We entered the fight against COVID-19, bringing updated recommendations, according to the scientific guidelines of the main health agencies in the world.

We developed a digital triage to contribute to the epidemiological mapping of COVID-19, based on symptoms and behaviors, and to allow us to draw conclusions about the ideal forms of social interaction during the control of this pandemic.

About COVID-19

SARS-CoV-2 is a virus that belongs to the coronavirus family and can cause COVID-19, a contagious viral infection that mainly attacks the throat and lungs.

It is a new disease not yet deeply known by the scientific community. It was first identified in December 2019 in the city of Wuhan, China.

Common signs of infection include symptoms such as fever, cough, sore throat, shortness of breath and difficulty breathing.

How does COVID-19 spread?

The new coronavirus is transmitted through the airways, especially when the infected person coughs or sneezes. Releasing droplets that contaminate other people, objects and surfaces, around the infected person.

A person can become infected mainly by involuntarily touching the hand to the face. Thus, allowing SARS-CoV-2 to have contact with your mouth, nose or eyes and so on into your body, which can trigger COVID-19 disease.

  • Contact with infected people

    The coronavirus, SARS-CoV-2, spreads between humans directly and indirectly. Its contamination can be caused by simple body contact, or when an infected person is very close to other uninfected people.

  • Being very close to people

    We naturally expel particles when we speak, cough or sneeze. Droplets of saliva from an infected with coronavirus, can stay in the air for a while and can be contracted by another person through the airways.

  • Touching the eyes, nose or mouth

    SARS-CoV-2 also stays on surfaces for a while, and it can contaminate a person who touches these places and then touch his mouth, nose or eyes, and thus viruses will enter your body.

What are the symptoms of COVID-19?

Symptoms are changes in the perception that each person has of their own body, their metabolism or their sensations. That is why you should make an assessment against your own perceptions of the previous days.

The general symptoms of COVID-19 are: fever, dry cough, shortness of breath, difficulty breathing, headache and body aches, conjunctivitis and decreased smell and taste. Pay attention to the main symptoms:

  • Persistent Fever

    One of the most common symptoms. In the first week the fever tends to be low, around 99.5 ºF (37.5 ºC) and may increase, from the second week, to more than 100.5 ºF (38 ºC).

  • Dry Cough

    COVID-19's cough is usually dry, initially without much secretion, and is a symptom that intensifies over the days. When combined with any of these others it is a warning sign.

  • Difficulty Breathing

    The most worrying symptom, even when perceived without any other symptom. Generating a feeling of tiredness and shortness of breath on exertion, which can evolve to shortness of breath at rest.

Stay at home and call your doctor: If you have flu-like symptoms, shortness of breath and no worsening of your general condition, stay at home and seek remote guidance. If you have more than one symptom of COVID-19 at the same time, call your doctor as soon as possible.

How to protect yourself?

There is currently no vaccine for the COVID-19 virus. The best way to prevent it is to avoid exposure to the virus and frequently do hand and face hygiene.

  • Often, every two hours, even at home, with soap and water for at least 20 seconds and especially after being in a public place, coughing or sneezing.
  • Avoid leaving home, but if you need to leave, always keep a minimum distance of 2 meters from other people. If you are going to exercise outdoors, keep more distance from others.
  • Police yourself to control the movements we involuntarily make by touching your hands to your face. SARS-CoV-2 contact should be avoided mainly in the eyes, mouth and nose.
  • Whenever you leave the house, use masks, and whenever you cough or sneeze, cover your mouth and nose with a tissue or the inside of your elbow. Then clean your arm or handkerchief.
  • Daily sanitize objects in your home such as tables, switches, door handles, bathrooms and taps. Personal effects should also be cleaned frequently, such as a cell phone.

Treatment for COVID-19

Although research is happening at high speed and in quantity around the world, there is still no scientifically recognized treatment protocol for the cure of COVID-19 disease.

Likewise, research for vaccine development is evolving, but it is still a non-existent solution.

Stay tuned for news about scientific developments in treatments and vaccines in the content within the Heart Care App. Do not self-medicate, always consult your doctor first.

Numbers from our mapping of COVID-19 in Brazil

We created a mapping of these data in a statistical way and segmented by the Brazilian states, according to the result of the individual triage of each participant of this self-test, presenting statistical data on the level of severity risk in case of being affected by the disease and the probability of the participants being infected with the new coronavirus.

Rate of people who are probably infected

In this map, we identify territorially, by federal state of Brazil, the proportion of people likely to be infected with the new coronavirus.

This group includes all people who were identified in this triage as having high and low probability of being infected, symptomatically or asymptomatically, and also those who have already had positive diagnoses of infection, in laboratory tests, and who are still not considered cured.

The other cases, which are not part of this percentage, are cured cases and those with a very low or remote probability of being infected.

Rate of people at risk of progressing to a severe case

In this map, we identified the proportion of people at risk of developing more severe cases of COVID-19, which represent a high probability of requiring hospitalization if they are infected with the new coronavirus.

The percentage indicated on the map identifies the proportion of people who were identified in this assessment of the risk of progressing to a severe case in the event of being affected by the disease, as being part of the high or medium-high risk groups, considering age, physiological and behavioral data, in addition to the coexistence of chronic diseases (comorbidities).

The other cases, which are not part of the presented percentage, are the participants classified as people with low, medium-low or medium risk, according to the criteria indicated.

Questions and answers about Covid-19

Currently, there are lots of dubious information about the disease which, together with fake news, creates uncertainty for the entire population. So, we move to draw up a guide with questions and answers in addition to essential prevention information already circulating widely.

We follow scientific, medical, epidemiological and social, guidelines from different health institutions, such as the Centers for Disease Control and Prevention (CDC), the United Nations (UN) and the World Health Organization (WHO), among others.

Our goal is to collaborate with the sharing of serious and relevant information so that the understanding of the coronavirus is broadened.

These questions and answers will be updated as more is learned about COVID-19, how to prevent it, how it spreads, with what intensity and how it is affecting people around the world.

As a health care company that relies on data science, Heart Care can greatly contribute to understanding and analyzing effective ways of controlling the progress of the pandemic.

Following are information and recommendations from WHO, addressing the most frequent questions and inquiries from people around the world. For more information, see the WHO coronavirus page regularly: https://www.who.int/emergencies/diseases/novel-coronavirus-2019

Coronaviruses are a large family of viruses which may cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus, SARS-CoV-2, causes the COVID-19 disease.
COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.
The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea.

These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell.

Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.
People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.

These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth.

Can the virus that causes COVID-19 be transmitted through the air?

Studies to date suggest that the virus that causes COVID-19 is mainly transmitted through contact with respiratory droplets rather than through the air.

Can COVID-19 be caught from a person who has no symptoms?

The main way the disease spreads is through respiratory droplets expelled by someone who is coughing. The risk of catching COVID-19 from someone with no symptoms at all is very low. However, many people with COVID-19 experience only mild symptoms.

This is particularly true at the early stages of the disease. It is therefore possible to catch COVID-19 from someone who has, for example, just a mild cough and does not feel ill.

Can I catch COVID-19 from the feces of someone with the disease?

The risk of catching COVID-19 from the feces of an infected person appears to be low. While initial investigations suggest the virus may be present in feces in some cases, spread through this route is not a main feature of the outbreak.

WHO is assessing ongoing research on the ways COVID-19 is spread and will continue to share new findings. Because this is a risk, however, it is another reason to clean hands regularly, after using the bathroom and before eating.
Protection measures for everyone:

Stay aware of the latest information on the COVID-19 outbreak, available on the WHO website and through your national and local public health authority. Many countries around the world have seen cases of COVID-19 and several have seen outbreaks.

Some countries have succeeded in slowing or stopping their outbreaks. However, the situation is unpredictable so check regularly for the latest news.

You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:

1) Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.

Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.

2) Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.

Why? When someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease.

3) Avoid touching eyes, nose and mouth.

Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and can make you sick.

4) Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately.

Why? Droplets spread virus. By following good respiratory hygiene you protect the people around you from viruses such as cold, flu and COVID-19.

5) Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority.

Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections.

6) Keep up to date on the latest COVID-19 hotspots (cities or local areas where COVID-19 is spreading widely). If possible, avoid traveling to these places – especially if you are an older person or have diabetes, heart or lung disease.

Why? You have a higher chance of catching COVID-19 in one of these areas.

Protection measures for persons who are in or have recently visited (past 14 days) areas where COVID-19 is spreading

1) Follow the guidance outlined above (Protection measures for everyone)

2) Self-isolate by staying at home if you begin to feel unwell, even with mild symptoms such as headache, low grade fever (37.3 C or above) and slight runny nose, until you recover. If it is essential for you to have someone bring you supplies or to go out, e.g. to buy food, then wear a mask to avoid infecting other people.

Why? Avoiding contact with others and visits to medical facilities will allow these facilities to operate more effectively and help protect you and others from possible COVID-19 and other viruses.

3) If you develop fever, cough and difficulty breathing, seek medical advice promptly as this may be due to a respiratory infection or other serious condition. Call in advance and tell your provider of any recent travel or contact with travelers.
The risk depends on where you are - and more specifically, whether there is a COVID-19 outbreak unfolding there.

For most people in most locations the risk of catching COVID-19 is still low. However, there are now places around the world (cities or areas) where the disease is spreading. For people living in, or visiting, these areas the risk of catching COVID-19 is higher.

Governments and health authorities are taking vigorous action every time a new case of COVID-19 is identified. Be sure to comply with any local restrictions on travel, movement or large gatherings. Cooperating with disease control efforts will reduce your risk of catching or spreading COVID-19.

COVID-19 outbreaks can be contained and transmission stopped, as has been shown in China and some other countries. Unfortunately, new outbreaks can emerge rapidly. It’s important to be aware of the situation where you are or intend to go. WHO publishes daily updates on the COVID-19 situation worldwide.

You can see these at
Illness due to COVID-19 infection is generally mild, especially for children and young adults. However, it can cause serious illness: about 1 in every 5 people who catch it need hospital care. It is therefore quite normal for people to worry about how the COVID-19 outbreak will affect them and their loved ones.

We can channel our concerns into actions to protect ourselves, our loved ones and our communities. First and foremost among these actions is regular and thorough hand-washing and good respiratory hygiene. Secondly, keep informed and follow the advice of the local health authorities including any restrictions put in place on travel, movement and gatherings.

While we are still learning about how COVID-2019 affects people, older persons and persons with pre-existing medical conditions (such as high blood pressure, heart disease, lung disease, cancer or diabetes) appear to develop serious illness more often than others.
No. Antibiotics do not work against viruses, they only work on bacterial infections. COVID-19 is caused by a virus, so antibiotics do not work. Antibiotics should not be used as a means of prevention or treatment of COVID-19. They should only be used as directed by a physician to treat a bacterial infection.
While some western, traditional or home remedies may provide comfort and alleviate symptoms of COVID-19, there is no evidence that current medicine can prevent or cure the disease.

Self-medication is not recommended in any situation and with any medicines, including antibiotics, as a prevention or cure for COVID-19.

However, there are several ongoing clinical trials that include both western and traditional medicines.
Not yet. To date, there is no vaccine and no specific antiviral medicine to prevent or treat COVID-2019. However, those affected should receive care to relieve symptoms.

People with serious illness should be hospitalized. Most patients recover thanks to supportive care.

Possible vaccines and some specific drug treatments are under investigation, and being tested through clinical trials. WHO is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19.

The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue, and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing. See Basic protective measures against the new coronavirus The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue, and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing. See Basic protective measures against the new coronavirus https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks.
No. The virus that causes COVID-19 and the one that caused the outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003 are related to each other genetically, but the diseases they cause are quite different.

SARS was more deadly but much less infectious than COVID-19. There have been no outbreaks of SARS anywhere in the world since 2003.
Only wear a mask if you are ill with COVID-19 symptoms (especially coughing) or looking after someone who may have COVID-19.

Disposable face mask can only be used once. If you are not ill or looking after someone who is ill then you are wasting a mask. There is a world-wide shortage of masks, so WHO urges people to use masks wisely.

WHO advises rational use of medical masks to avoid unnecessary wastage of precious resources and mis-use of masks. See Advice on the use of masks: https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks

1) Remember, a mask should only be used by health workers, care takers, and individuals with respiratory symptoms, such as fever and cough, unless if your local health authorities have determined other way.

2) Before touching the mask, clean hands with an alcohol-based hand rub or soap and water.

3) Take the mask and inspect it for tears or holes.

4) Orient which side is the top side (where the metal strip is).

5) Ensure the proper side of the mask faces outwards (the coloured side).

6) Place the mask to your face. Pinch the metal strip or stiff edge of the mask so it moulds to the shape of your nose.

7) Pull down the mask’s bottom so it covers your mouth and your chin.

After use, take off the mask; remove the elastic loops from behind the ears while keeping the mask away from your face and clothes, to avoid touching potentially contaminated surfaces of the mask.

Discard the mask in a closed bin immediately after use.

Perform hand hygiene after touching or discarding the mask – Use alcohol-based hand rub or, if visibly soiled, wash your hands with soap and water.
The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease.

Most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days. These estimates will be updated as more data become available.
Coronaviruses are a large family of viruses that are common in animals. Occasionally, people get infected with these viruses which may then spread to other people. For example, SARS-CoV was associated with civet cats and MERS-CoV is transmitted by dromedary camels. Possible animal sources of COVID-19 have not yet been confirmed.

To protect yourself, such as when visiting live animal markets, avoid direct contact with animals and surfaces in contact with animals. Ensure good food safety practices at all times.

Handle with care raw meat, milk or animal organs to avoid contamination of uncooked foods and avoid consuming raw or undercooked animal products.
1) We are aware of instances of animals and pets of COVID-19 patients being infected with the disease;

2) As the intergovernmental body responsible for improving animal health worldwide, the World Organisation for Animal Health (OIE) has been developing technical guidance on specialised topics related to animal health, dedicated to veterinary services and technical experts (including on testing and quarantine);

3) There is a possibility for some animals to become infected through close contact with infected humans. Further evidence is needed to understand if animals and pets can spread the disease;

4) Based on current evidence, human to human transmission remains the main driver;

5) It is still too early to say whether cats could be the intermediate host in the transmission of the COVID-19.
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses.

Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
Yes. The likelihood of an infected person contaminating commercial goods is low and the risk of catching the virus that causes COVID-19 from a package that has been moved, travelled, and exposed to different conditions and temperature is also low.
The following measures ARE NOT effective against COVID-2019 and can be harmful:

1) Smoking

2) Wearing multiple masks

3) Taking antibiotics (See question above: Are there any medicines of therapies that can prevent or cure COVID-19?)

In any case, if you have fever, cough and difficulty breathing seek medical care early to reduce the risk of developing a more severe infection and be sure to share your recent travel history with your health care provider.
Currently, the source of SARS-CoV-2, the coronavirus (CoV) causing COVID-19 is unknown.

All available evidence suggests that SARS-CoV-2 has a natural animal origin and is not a constructed virus. SARS-CoV-2 virus most probably has its ecological reservoir in bats.

SARS-CoV-2, belongs to a group of genetically related viruses, which also include SARS-CoV and a number of other CoVs isolated from bats populations. MERS-CoV also belongs to this group, but is less closely related.
The first human cases of COVID-19 were identified in Wuhan City, China in December 2019. At this stage, it is not possible to determine precisely how humans in China were initially infected with SARS-CoV-2.

However, SARS-CoV, the virus which caused the SARS outbreak in 2003, jumped from an animal reservoir (civet cats, a farmed wild animal) to humans and then spread between humans.

In a similar way, it is thought that SARS-CoV-2 jumped the species barrier and initially infected humans, but more likely through an intermediate host, that is another animal species more likely to be handled by humans - this could be a domestic animal, a wild animal, or a domesticated wild animal and, as of yet, has not been identified.

Until the source of this virus is identified and controlled, there is a risk of reintroduction of the virus in the human population and the risk of new outbreaks like the ones we are currently experiencing.
The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or speaks. These droplets are too heavy to hang in the air. They quickly fall on floors or surfaces.

You can be infected by breathing in the virus if you are within 1 meter of a person who has COVID-19, or by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.
