Global Times: Many viruses are seasonal, and flu and cold viruses tend to peak in winter and then disappear as the weather warms. will
the new coronavirus and its new coronapneumonia ("COVID-19") follow a similar pattern? Some experts believe that the new coronavirus may have seasonal characteristics. "Given the way it spreads, coronaviruses are often associated with winter," said Elizabeth McGraw, director of the Center for Infectious Disease Dynamics at Pennsylvania State University in
.
" McGraw believes that people may gather more indoors during the winter months, increasing the risk of exposure to infections.
McGraw also mentioned the spread of the virus.
virus is spread through droplets, which are released when an infected person coughs or sneezes.
"What we know is that when the air is cold and dry, they (droplets) are more likely to stay floating.
when the air is wet and warm, it falls to the ground faster, which makes it more difficult to spread. "However, not every virus follows this pattern, such as the mersinsyndrome (MERS) virus, " says Amhesh Adarja, a senior fellow at the Center for Health and Safety at Johns Hopkins Bloomberg School of Public Health in the United States and an infectious disease expert.
", adarja says, "COVID-19" seems more like a seasonal cold.
in fact, up to a third of the common colds are caused by coronaviruses. "Basically, we've seen human-borne transmission in China, so in that sense, it really acts like a common cold caused by a coronavirus,"
. "For that reason, Adarja says, "I do think seasonality will work,"
.
with the outbreak, we're going to have spring and summer, and I do think we're going to see a decrease in cases. As a result, the virus may begin to disappear as China and other northern hemisphere countries enter the spring, the
.
, however, Adarja also cautioned that the southern hemisphere is entering autumn and winter, "so we may see an increase in the spread of the virus in parts of the southern hemisphere," such as in Australia, which is similar to the annual flu situation.
, however, some experts believe it is too early to draw conclusions, triggering the "COVID-19" of the new coronavirus has seasonal characteristics need to be further observed. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health, said
it makes sense to assume that cases will gradually disappear in the spring. "We hope that when the climate warms, it (cases) will decrease a bit,"
said.
, however, Fauci also warned, "However, we don't know much about this (new) coronavirus, and we don't have a lot of historical information."
" Nancy Messionier of the U.S. Centers for Disease Control and Prevention expressed a similar view when it comes to rising temperatures. "I think it's too early to say, " she said in an interview on the 12th, "and the virus has been in people's view for less than a year."
reported that given the uncertainty, U.S. public health officials believe they must plan for unexpected situations.
"By April and May, when the temperature rises, the virus becomes inactive and gradually disappears.
", "Why is there still an outbreak in Hainan Province?" "Recently, netizens have been arguing about the issue.
Changjiang Daily reporter interviewed Li Yan, an expert in virology and professor at Tongji Medical College of Huazhong University of Science and Technology. Professor liYan,
, said, "I have heard this statement, said that the temperature rise of the new coronavirus will disappear on its own, in fact, this is based on the development of SARS disease in that year, the new coronavirus was found less than a month, the research on this virus has just been carried out, the virus will not be because of the temperature rise inactivity, the scientific has not been conclusive."
" recently, the network also rumored that has been cured patients discharged from the hospital, may carry a small amount of virus, will continue to infect 1-3 people around, should be cured out of the patient isolation again 10-14 days.
to address this issue, Li Yan said: "Patients discharged from the hospital have strict standards, including clinical symptoms disappeared, two consecutive nucleic acid tests negative and so on."
on the current epidemiological observation, the longest incubation period of the virus is about 14 days, in addition to clinical testing also involves sensitivity, accuracy.
even if clinical discharge standards have been met, it is best to self-isolation for a period of time for safety reasons.
", Professor Li Yan and his team are currently working on drug research and development for the new coronavirus.
question and answer 1, the new coronavirus is afraid of heat or cold? The virus itself cannot complete its metabolism, nor reproduces itself, and needs to be parasitically done in other cells.
it can be moderately stable in a suitable maintenance fluid of 4 degrees C and can be stored for several years at -60 degrees C.
new coronavirus is heat sensitive to heat, with high temperatures above 56 degrees C and lasting for 30 minutes, which can effectively inactivate the virus.
Question and Answer 2, what is the difference between the spread of the virus in the south and the north? The virus slowly becomes inactive over time, inactivates slowly at low temperatures and is faster at 30 degrees C.
temperature mainly affects the survival of the virus, but it does not affect its ability to transmit.
, whether southerners or northerners, should pay attention to their own protection, to avoid virus infection.
Q and A 3, can turn on air-conditioning heating to kill the virus? The study found that reaching a certain high temperature (56 degrees C or more) and a certain amount of time (30 minutes) can effectively inactivate the new coronavirus.
but usually with air conditioning heating to raise the ambient temperature, still far from this temperature.
Q and A 4, what are the correct ways to disinfect high temperature? Towels as much as possible one day wash, bed sheets, quilts and clothing frequently change, when conditions, drying at high temperature.
water cups, teacups, tableware, etc. should be disinfected at any time after use, can be used disinfection cabinet or boiling water for 15 minutes disinfection, disinfection with flowing water rinse.
food is thoroughly cooked before eating, avoid eating raw and undercooked animal products, including eggs, milk, meat.
it should be noted that hot springs, saunas and other ways to eliminate the virus has no effect.
virus in the human memory activity is stronger, and the body body temperature is usually maintained at about 37 degrees C, even if sauna, hot spring and other environmental temperature of more than 56 degrees C, also can not affect the body's temperature environment, can not achieve the purpose of killing the virus.
, cross-infection is more likely in public places such as saunas and hot springs.
Question and Answer 5, in addition to fear of heat, virus is also afraid of what? In addition to high temperature elimination of the virus, ether, 75% ethanol, chlorine disinfectant, peroxyacetic acid and chloroform and other fat solvents can effectively inactivate the virus, daily life can pay attention to the following points: fear of air circulation someone room daily window ventilation 2 times, each 30 minutes.
don't refuse to open windows in pursuit of room temperature.
afraid of UV light can be used in no-person room once a day, each time more than 1 hour.
afraid of alcohol disinfectant flow underwater hand sanitizer or soap hand washing can be, if necessary, the use of alcohol, isopropyl alcohol, washing of tetelol solution, iodine volt and other disinfectants for scrubbing.
afraid of chlorine disinfectant using 1000 mg / liter chlorine-containing disinfectant or peroxyacetic acid, hydrogen peroxide paper towel thoroughly wipe disinfection, 2 times a day.
