 invited may have been less successful at implementing respirator use. Although we obtained a sample that was generally representative in terms of size, rural versus nonrural, and type of ownership, generalizing the findings to all facilities in the state should be done with caution.

This small sample size precluded analysis of the data by hospital characteristics. Finally, our aim was to evaluate a sample of California hospital RPPs and health care worker respiratory protection practices during a novel pandemic, and the findings are likely not applicable to seasonal influenza or other ATDs.

Studies conducted during pH1N1 documented transmission to health care workers in both inpatient and outpatient environments 14 , 17 , 20 as well as unprotected exposures. The IOM has made numerous recommendations regarding the role of respiratory protection in preventing the transmission of pandemic influenza and other viral respiratory diseases to health care workers, and continues to track the nation's progress in this important area of occupational health and safety. We found that California hospitals evaluated during pH1N1 were able to implement many of the required elements of respiratory protection programs.

However, several deficiencies were commonly noted. To provide a comprehensive occupational infection control program, hospitals should ensure that they have a written respiratory protection program, fully implement programs and procedures, and conduct periodic program evaluation to ensure the effectiveness of respirator use for health care worker protection.

Increased accessibility of information and resources tailored for hospital respirator program administrators may be helpful in this regard.

Methods Onsite evaluation of 16 hospitals consisted of interviews with managers and health care workers about RPPs and practices, review of written RPPs, and limited observations of personnel using respirators.

The next tier product, Trend Micro Internet Security, throws in some interesting extras including parental controls and social media protection tools. Whereas most updates on this list are fairly superficial, Avast ripped everything up and started again for its latest release - introducing Avast One.

Avast One takes the firm's trusted free antivirus now known as Avast One Essential and builds on it with extra features. Whether you choose to go free or upgrade, the software is really in favor with the independent testing labs at the moment, ranking towards the top of the pile in real-world malware tests and anti-phishing tasks. You also benefit from a simple firewall, data breach scanning to warn you if your online accounts are breached, and apps for Windows, Mac, Android and iOS.

So why bother paying for Avast One? You'd have to really want one of those specific add-ons to want to part with your cash, otherwise we'd suggest going for a more fully featured internet security suite or just sticking with the free Essential download. We saw a lot more thought pieces coming out in suggesting that the time was at an end to pay for your antivirus software.

And while we generally disagree with that notion, Microsoft Defender is probably the best argument in its favor. That's because if you're a Windows user, there's a perfectly capable virus protection already sitting within your operating system.

Microsoft Defender is a solid product that gives capable mid-range protection - mostly without users ever even knowing it's there. Defender has a dashboard, its own scan options and so on, but you'll never even see them unless you go looking. In the testing from independent lab AV-Comparatives, Defender ranked pretty much slap bang in the middle of the 17 tested providers. That means it's better at protecting your PC than even some of paid-for software out there.

Outside of pure virus protection, it features lots of bonus features such as multi-layered anti-ransomware, firewall, webcam and privacy protection, web filtering, parental controls and backup. So what's stopping you from forgetting the rest and simply getting Defender up and running? Well, those features mentioned above are all pretty basic and aren't up the standard of those offered by most of the security suites above. And it probably goes without saying that Defender is only available on Windows PCs - forget protecting your Mac or smartphone - and some features only play nice if you use Edge as your browser.

In truth, Avira is probably best known for its Avira Free antivirus option which is among the best out there - see further down this page , but its premium packages should not be sniffed at — especially when you consider the incredible price you can now pay for its Antivirus Pro package.

The interface is smart and the various features — including the free but limited to 1GB monthly VPN — are now better integrated within the UI overall. The caveat here is that the ratings of the antivirus engine from independent test labs are only middling at best — but the app does provide a decent enough level of protection. Upgrading to the Internet Security or Prime plan adds further features like a full password manager, and the Pro version of Software Updater which provides automatic updates for your apps , plus Prime gives you the unlimited usage version of the VPN and mobile app support.

A real bargain. McAfee takes an interesting approach with its security range, as all the offerings are variants of its core Total Protection product, with the main difference being more devices are supported at higher tiers. McAfee Total Protection Single Device is the entry-level antivirus product, and as the name suggests, it covers one device.

There are also a ton of features on offer, particularly for a baseline product, and even if not all of them are of the highest quality, you get a lot for your money. That includes an intelligent firewall, an integrated TunnelBear -powered VPN with unlimited data, a quality spam filter, secure file vault, and some PC speed-up options.

The main stumbling block here is that the antivirus engine itself is not the best out there — although some results from independent test labs come out better than others — but this has to be something of a concern. Further up the Webroot range, SecureAnywhere Internet Security Plus expands coverage from Windows and Mac PCs to mobile devices, also providing a password manager courtesy of LastPass and covering up to five devices rather than three.

And at the top of the tree is Internet Security Complete which introduces an automatic backup tool with 25GB of secure cloud storage and additional online privacy features. SecureAnywhere AntiVirus gives you everything you need, really, although Internet Security Plus is our top pick for the most rounded package. Sophos Home Premium covers up to an impressive 10 devices Windows and Mac computers.

Sophos provides capable virus protection, and worked well in passing our own anti-ransomware tests. For the antivirus software on offer — and given the 10 device ceiling — Sophos Home Premium could work out as a great value proposition for those who want to protect multiple computers.

Just note that Sophos no longer offers a long-term free version to new users. You'll see on the website you can download it for free, but that's just a trial version rather than an all-singing all-dancing free antivirus package. We've tested all of the biggest names in internet security, we've found that the very best antivirus software in is Bitdefender. It's a superb bit of software - from its entry-level Bitdefender Antivirus Plus and its cast-iron malware defenses, excellent threat detection and genuinely value-adding extra features, right up to its all-singing, all-dancing Total Security that adds an array of maintenance tools and can be used to protect your family's computers, tablets and phones.

An antivirus app sits on your device like a guard dog, watching over the entire system and sniffing out any intruders malware , or indeed anything suspicious. In short, it offers real-time defenses against viruses or other threats, which if detected are immediately dealt with, preventing them from carrying out their destructive payload.

As well as this automated protection, you can run manual virus scans whenever you wish. Think of these as the fingerprints of malware, and if something is spotted coming onto your system that has a matching fingerprint, the antivirus leaps into action, quarantining the offender. For more details on this topic, see our full breakdown of exactly how antivirus software works. The obvious answer is staring you in the face Consult our rankings in this article, which is based on our expert knowledge and thorough, continually updated reviews of the top antivirus players.

That said, obviously you also have to bear in mind your own particular needs. Or at the other end of the scale, maybe you have a large family with a ton of devices to protect, and you need a package to cater for that.

Or maybe you want a VPN service as well as antivirus, so a bundled package will save you a lot of money on subscription fees. In short, our recommendations are here as firm guidance, but modify these appropriately based on your individual requirements. For more thoughts on this, check out our article exploring how to choose the best antivirus.

The good news is that the best antivirus products are getting cheaper and cheaper to purchase, and free products are getting more and more effective A good free antivirus — like the ones we recommend on this page below — is a perfectly reasonable option for protecting your PC, with Microsoft Defender now the best we've ever seen it.

A common misconception that lingers to this day is that free antivirus protection is not adequate to deal with malware threats. The best free antivirus on the market today, Comodo Antivirus offers features more advanced than most paid antiviruses. Comodo Antivirus gives users a major advantage over not only an antivirus-free environment, but also the best paid antivirus products on the market.

Comodo's virus protection technology has proved its mettle for battling virus threats through tried-and-tested methods. Comodo antivirus also features the Default Deny Protection which, as opposed to other security software, denies access to a program if it's not in Comodo's comprehensive whitelist.
