Avoiding Crowded Indoor Spaces And Ventilation
The CDC recommends that crowded indoor spaces should be avoided. When indoors, increasing the rate of air change, decreasing recirculation of air and increasing the use of outdoor air can reduce transmission. The WHO recommends ventilation and air filtration in public spaces to help clear out infectious aerosols.
Exhaled respiratory particles can build-up within enclosed spaces with inadequate ventilation. The risk of COVID-19 infection increases especially in spaces where people engage in physical exertion or raise their voice as this increases exhalation of respiratory droplets. Prolonged exposure to these conditions, typically more than 15 minutes, leads to higher risk of infection.
A New Study Reveals That Covid
Researchers have said that Covid-19 that causes the novel coronavirus infection, can survive for 28 days on smooth surfaces such as stainless steel, phone screens, glass, plastic and banknotes.
Contrary to previous research that suggested Covid-19 can survive for three to seven days on smooth surfaces, the recent study by researchers at Australian agency CSIRO says that the virus can remain infectious for up to 28 days — longer than the flu virus– when kept in the dark at room temperature .
This research paper was published in the journal Virology Journal on October 7.

If Someone In Your Household Has Covid
If you live with someone who has COVID-19 or have had a guest with a positive case in your home within 24 hours, disinfect your house in addition to regular cleaning. This will kill any leftover germs and lower the chance of the virus spreading.
- Read the instructions on the disinfectant first.
- Wear gloves while disinfecting and cleaning.
- If your disinfectant doesnât have a cleaning agent, wash dirty areas with soap first, and then use the disinfectant.
- Wash your hands often for 20 seconds with soap if youâre cleaning a household with a positive COVID-19 case. Always clean your hands after wearing gloves.
- Make sure you have good ventilation while using a disinfectant.
If youâre unable to keep a separate bedroom or bathroom from the person with COVID-19, make sure they clean and disinfect shared spaces after each use. If the sick person is unable to clean, wear a mask and use gloves to clean and disinfect their area only when needed. Make sure to open windows or doors, and use fans, heating, ventilation, and air condition to get proper air circulation.
Once the person is no longer sick, itâs important to cleanse the area they stayed in. Wear a mask when you clean and disinfect. Wait as long as possible before you do this. If youâre able to wait 24 hours before you clean their area, you only need to cleanse that space, not disinfect it.
If you wait 3 days after the person in your household was sick, no extra cleaning is necessary.
I Recently Spent Time With Someone Who Tested Positive For Covid
Yes, you do. In July 2021, the CDC recommended that anyone who is fully vaccinated and comes into contact with someone who has, or is suspected of having, COVID-19 should get tested three to five days after exposure. In addition, you should wear a mask in public indoor settings for 14 days or until you receive a negative test result. If you are vaccinated, you do not need to quarantine, but you should isolate if you develop symptoms or receive a positive test result.
Previously, the CDC had said that someone who was fully vaccinated only needed to get tested after exposure if they were experiencing symptoms. The change follows new evidence regarding the Delta variant, which shows that people who are vaccinated and then get infected can spread the virus to others, perhaps to the same extent as those who are unvaccinated.
If you are not fully vaccinated, a 14-day quarantine remains the best way to avoid spreading the virus to others after you’ve been exposed to someone with COVID-19. According to CDC guidelines, you may discontinue quarantine after a minimum of 10 days if you do not have any symptoms, or after a minimum of seven days if you have a negative COVID test within 48 hours of when you plan to end quarantine.

I Am Pregnant And Plan To Eventually Breastfeed My Baby Is It Safe For Me To Get A Covid
In August 2021, the CDC gave its clearest recommendation to date that women who are pregnant, thinking about becoming pregnant, or who are breastfeeding should get vaccinated against COVID-19. The American College of Obstetrics and Gynecology and the Society for Maternal-Fetal Medicine also agree that all pregnant and breastfeeding individuals should be vaccinated. The World Health Organization recommends use of a COVID-19 vaccine in pregnant women when the benefit to an individual outweighs the potential vaccine risks. Experts, including the WHO, believe it is most likely safe to get a COVID-19 vaccine if you’re breastfeeding. Similar to any decision regarding over-the-counter medications and supplements during pregnancy, your own doctor is in the best position to advise you based on your personal health risks and preferences.
Here are some factors to consider. First, although the actual risk of severe COVID-19 illness and death among pregnant individuals is very low, it is higher when compared to nonpregnant individuals from the same age group. In addition, COVID-19 increases risk for premature birth, particularly for those with severe illness, and possibly also for other undesirable pregnancy outcomes. Transmission of the virus from mother to baby during pregnancy is possible, but it appears to be a rare event.

Should I Wear A Face Mask
The CDC continues to monitor the spread of COVID-19 and recommends wearing face masks for those who are;fully vaccinated;as well as those who are not especially when you are in areas of high viral transmission.
The CDC recommends wearing masks and maintaining physical distancing in doctors offices, hospitals or long-term-care facilities. Johns Hopkins Medicines current safety guidelines require everyone to wear masks inside our facilities, including hospitals, care centers and offices.
Face Masks And Respiratory Hygiene
The WHO and the US CDC recommend individuals wear non-medical face coverings in public settings where there is an increased risk of transmission and where social distancing measures are difficult to maintain. This recommendation is meant to reduce the spread of the disease by asymptomatic and pre-symptomatic individuals and is complementary to established preventive measures such as social distancing. Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection. But, if the mask include an exhalation valve, a wearer that is infected would transmit the virus outwards through it, despite any certification they can have. So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale. Many countries and local jurisdictions encourage or mandate the use of face masks or cloth face coverings by members of the public to limit the spread of the virus.

Explained: How Long Can Covid
Awareness is key to combating the deadly second wave of Coronavirus pandemic sweeping through the country. Here are responses to some of your questions with regard to the virus and the precautions against it:
How long does the virus survive on surfaces?;
Studies have shown that the virus can survive for up to 72 hours on plastic and stainless steel, under four hours on copper and 24 hours on cardboard. The most important aspect is that they can easily be cleaned with common household disinfectants that will kill the virus.;
Is Tocilizumab effective? When should it be recommended?
Tocilizumab can be very useful in helping patients slipping away into a critical stage. It should be used only on those who are on oxygen therapy and who do not suffer from known contra-indications.;
Another criterion that needs to be considered is the presence of severe disease . Other criteria include significantly raised inflammatory markers, non-responsiveness to steroids and absence of active bacterial/fungal/tubercular infection.
What do I do if I do not have an Oximeter?;
Keep your palm on your chest and measure your respiratory rate for one minute. It is fine if the respiratory rate is less than 24. If the respiratory rate is over 24, it is moderate. If the respiratory rate is over 30, it may be a severe disease.
Does vaccine adversely affect pregnant women?;
When should the second dose ideally be taken?;
Do taking antibiotics cure Coronavirus?;

Regular household washing machines typically only go up to about 130 degrees on their hottest setting.
The findings suggest that hospital staff should refrain from wearing their uniforms home, according to Dr. Laird, whose study has been submitted to a research journal for publication, pending peer review.
This research has reinforced my recommendation that all health-care uniforms should be washed on site at hospitals or at an industrial laundry, she said. These wash methods are regulated and nurses and health-care workers do not have to worry about potentially taking the virus home.

Can You Catch The Coronavirus From Surfaces
Although the coronavirus weakens and dies over time outside the human body, studies suggest it can live on surfaces for a few hours or up to several days, depending on the surface, temperature and other environmental factors. For instance, a small amount of the coronavirus is detectable on plastic surfaces for up to three days, on stainless steel for up to two days and up to one day on cardboard,;but its at less than 0.1% of the starting virus material.
So far, evidence suggests that the virus does not survive as well on a soft surface as it does on frequently touched hard surfaces like elevator buttons and door handles.
More research will provide information on the coronavirus and how long it lives on surfaces. In the meantime,;wash your hands thoroughly;after being in public places.

Can Humans Get The Coronavirus From Dogs Or Cats
Jason Villano, D.V.M., a veterinary expert at Johns Hopkins, says, Despite the very few reports worldwide, including here in the United States, of sick and healthy domestic animals, including pets, testing positive for SARS-CoV-2, the virus that causes COVID-19, there is little evidence at this time that such animals are easily infected with the virus under normal conditions, or could transmit it.
If COVID-19 cases are increasing in your area, experts recommend keeping pets indoors or avoiding socialization of pets with other animals, and maintaining good hygiene when handling or caring for your animals.
- Wash your hands before and after interacting with animals.
- Dont kiss your pets or let them lick you or share your food.
- Walk dogs on a leash.;Do not allow pets to interact with people or other animals outside the household.
- People who are ill with COVID-19;should let someone else take care of their animals. If this isnt possible, patients should wear a mask while looking after their pet, and wash their hands before and after.

What About The Air
Hong Kongs Covid-19 burden more than 5,400 confirmed cases and 108 deaths is relatively low for any city. Yet some experts say it has been slow to address the risks of indoor aerosol transmission.
Early on, officials required Hong Kong restaurants to install dividers between tables the same sort of flimsy, and essentially useless, protection used at the U.S. vice-presidential debate in October.
But as the Hong Kong authorities have gradually eased restrictions on indoor gatherings, including allowing wedding parties of up to 50 people, there is a fear of potentially new outbreaks indoors.
Some experts say they are especially concerned that coronavirus droplets could spread through air vents in offices, which are crowded because the city has not yet developed a robust culture of remote work.
People are removing masks for lunch or when they get back to their cubicle because they assume their cubicle is their private space, said Yeung King-lun, a professor of chemical and biological engineering at the Hong Kong University of Science and Technology.
But remember: The air youre breathing in is basically communal.

Differences And Similarities With The Lancet Study
A study published in the journal The Lancet in May revealed that when kept at room temperature, “No infectious virus could be detected from treated smooth surfaces on day 4 or day 7 .”
For the surfaces which aren’t smooth, the study said: “No infectious virus could be recovered from printing and tissue papers after a 3-hour incubation, whereas no infectious virus could be detected from treated wood and cloth on day 2”.
For the case of surgical masks, the study showed that “a detectable level of the infectious virus could still be present on the outer layer of a surgical mask on day 7 “.
This Lancet was conducted under the following conditions: a droplet of virus culture was poured on a surface and left at room temperature with a relative humidity of around 65 per cent.
Even as the two studies differ on the number days for which Covid-19 or SARS-CoV-2 virus remains infectious, both showed that Covid-19 or SARS-CoV-2 was more stable on smooth surfaces.
Can People Without Symptoms Spread The Virus To Others
“Without symptoms” can refer to two groups of people: those who eventually do have symptoms and those who never go on to have symptoms . During this pandemic, we have seen that people without symptoms can spread the coronavirus infection to others.
A person with COVID-19 may be contagious 48 hours before starting to experience symptoms. In fact, people without symptoms may be more likely to spread the illness, because they are unlikely to be isolating and may not adopt behaviors designed to prevent spread.
But what about people who never go on to develop symptoms? A study published in;JAMA Network Open;found that almost one out of every four infections may be transmitted by individuals with asymptomatic infections.
Getting vaccinated once you are eligible is important for protecting not just yourself but others as well; early evidence suggests that you’re less likely to infect others once you’ve been vaccinated.

Can You Get Covid
Coronaviruses need living host cells in order to thrive. Unlike bacteria or fungi, they cannot multiply in or on food.
Its still possible for the coronavirus to be present on food. Indeed, some research thats currently in pre-print has found that the virus can survive on refrigerated or frozen meats for weeks.
However, the notes that theres currently no evidence to support that the spread of COVID-19 is associated with food.
Additionally, taking appropriate food safety measures can help ensure that you dont get sick from food.
Lets explore some food safety tips that can help prevent you contracting the coronavirus as well as other harmful germs from the food you eat.
