Bacteria and germs

Bacteria and germs

Germs are microbes including bacteria, viruses, protozoa and fungi that cause illness and infections if they enter our bodies. They’re unavoidable. They’re in the food we eat and the water we drink. You can find them in soil and on plants and animals, and on just about every surface. They’re often released into the air when a person coughs or sneezes, and can survive on the hands to then be spread to other surfaces like tables and door handles.

How infection happens

Not all germs are bad. Some, like the bacteria that lives in your intestines, help to keep you healthy. It’s your immune system’s job to protect you against the germs that cause infection. Infection occurs when viruses, bacteria, or other microbes are able to breach the immune system, enter your body and begin to multiply. These germs usually enter our bodies through the mouth, eyes, nose, the nether regions, or through wounds or bites that breach the skin barrier.

Risk factors

Pathogenic microbes (i.e. an organism that causes, or can cause, disease) challenge our immune systems in many ways. They kill cells and can disrupt cell function. Our body responds by raising its temperature to inactivate the virus, secreting a chemical called interferon which blocks viruses from reproducing, or by assembling the immune system’s antibodies to target the virus. Symptoms vary depending on the organism causing the infection, but often include fever and fatigue.

病毒從何而來以及我們如何獲得它們

粒子

傳播

飛沫

感染者在呼吸、說話、咳嗽或打噴嚏時從鼻子或嘴裡流出的充滿病毒的呼吸或唾沫顆粒。它們通常會在距離驅逐它們的人 2 米範圍內掉到地上。

氣溶膠

感染者在呼吸、說話、咳嗽或打噴嚏時從口中排出的微小病毒顆粒。與液滴不同，較小的氣溶膠顆粒可以保持懸浮在空氣中。

福米特

一個被病毒顆粒覆蓋的物體，可能是因為最近有人在上面打噴嚏或咳嗽了呼吸道飛沫，或者用被細菌覆蓋的手在上面刷過。例如，玻璃可能會以這種方式變成甲酸。這些粒子可以存活幾個小時到幾天。

Protect yourself from germs

There are simple steps you can take to protect yourself from germs. Wash and sanitize your hands often. Avoid touching common areas in public places, and keep your hands away from your face. Eating well and getting enough rest helps your immune system to stay strong, and social distancing prevents the spread of contagious illnesses. Wearing a germ mask also provides flu protection and helps to reduce transmission of viruses like the common cold and COVID-19.

HOW OUR FILTRATION HELPS AGAINST GERMS

Filtration

Airinum masks use a multilayer filter technology to provide superior protection from germs. Both the Urban Air Mask 2.0 and the Lite Air Mask filter out more than 99.9% of particles down to 0.3μm in size.

Submicron dust filtering:

The bacteria masks provide a submicron dust filtering capability to protect against PM2.5 and even smaller particles.

Certification:

The technology is tested at RISE R&D center in Sweden and is certified for GB 2626-2006 KN95, similar to an industrial N95 mask or N95 respirator.
