As a doctor, I will never forget December 2019, when the first cases of a mysterious virus have been reported in Wuhan, China. Initially, this was known as "serious respiratory coronavirus virus" - SARS-CO-V-2. Subsequently, the virus was officially named Coronavirus 2019, now shortened toCOVID-19 [Feminine. And what year it was!

As I write, theWorld Health Organizationhas confirmed more than 64 million cases around the world and 1.48 million deaths. We live through a global viral pandemic that has changed our lives in a way that we have never imagined. Incredible than a tiny virus-100 million Virus Covid-19 virus can integrate into a pinhead - has chosen these ravages and devastating.

Here are the latest information on what we know about Covid-19, its adult symptoms and what you can do to facilitate the symptoms if you contract it. Read on and ensure your health and health of others, do not miss theseWithout signs that you have already had coronavirus.

It takes pretty muchfive daysAfter being exposed to the virus so that symptoms appear. About97.5%People who develop symptoms do it within 11.5 days.

Over the last ten months, statistics have been collected on the type and frequency of VVID symptoms. At first, we were told to look for a dry cough and a fever, but more recent information suggests that other symptoms can be even more common. A recentEuropean studyFrom 1,420 patients admitted to 18 hospitals in Europe reported symptoms of COVID in the following frequency order:

• Headache 70.3%
• Loss of smell 70.2%
• Nasal obstruction 67.8%
• Cough 63.2%
• Weakness 63.3%
• Muscle pain 65.2%
• Nose COUNNY 61.1%
• Loss of appetite 54.2%
• Sore throat 52.9%
• Fever 45.4%

Interestingly, groups of symptoms differed depending on age and sex.

• The youngest patients more often had ear symptoms, nose and throat.
• Elderly patients more often had fever, loss of appetite and fatigue.
• The loss of smell, fatigue, headache and nasal obstruction were more common in women.

In another recent publication in theBmjThe authors studied 20,133 hospitalized patients with COVID-19. They found that the symptoms appeared to be clusters: a respiratory cluster (cough, shortness of breath, expression and fever), musculoskeletal cluster (joint pain, headache and fatigue) and a gastrointestinal cluster (abdominal pain, diarrhea and Vomiting.)

Many patients who are infected with COVID-19 do not have any symptoms. But how common is it? In April, theCebmtried to answer this question. They tabulated the results of various sources and concluded

• 5% - 80% of COVID patients are asymptomatic
• Some asymptomatic cases will develop symptoms
• Children and young adults often have no symptoms

NBC NewsReported on a study of 217 people on a cruise ship traveling from Australia to Antarctica. There, 59% have been positive for Covid-19, but only 19% had symptoms. A complete 81% were asymptomatic.

In another recent publication inJAMA internal medicineThe authors studied 303 patients admitted to the hospital with COVID-19 in Cheonan, South Korea. Of them, 110 were asymptomatic before starting themselves. However, the other 21 symptoms developed between days 13 and 20 days of isolation.

Note, the study showed that the asymptomatic group had the same amount of virus in their nose, throat and lungs as patients with symptoms. The authors commented that those with asymptomatic infection "do not seem different" of those with symptoms. They may be less effective for transmitting the virus as they do not touch or do not dissipate. However, the difference is that people with symptoms know they have the virus and stay at home. Those who are not aware, they continue to continue their normal daily activities and disseminate more viruses.

You can not say that is infected by Covid-19. Look around you; It could be anyone. The problem is that some people spread more viruses than others. The average person with COVID infects 1.3 to 3.5 other people. If you infect more people than that, you are called a "super-spreader. "

Super spreaders can

• Have a profession that gives them a high contact rate with other people, such as a merchant, a hairdresser or a waitress
• Travel frequently; They can often use public transport or global
• Participate in group events or mass gatherings, for example, singing in a choir or attend regular church services
• Do not comply with infection control measures; Studies show up to50%people continue as normal in a pandemic and do not attend the rules
• It suffices to spread more viruses, for reasons that are unclear, possibly genetic.

DataPrevious epidemics have shown that 20% of the population is responsible for 80% of infections.

Most people would not like to infect another person unconsciously. Any of us could be infected. It is imperative that we all act responsibly and that we follow the rules of infection control.

While the pandemic progresses, young adults are now considered as the most likely super-spreaders. Recently, the largest increase in infections in the UK has been in older adults20 to 29. Young adults may be wrongly believe that the virus is dangerous only for the elderly. It's far from the truth. In the United States, for example,1 out of 5Of the 4,226 patients 4,226 hospitalized patients for Covid-19 aged 20 to 44 years.

The authorities are afraid that the locking rules have been relaxed, young adults have become complacent. They must remember that the virus is not gone. All rules still need to be followed. Whenever we are wrong the guidelines, we risk infecting someone who can not fit well with infection. It may be or not, but it could be your parents, your grandparents and / or any other elderly or sick, neighbors and friends.

What does all this mean? This means that you can never say that could be infected with the virus. That's why stay safe, you need to keep at least six feet from other people who are not in your household, cover your nose and mouth with afacial mask, wash your hands regularly and carefully follow all the rules on social distancing.

When you feel sick and think it could be Covid, there are many other infections / conditions that could be. If your symptoms are light and improving, it is prudent to stay at home, rest and give your body time to combat infection.

However, if you are seriously ill or your symptoms aggravate, you must ask for help as soon as possible. The medical team will take your history, will examine and organize tests according to your symptoms and signs.

Here are some possible causes for your symptoms, other than Covid-19.

Viral infections

• FluAffects about 10% of the population each year.
• Syncytial Respiratory Virus (RSV)Most often affects babies and young children, where this can cause bronchiolitis. However, this also affects older people.
• Parainfluenza virusCauses commonly croups in babies and young children, but this also causes bronchitis and pneumonia in the elderly.
• Human metapneumovirusGenerally affects babies, young children, the elderly and those with an weakened immune system.
• Adenovirusis very common in the winter months and affects all age groups, causing a cold, rump, bronchitis and common pneumonia.
• Hantavirus pulmonary syndrome. Viruses propagated by rats and mice can cause symptoms similar to COVID-19. These infections are rare and occur in people who work in pest control.

Bacterial infections

• Streptococcus pneumoniaeCauses pneumonia during the winter months. This can affect babies, children and adults. You can receive protectionpneumococcal vaccination.
• Haemophilus influenzae. Babies are now vaccinated against this bacterium. The infection is much less common and can cause pneumonia and meningitis.
• Moxarella catarrhalis. A common cause of otitite medium (ear infection) in children, this bacterium can cause pneumonia in the elderly, especially in the underlying people.
• Atypical bacterial pneumonia. The most common are mycoplasm, chlamydia andLegionella pneumoniae.

Sepsisis a medical emergency threatening by life. Symptoms may imitate those of severe Covid-19 infection.

Non-infectious causes

• Heart failure. When the heart does not pump properly, the lungs can fill with fluid.
• Pulmonary embolfis a blood clot in the lung, which makes you feel suddenly badly and out of breath.
• Salicylate poisoningCan an overdose of aspirin cause acute pulmonary edema or accumulation of liquid in the lungs.

Diseases of the skin

Many different skin conditions have been reported with COVID, but they can be confused withVaricella Zoster,urticaria(urticaria),chilblainsWhereSyndrome of gloves and purepuric socks.

As the pandemic continues, various factors on infection become apparent.

The virus seems to be less deadly.

For example, in the United Kingdom,The University of OxfordCité a gross mortality rate of 18% in April, but only 1% in August.

This may be due to the fact that the virus continues, the highest infection rates are now observed in young adults (which are more likely to survive infection), and / or because hospitals improve to treat the infection.

The immune response to Covid-19 is still not well understood.

It takes pretty much10 daysfor the production of antibodies to go down. Those who have the most serious infections tend to have the strongest antibody response. It is still not clear why some people have a wrong answer in antibody - or, for those who have a good antibody response, how long the answer will be sustainable. Only time will say. There was a recently reported case in Hong Kong of a patient who became infected by Covid-19 for a second time.

There may be long-term complications.

For some coovidian patients, symptoms can be durable. TheBBCReports that 300,000 patients have symptoms of more than four weeks and 60,000 have presented symptoms for at least 3 months. This is called "Long Covid".

A wide range of symptoms can persist afterCOVID, from continuous breathlessness, fatigue, muscle fatigue and mental health conditions such as PTSD, anxiety and depression.
