The speedy unfold of COVID-19 has sparked alarm worldwide. The World Well being Group (WHO) has declared a worldwide well being emergency, and lots of international locations are grappling with an increase in confirmed circumstances. Within the US, the Facilities for Illness Management and Prevention (CDC) is advising individuals to be ready for disruptions to each day life that will probably be essential if the virus spreads inside communities.

Under, we’re responding to a lot of questions on COVID-19 raised by Harvard Well being Weblog readers. We hope so as to add additional questions and replace solutions as dependable info turns into out there.

Does the virus unfold person-to-person?

What’s the incubation interval for the virus?

What are the signs?

Can people who find themselves asymptomatic unfold the virus?

Can the virus stay on material, carpet, and different tender surfaces? What about laborious surfaces?

Ought to I put on a face masks? Ought to my kids?

Ought to somebody who’s immunocompromised put on a face masks?

Ought to I settle for packages from China?

an I catch the virus by consuming meals ready by others?

Ought to I journey on a aircraft with my kids?

Is there a vaccine out there?

Is there a therapy out there?

How is that this virus confirmed?

How lethal is COVID-19?

What ought to individuals do in the event that they suppose they’ve the virus or their youngster does? Go to an pressing care clinic? Go to the ER?

Can individuals who recuperate from the virus nonetheless be carriers and due to this fact unfold it?

Does the virus unfold person-to-person?

Sure, the virus can unfold from one particular person to a different, almost definitely via droplets of saliva or mucus carried within the air for as much as six toes or so when an contaminated particular person coughs or sneezes, or via viral particles transferred when shaking arms or sharing a drink with somebody who has the virus.

Usually it’s apparent if an individual is sick, however there have been some circumstances the place individuals who didn’t but really feel sick had the virus and will unfold it.

Fundamental steps for avoiding flu and different infections — together with steps for handwashing proven on this video — are probably to assist cease the unfold of this virus. The CDC has a useful listing of preventive steps.

Quarantines and journey restrictions now in place in lots of counties, together with the US, are additionally meant to assist break the chain of transmission. Public well being authorities just like the CDC could suggest different approaches for individuals who could have been uncovered to the virus, together with isolation at residence and symptom monitoring for a time frame (normally 14 days), relying on degree of threat for publicity. The CDC has pointers for individuals who have the virus to assist with restoration and stop others from getting sick.

What’s the incubation interval for the virus?

An incubation interval is the time between catching an sickness and displaying signs of the sickness. Present estimates counsel that signs of COVID-19 normally seem inside round 5 days or much less typically, however the vary may very well be between one and 14 days.

What are the signs?

Fever, dry cough, hassle respiration, and typically pneumonia are the frequent signs of COVID-19. There have been some stories of gastrointestinal signs (nausea, vomiting, or diarrhea) earlier than respiratory signs happen, however that is largely a respiratory virus.

Those that have the virus could haven’t any apparent signs (be asymptomatic) or signs starting from gentle to extreme. In some circumstances, the virus is life-threatening or deadly.

Presently, it appears that evidently most individuals who get sick will recuperate from COVID-19. Restoration time varies and, for people who find themselves not severely sick, could also be just like the aftermath of a flulike sickness. Individuals with gentle signs could recuperate inside a number of days. Individuals who have pneumonia could take longer to recuperate (days to weeks). In circumstances of extreme, life-threatening sickness, it might take months for an individual to recuperate, or the particular person could die.

Can people who find themselves asymptomatic unfold the virus?

An individual who’s asymptomatic could also be shedding the virus and will make others sick. How usually asymptomatic transmission is happening is unclear.

Can the virus stay on material, carpet, and different tender surfaces? What about laborious surfaces?

Presently, there’s no proof that the virus could be transmitted from tender surfaces like material or carpet to people.

It’s doable that the virus may very well be on frequently-touched surfaces, similar to a doorknob, though early info suggests viral particles can be prone to survive for just some hours, in line with the WHO. This additionally assumes that somebody who’s sick with the virus has touched a floor after sneezing or coughing into their hand or rubbing their eye. That’s why private preventive steps like regularly washing arms with cleaning soap and water or an alcohol-based hand sanitizer, and wiping down often-touched surfaces with disinfectants or a family cleansing spray, are a good suggestion.

Ought to I put on a face masks? Ought to my kids?

Comply with public well being suggestions the place you reside. Presently, face masks usually are not really useful for most people within the US. Your threat of catching the virus within the US is prone to be low, since there’s little proof of neighborhood transmission right now. At this writing, just one confirmed case within the US is unrelated to journey to China or shut contact with vacationers from China.  Regardless that there are some confirmed circumstances of COVID-19 within the US, you’re more likely to catch and unfold influenza (the flu). (Thus far this season, there have been practically 30 million circumstances of flu and 17,000 deaths.)

Some well being services require individuals to put on a masks underneath sure circumstances, similar to if they’ve traveled from town of Wuhan, China or surrounding Hubei Province, or have been in touch with individuals who did or with individuals who have confirmed coronavirus.

If in case you have respiratory signs like coughing or sneezing, consultants suggest sporting a masks to guard others. This may increasingly assist include droplets containing any kind of virus, together with the flu, and shield shut contacts (anybody inside three to 6 toes of the contaminated particular person).

The CDC gives extra details about masks. The WHO gives movies and illustrations on when and find out how to use a masks.

Ought to somebody who’s immunocompromised put on a masks?

In case you are immunocompromised due to an sickness or therapy, discuss to your physician about whether or not sporting a masks is useful for you in some conditions. We’re at present in the course of a flu epidemic within the US. Against this, we now have restricted circumstances of COVID-19 and no proof of sustained person-to-person transmission in our communities. Right now, it wouldn’t make sense for somebody who’s immunocompromised to put on a masks when in public to lower threat for catching COVID-19. Nevertheless, in case your healthcare supplier advises you to put on a masks when in public areas as a result of you will have a very susceptible immune system, comply with that recommendation. But when masking has not been really useful to you to guard in opposition to the flu and quite a few different respiratory viruses, then it doesn’t make sense to me to advise sporting a masks to guard in opposition to COVID-19 right now.

Ought to I settle for packages from China?

There isn’t a purpose to suspect that packages from China harbor COVID-19. Keep in mind, this can be a respiratory virus just like the flu. We don’t cease receiving packages from China throughout their flu season. We must always comply with that very same logic for this novel pathogen.

Can I catch the virus by consuming meals ready by others?

We’re nonetheless studying about transmission of COVID-19. It’s not clear if that is doable, but when so it could be extra prone to be the exception than the rule. That stated, COVID-19 and different coronaviruses have been detected within the stool of sure sufferers, so we at present can’t rule out the potential for occasional transmission from contaminated meals handlers. The virus would probably be killed by cooking the meals.

Ought to I journey on a aircraft with my kids?

Preserve abreast of journey advisories from regulatory businesses and perceive that this can be a quickly altering state of affairs. At this writing, most journey all through the world is unrestricted (exceptions embody China and now South Korea). I just lately flew with my son and his buddy and didn’t convey any kind of masks.

In fact, if anybody has a fever and respiratory signs, that particular person ought to not fly if in any respect doable, however anybody who has a fever and respiratory signs and flies anyway ought to put on a masks on an airplane.

Is there a vaccine out there?

No vaccine is out there, though scientists are engaged on vaccines. In 2003, scientists tried to develop a vaccine to stop SARS however the epidemic ended earlier than the vaccine may enter scientific trials.

Is there a therapy out there?

Presently there is no such thing as a particular antiviral therapy for COVID-19. Therapy is due to this fact supportive, which implies giving fluids, medication to scale back fever, and, in extreme circumstances, supplemental oxygen. Individuals who turn out to be critically sick from COVID-19 may have a respirator to assist them breathe. Bacterial an infection can complicate this viral an infection. Sufferers could require antibiotics in circumstances of bacterial pneumonia in addition to COVID-19.

Antiviral remedies used for HIV and different compounds are being investigated.

There’s no proof that dietary supplements, similar to vitamin C, or probiotics will assist velocity restoration.

How is that this virus confirmed?

A specialised check should be finished to substantiate that an individual has COVID-19. Most testing within the US has been carried out on the CDC. Nevertheless, the purpose is to ship check kits to state laboratories so testing could be carried out domestically.

How lethal is COVID-19?

We don’t but know. Nevertheless, indicators counsel that many individuals could have had gentle circumstances of the virus and recovered with out particular therapy.

Very early on this epidemic, it seemed like about 20% of circumstances had been extreme. Individuals developed acute respiratory misery syndrome (ARDS), which causes tiny air sacs within the lungs to fill with fluid, crowding out air in order that not sufficient oxygen can attain the bloodstream.

As of February 25, 2020, the reported confirmed circumstances and deaths in China counsel the mortality fee is roughly 3%. It is very important do not forget that early on in an epidemic there’s a “tip of the iceberg” phenomenon the place we overestimate extra extreme circumstances and gentle or asymptomatic circumstances go unrecognized, so the mortality appears greater than the truth. That could be occurring once we converse of as much as 3% mortality. Against this, SARS had a mortality fee of round 10%; the MERS mortality fee is nearer to 30% to 40%. There seem like many extra COVID-19 circumstances confirmed than there have been with SARS and MERS.

What ought to individuals do in the event that they suppose they’ve the virus or their youngster does? Go to an pressing care clinic? Go to the ER?

If in case you have a well being care supplier or pediatrician, name them first for recommendation. If you happen to stay within the US, it’s way more prone to be the flu or one other viral sickness.

If you happen to would not have a physician and you might be involved that you just or your youngster could have COVID-19, contact your native board of well being. They’ll direct you to the perfect place for analysis and therapy in your space.

Solely individuals with signs of extreme respiratory sickness ought to search medical care within the ER. Extreme signs are speedy coronary heart fee, low blood stress, excessive or very low temperatures, confusion, hassle respiration, extreme dehydration. Name forward to inform the ER that you’re coming to allow them to be ready to your arrival.

Can individuals who recuperate from the virus nonetheless be carriers and due to this fact unfold it?

Individuals who get COVID-19 have to work with suppliers and public well being authorities to find out when they’re not contagious.
