COVID-19 is a new strain of coronaviruses that can transfer from animals
to humans. The virus causes respiratory disease, and it is called
"SARS-COV-2" and the disease it causes called " Coronavirus
disease 2019" (Abbreviated COVID-19).
Last Reviewed: April 2026 | Sources: DrJobPro Hiring Data Q1 2026.
There is a large family of coronaviruses that are common in many
different species of animals, including bats, cats, camels, and cattle. Coronaviruses
are named for the crown-like spikes on their surface. There are four
main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta.
WHO has declared COVID-19 as a global
pandemic on 12th March 2020. Coronavirus's first case was detected on 13th
December 2019, and the COVID-19 epicenter was in Wuhan, Hubei
province, China.
In the past, there were other types of human coronaviruses:
What is the difference between COVID-19 and influenza?
Middle East Respiratory Syndrome (MERS) and COVID-19 are different types
of diseases caused by viruses belong to a large family of Coronavirus. They are
different in the diseases they cause, but they are related to each other
genetically.
Symptoms
People affected by COVID-19 have a wide range of symptoms ranging from mild
symptoms to severe illness.
In some cases, the disease may lead to death. These include older
people and individuals with a weak immune system (underlying chronic
health conditions such as Diabetes, lung ailments, and cancer).
Symptoms may appear 2-14 days after exposure to the virus.
The most common symptoms are:
Note: Not all symptoms can
be seen in a person suspected to be infected by COVID-19.
Not everyone with cold or upper respiratory symptoms needs to be tested
for COVID-19.
Most people (about 80%) recover from the disease without needing special
treatment.
Emergency warning signs are:
If you notice any symptoms mentioned above, visit the nearest medical
Centre or hospital for further guidance and medical care.
Severe illness symptoms can lead to acute respiratory distress syndrome
(ARDS) and can lead to death.
Symptoms may appear 2-14 days after exposure to the virus. Yet,
in some cases, such as younger people, symptoms may be as delayed as 27-28
days.
Yes, in some cases, such as younger people, symptoms may be as
delayed as 27-28 days.
In some cases, the disease may lead to death. These include older
adults and individuals with a weak immune system (underlying chronic
health conditions such as Diabetes, lung ailments, and cancer).
Spread
Person to person spread: Through
respiratory droplets produced when an infected person coughs or sneezes or
through contaminated hands.
Between people who are in close contact with one another (within about 6
feet).
A person can also catch COVID-19 if he breathes in droplets from a
person with COVID-19 who coughs out or exhales droplets.
Contaminated Surfaces or objects: The
person can get COVID-19 by touching the surface that has the virus on it and
then touching their mouth or nose.
Because it spreads mainly from person to person contact, so if an
infected person coughs or sneezes, the other person can easily be infected
through the droplets that spread in the place.
These droplets are heavy, and they fall quickly to the surface/ground
below. If the person touches a surface with the virus on it, then he touches
his mouth or nose, he can get easily infected.
Infected people are thought to be most contagious when they have the
symptoms. However, in some cases, some people may spread the disease before
showing any symptoms, but this is not the main way to spread the virus.
The close contact has been defined as:
Regarding COVID-19, there are no certain studies to confirm how long
does COVID-19 stays on surfaces, but studies suggest that other coronaviruses
persist on surfaces for a few hours or up to several days. It depends on
several factors, including humidity, temperature, and surface type.
Suggest the colleague visit the nearest health center to get tested for
COVID-19 and to observe self-isolation.
If you are in close contact with the infected person, observe home
quarantine, and mentor your symptoms. Seek medical help if your symptoms
developed.
There is currently no evidence of human food packaging being associated
with the transmission of the Coronavirus that causes COVID-19. Like other
viruses, it is possible that Coronavirus can survive on surfaces or objects.
So, following food safety steps, clean, separate, and cook, is critical.
Prevention and protection
According to public health officials, social distancing, "physical
distancing," is increasing the physical space between people to avoid spreading
illness. This includes many different measures, including staying home, keeping
6 feet away, avoid closing public places, canceling events and large
gatherings, and restricting people's visits to your home.
Prevention is better than cure.
So you have to prevent the illness by doing the following:
Both washing hands with soap and using hand sanitizers are highly
effective ways of fighting the Coronavirus. Wash your hands with soap and water
for at least 20 seconds. If soap and water are not available, use alcohol-based
hand sanitizer with at least 60% alcohol, covering all your hands and rubbing
them together until they get dry.
Isolation and quarantine are ways used to protect the public by
preventing exposure to people who have or may have a contagious disease.
Isolation: separates sick
people with a contagious disease from people who are not sick.
Quarantine: separates and
restricts the movement of people who were exposed to a contagious disease to
see if they become sick.
The duration of home quarantine is for 14 days from contact with a
confirmed case. However, this period may vary from case to case depending on
the health of the person. It may continue until the risk of secondary
transmission to others become low.
Yes, if a suspect case turns out negative on laboratory testing, home
quarantine can end up early.
The home quarantine can be up to 28 days in some high-risk cases,
including:
Contact your doctor or the nearest
hospital or medical Centre immediately because you may need further care and
management.
Contact your doctor or the nearest
hospital or medical Centre immediately for further care and management.
Patients with severe illness symptoms of breathlessness, persistent
chest pain, bluish lips or face, abnormal pulse or blood pressure readings or
people with chronic diseases will need hospital care, and they can't be
quarantined at home.
Yes, as per new guidelines issued by the government of the UAE, the
general public has to wear face masks and gloves while stepping out of the
house for any reason, or you will get fined.
A medical face mask is effective for 8 hours. After that time, you have
to change it.
If it gets wet in between, it has to be changed immediately.
Avoid being exposed to this virus is the best way to prevent illness.
Thus, Self-isolation is a useful precautionary measure to help others around
you from contracting COVID-19. Try to avoid close contact with others as much
as possible.
COVID-19 and flu have common symptoms that can progress and become
life-threatening in both cases.
Doctors suspect Coronavirus if:
Investigations
Yes, there is a laboratory test for
COVID-19.
This is the test designed to detect the novel Coronavirus in respiratory
specimens, such as nasal or oral swabs.
It means that you have infected with Coronavirus, so you will be placed
in isolation to prevent spreading the virus to others.
It means that Coronavirus was not found in your sample. While the negative
test means you don't have Coronavirus, your doctor will consider the test
result together with all other aspects of your medical history, in case the
test result may be a false negative.
It is possible to have a false negative result in some people with
COVID-19 infection in the early stages before the symptoms appear, meaning you
might have an infection with Coronavirus even though the test is positive.
If COVID-19 is still suspected in your case, your health care provider
will consider pre-testing.
Treatment
As there is no specific treatment for the virus to date, the treatment
of COVID-19 depends on enhancing the immunity level of patients, treating the
symptoms, and easing complications.
Till now, there is no vaccine available to prevent COVID-19.
COVID-19 and influenza are entirely two
different viruses, and the seasonal influenza vaccine will not protect you
against COVID-19.
No, Antibiotics don't work against viruses; they only work on bacterial
infections. A virus, not bacteria, cause COVID-19.
Until this time, there are no authorized natural health products to
treat or protect COVID-19.
Relapse
However, there is no crucial answer to this question, and most people
may develop at least short immunity to the specific Coronavirus that causes
COVID-19.
Animals Related
While there is current research that links COVID-19 to certain types of
bats, there is no evidence that pets like cats or dogs pose a risk of infection
to humans. As a precautionary measure, avoid direct contact with animals or
surfaces in contact with animals. Also, avoid handling raw meat, milk, or
animal products with care to prevent contamination of uncooked food and avoid
uncooked products that come from animals.
There is no evidence that pets like cats
or dogs pose a risk of infection to humans. As a precautionary measure, avoid
direct contact with animals or surfaces in contact with animals and wash your
hands after handling animals or animal waste.
Yes, it is still recommended that people with COVID-19 limit contact
with animals until more information is known about the virus. If it is a must
to care for the pets by yourself, wear a mask and wash your hand before and
after handling the animals. Avoid petting, being kissed or licked, snuggling,
and sharing food.
There is no evidence; currently, that Coronavirus spread through poultry
products. Yet, you have to follow the food safety procedures and avoid uncooked
meat.
There is no evidence that non-vegetarian food should be avoided, but you
have to follow the food safety procedures: Separate, clean, and cook.
Children Related
Depending on available studies as of today, children don't appear to be
at higher risk for COVID-19 than adults. Most cases are for adults compared to
infants.
As per new guidelines issued by the UAE government, everyone should wear
masks while stepping out of the house for any purpose to prevent the spread of
COVID-19 and maintain public health.
No, Symptoms for children and adults are
the same. The most prominent symptoms for children are cold-like symptoms,
including fever, runny nose, and cough. Generally, children with confirmed
COVID-19 have presented with mild symptoms.
As per the advisory issued by the government of UAE and the Ministry of
Education, closure of all educational establishments (Schools, Universities) shall
be in force until further notice. The latest updates can be found on https://www.moe.gov.ae/En/Pages/Home.aspx.
To protect students, several procedures have been followed:
As per the current guidelines, cleaning, and daily disinfecting surfaces
with 1% Sodium Hypochlorite Solution offers protection from Novel Coronavirus.
The best way to avoid being infected is to avoid touching the
contaminated surfaces and washing hands with water and soap frequently.
Pregnancy-Related
It is always important for pregnant women to keep themselves protected
from illnesses. There is no evidence until now that pregnant women have a higher
chance of getting infected with COVID-19 than ordinary people.
There is still no evidence if a pregnant
woman with COVID-19 can pass the virus to her baby during pregnancy or
delivery. To date, the virus has not been found in samples of amniotic fluid or
breastmilk.
There have been a small number of reported problems with pregnancy or
delivery (e.g., preterm birth) in babies born to mothers who have COVID-19.
However, there is no evidence till now that any problems posed to infants of
pregnant women who have COVID-19.
There is no evidence until now that pregnant women have a higher chance
of getting infected with COVID-19 than ordinary people. Generally, they have to
protect themselves by practicing social distancing.
Elderly Related
In the elderly, the disease represents a severe form of illness that
leads to death. This is likely resulting from the presence of other diseases, a
weaker immune system, or worse overall health, including suffering from
Diabetes, Cancer, etc.
However, the most prominent symptoms for children are cold-like
symptoms, including fever, runny nose, and cough. Generally, children with
confirmed COVID-19 have presented with mild symptoms.
Follow protective measure:
Special Conditions (Asthma)
As per new guidelines issued by the UAE
government, everyone should wear masks while stepping out of the house for any
purpose to prevent the spread of COVID-19 and maintain public health.
In addition to wearing the mask, do the
following:
Special Conditions (Heart)
Results to date suggest that people with a heart-related problem appear
to have a higher risk of getting infected when exposed to viruses due to their
weak immune system and long-term medical condition.
Funerals
There is currently no confirmed risk of being in the same room with a
person who died of COVID-19. However, People should avoid touching the body of
the deceased without personal protective equipment.
Kissing, hugging, bathing, etc. of the dead body is not allowed. The
personal handling of the body of the deceased person should follow standard
precautions of wearing personal protective equipment.
As per the directives issued by WHO, the bathing of the body of the deceased
affected by COVID-19 is not allowed.
The body of the deceased has to be adequately packed in a body bag and
should be disposed of under controlled conditions.
Travel
"Don't travel" is highly recommended under the current
conditions. You can check with the appointed authorities for more information.
Avoid all non-essential commuting. The best way to avoid the virus is to
practice social-distancing or self-quarantine.
"Don't travel" is highly
recommended under the current conditions to curb the spread of COVID-19 and
reduce opportunities for virus transmission.
General Questions
As per the official website of WHO, there
are 264K deaths.
It is safe to visit the hospitals if you
have an acute care need. Follow updated guidelines for visitors and caregivers
set by the local health authorities.
If you touch your face with contaminated gloves, you may get infected.
The best practice is to wash your hands with water and soap frequently.
No, don't use disinfectant sprays or wipes to be used on your skin
because they may cause skin irritation. They are intended for use on hard,
non-porous surfaces.
Monitor yourself for symptoms and contact your doctor if you feel sick.
Yes. The likelihood of an infected person contaminating commercial goods
is low, and the risk of catching COVID-19 from a package that has been moved,
traveled, and exposed to different conditions is also low.
Some viruses, like the cold and flu, spread more when the weather is colder.
At this time, there is no evidence that the spread of COVID-19 will decrease
when the weather becomes warm.
At this time, there is no evidence that the new Corona Virus can be
transmitted from a mosquito bite.
No, hand dryers are not effective in killing the new Coronavirus.
UV lamps shouldn't be used to sterilize hands, or other areas of the
skin as UV radiation can cause skin irritation.
They are useful in detecting people who developed a fever because of the
infection of the Coronavirus.
However, they can't detect people who are not infected but are not yet
sick with a fever. This is because it takes between 2 and 14 days before people
who are affected become sick and develop a fever.
Eating garlic is healthy because it has some antimicrobial properties,
but no evidence eating garlic has prevented people from getting infected by a coronavirus.
No. Most people have mild symptoms and recover from the disease in 2
weeks with supportive medical care.
Phone cleaning tips:
If you touch the cough droplet of an infected person and then touch your
mouth, nose, or eyes, you may get sick.
The best way to avoid being exposed to this virus is to maintain social
distancing and limit visitors to come to your house.
It is useful, especially in public places, to practice routine cleaning
of high touch surfaces (counters, tabletops, doorknobs, keyboards, tablets)
daily with 1% Sodium Hypochlorite Solution.
