BOTELELE BJA BOPHELO BJA TWATŠI YA CORONA

Dipego tša kgauswi tšeo di laeditšego go hlatloga ga palo ya batho bao ba fetetšwego ke twatši ya corona, go ya ka ditsebi, di laetša gore twatši ye e ka ba e phatlalatšwa ke batho bao le go tseba gore ba fetetšwe ke twatši ba sa tsebego.

BOTELELE BJA BOPHELO BJA TWATŠI YA CORONA

Batho ba ba ya godimo le tlase fao ba kopanago le batho ba bantši ntle le go lemoga gore ba fetetšwe. Ba re fao ba itemogago ka dika goba ba lemogwago ka morago ga diteko, ya ba ba šetše ba feteditše batho ba bantši. Karolo ya bothata bjo e dirwa ke gore twatši ye e phela nako e telele. Go thwe twatši ye e kgona go phela go thoma ka diiri tše tloga go diiri tše tharo (3) go iša go matšatši a šupago (7).

Twatši ye e phatlalatšwa ka mokgwa wa marotholotšana a mare ao thantshogago ge motho a gohlola goba a ethimola. Phetetšo e hlolega ge marotholotšana a a ka wela ka ganong, mahlong goba ka dinkong tša batho bao ba lego kgauswi. Gape motho a ka fetelwa ke twatši ka go kgwatha selo goba felo fao go nago le twatši ke moka a swara molomo, mahlo goba nko. Gore na twatši e phela nako e kaakang, go laolwa ke phišo, monola goba mohuta wa selo seo e wetšego godimo ga sona.

Bafatišiši (researchers) ba humane gore godimo ga pampiri ya go gatiša goba thišu, twatši e nyamelela mo nakong ya diiri tše tharo (3). Go tšea matšatši a mabedi gore twatši e nyamelele mo godimo ga boya le mašela. Twatši e nyamelela ka morago ga matšatši a mane godimo ga galase le tšhelete ya pampiri. Fao twatši e humanwego e phela nako e telele go fetišiša ya matšatši a šupago (7), ke godimo ga tšhipi ya go se ruse (stainless steel) le polasetiki.

Magareng ga tše dingwe, diphatišišo tše di laetša gore go bonolo go phatlalatša twatši ye ntle le go lemoga. Go rena ba go adimana goba go šielana diaparo, go bonolo go fetelwa ke twatši yeo e lego godimo ga diaparo yeo e ka phelago go iša go matšatši a mabedi. Go gohlolela goba go ethimolela godimo ga tafola ya dijo, sinki ya go hlatswa dibjana ga motho yo a fetetšwego ke twatši, go ka thuša go phatlalatša ditwatši go bao ba swarago tafola goba sinki. Ya go tšhoša ke ye ya gore twatši e ka fetša matšatši a mane godimo ga tšhelete ya pampiri. Matšatši a mane (4) godimo ga tšhelete ya pampiri? Hei, gape yeo ya tšhelete ke bothata! Ge twatši ye e phela matšatši a go iša go a šupago godimo ga polasetiki, go ya go reng ka rena re gelelago meetse ka metomo ya dipolasetiki mola re šielana metomo yeo?

The researchers also compared the new coronavirus' life span on surfaces with that of the SARS coronavirus. In a 70-degree Fahrenheit (21 degree Celsius) room at 40% relative humidity, they found that both coronaviruses lived the longest on stainless steel and polypropylene, a type of plastic used in everything from food-storage containers to toys. Both viruses lasted up to three days on plastic, and the new coronavirus lasted up to three days on steel.

On cardboard, however, the new coronavirus lasted three times longer than SARS did: 24 hours, compared with eight hours.

Temperature and humidity play a role in how long the virus survives

Some coronaviruses, including this new one, have a viral envelope: a fat layer that protects viral particles when they travel from person to person in the air. That sheath can dry out, however, killing the virus. Temperature and humidity affect that process.

One recent study found that an 18-degree Fahrenheit (77 degrees Celsius) jump, from 68 degrees (20 degrees) to 86 degrees (30 degree), decreased how long SARS lasted on steel surfaces by at least half.

The new Lancet study found a similar link between the virus' lifespan and the surrounding temperature. At 4 degrees Celsius (39 degrees Fahrenheit), the virus lasted up to two weeks in a test tube. When the temperature was turned up to 37 degrees Celsius (99 degrees Fahrenheit), its lifespan dropped to one day.

Some research has also suggested that increases in relative humidity reduce how readily the virus can spread between people.

You're unlikely to get the coronavirus from your mail

Even though the coronavirus can survive for a day on cardboard, it's unlikely that anyone would contract it after touching a box that arrives in the mail.

That's because shipping conditions make it difficult for the coronavirus to survive.

"Viruses are likely to only live a few hours to a few days under the sort of conditions we expose packages to, including shifts in temperature and humidity," Rachel Graham, an epidemiologist at the University of North Carolina, previously told Business Insider.

The Centers for Disease Control and Prevention says "there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures."

If you're concerned about your packages, though, Graham suggests using surface disinfectants like Lysol or bleach. These can kill viral particles within 15 seconds, but if you want to be extra careful, you can wait five to six minutes, she said.

But the precaution is likely unnecessary.

"If we had transmission via packages, we would have seen immediate global spread out of China early in the outbreak," Elizabeth McGraw, the director of the Center for Infectious Disease Dynamics at Pennsylvania State University, previously told Business Insider.

"We did not see that, and therefore I think the risk is incredibly low," she added.
