The flu virus can survive on surfaces for a few minutes to several days, depending on the type of surface and other factors such as temperature and humidity. Non-porous surfaces like plastic, stainless steel, glass, and countertops are more conducive to the flu virus's survival, with some sources stating that they can harbour the virus for up to 48 hours. Porous materials like fabric, paper, and wood reduce the survival time of the flu virus to a few hours or less.

What You'll Learn
Flu viruses can survive on plastic for up to 48 hours
Frequently touched surfaces such as metal doorknobs, sink faucets, and plastic toys are common objects where the flu virus can be found. During the winter respiratory virus season, public touchpoints, such as a grocery checkout keypad or the handlebars on a public bus, are also likely to harbor flu germs.
The length of time a virus remains infectious on a surface depends on factors such as temperature, humidity, surface type, and the virus itself. Viruses spread on surfaces through respiratory droplets, which can settle on surfaces and cause infections when a person touches them and then touches their face.
To prevent the flu, it is important to practice good hand hygiene and cover your mouth and nose when you cough or sneeze. Regularly washing your hands with soap and water for at least 20 seconds is essential. If soap and water are not available, use an alcohol-based hand sanitizer. Avoid touching your face, especially your mouth, nose, and eyes, as these are entry points for the flu virus.

Flu viruses can be transmitted by touching contaminated surfaces
Flu viruses can survive on hard, nonporous surfaces like stainless steel and plastic for up to 48 hours. However, the survival time can vary depending on the environment and the number of viral particles present. For example, a 2011 study found that the H1N1 flu virus could be recovered from various surfaces for up to 48 hours, but most of it was gone after nine hours.
Frequently touched surfaces such as metal doorknobs, sink faucets, countertops, plastic toys, and computer keyboards are common objects that can harbor the influenza virus. During the flu season, public touchpoints, such as grocery checkout keypads or bus handrails, are also likely to be contaminated with flu germs.
To protect yourself from surface transmission of the flu, it is important to practice good hand hygiene. Wash your hands frequently with soap and warm water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer. Avoid touching your face, especially your mouth, nose, and eyes, as these are entry points for the flu virus. Regularly disinfect commonly touched surfaces and follow product instructions for effective disinfection.

Flu prevention measures include practising good hand hygiene
Flu viruses can survive on plastic and other nonporous surfaces for up to 48 hours. They can also survive on porous surfaces, but for much shorter periods. This means that flu prevention measures are essential, and practising good hand hygiene is one of the most important habits to cultivate.
Good hand hygiene is a well-known and effective way to prevent the spread of infectious diseases, including the flu. It is a simple yet powerful tool that can significantly reduce the risk of getting sick and spreading illness to others. The flu spreads primarily through respiratory droplets when an infected person coughs, sneezes, or talks. These droplets can land on surfaces, and you can catch the flu by touching contaminated objects and then touching your face. Therefore, practising good hand hygiene is crucial to breaking this chain of infection.
To practise good hand hygiene, it is recommended to wash your hands frequently with soap and warm water for at least 20 seconds. This simple act of handwashing can effectively remove the flu virus from your hands. If soap and water are not available, using an alcohol-based hand sanitiser is a good alternative. Alcohol-based sanitisers, whether foam, gel, or wipes, have been shown to significantly reduce viruses on hands and prevent their transfer to commonly touched surfaces.
In addition to handwashing and sanitising, there are other measures to practise good hand hygiene. Avoid touching your face, especially your mouth, nose, and eyes, as these are entry points for the flu virus. If you need to cough or sneeze, cover your mouth and nose with a tissue or use the inside of your elbow. Be sure to throw the tissue away immediately. These measures may seem simple, but they are highly effective in preventing the spread of the flu and other respiratory illnesses.
While the effectiveness of hand hygiene in preventing flu transmission in community settings has been debated, with some studies showing significant results and others not, it is still a recommended practice. When combined with other interventions, such as wearing facemasks, hand hygiene can be even more effective in reducing the risk of influenza. Therefore, it is advisable to maintain good hand hygiene practices, especially during flu season, to protect yourself and others from the illness.

Flu viruses are more likely to remain infectious on hard surfaces
The flu spreads primarily through respiratory droplets that become airborne when an infected person coughs, sneezes, or talks. These droplets can then land on surfaces, and a person can become infected by touching these contaminated surfaces and then touching their mouth, nose, or eyes.
Frequently touched surfaces such as metal doorknobs, sink faucets, plastic toys, countertops, and computer keyboards are common objects that can harbor the influenza virus. During the winter respiratory virus season, public touchpoints such as grocery checkout keypads or the handlebars on a public bus are also likely to be contaminated with flu germs.
To prevent the spread of the flu, it is important to practice good hand hygiene by washing your hands frequently with soap and warm water for at least 20 seconds. If soap and water are not available, an alcohol-based hand sanitizer can be used. Avoiding touching your face is also crucial, as the mouth, nose, and eyes are entry points for the flu virus. Regularly disinfecting commonly touched surfaces can help reduce the risk of transmission.

The flu vaccine helps protect against common flu strains
The flu is a highly contagious illness that can be transmitted through respiratory droplets when an infected person coughs, sneezes, or talks. These droplets can land on surfaces, such as plastic, and be transmitted to others when they touch their mouth, nose, or eyes. While hand hygiene and surface disinfection are important preventive measures, the flu vaccine remains the most effective way to protect against common flu strains.
The flu vaccine, also known as the influenza vaccine, is designed to protect against the most common seasonal flu strains. While it is not 100% effective, it significantly reduces the risk of infection and can lessen the severity of symptoms if one does contract the flu. It is recommended that most people get vaccinated annually, as the flu virus can mutate and new strains can emerge each year.
The flu vaccine is typically administered via injection or nasal spray and takes about two weeks to start providing protection. It is generally well-tolerated, with common side effects such as redness, soreness, and swelling at the injection site, which usually resolve within a day or two. It is important to note that one cannot get the flu from the vaccine itself, and it does not protect against colds or other illnesses.
By getting vaccinated, individuals can lower their chances of contracting the flu and reduce the potential impact of the illness. This is particularly important during flu season, which typically lasts from October through May, as the vaccine can provide protection throughout this high-risk period. The flu vaccine is widely available and can be obtained from clinics, pharmacies, and doctor's offices.
In addition to vaccination, maintaining good hand hygiene and disinfecting commonly touched surfaces can further reduce the risk of flu transmission. These preventive measures, combined with the protection offered by the flu vaccine, can help individuals stay healthy and lower their chances of contracting or spreading the flu during the flu season.
