冠状病毒疾病（Covid-19）：问题与解答
世界卫生组织继续监测和应对这一暴发。随着有关COVID-19，它如何传播以及如何影响世界各地的人们的更多知识，这些问题和答案将得到更新。
什么是冠状病毒？
冠状病毒是可能导致动物和人类疾病的广泛的病毒家族。众所周知，人类中许多冠状病毒会引起呼吸系统疾病，其严重程度从普通感冒到更严重的疾病，例如中东呼吸综合症（MERS）和严重急性呼吸综合症（SARS）。最近发现的冠状病毒可导致Covid-19疾病。
什么是Covid-19病？
Covid-19病是一种由冠状病毒株最后发现的病毒引起的传染病。在2019年12月在中国武汉市爆发爆发之前，尚不知道这种新病毒及其疾病的存在.Covid-19现已变成影响世界许多国家的大流行病。
Covid-19病的症状是什么？
COVID-19的最常见症状是发烧，疲劳和干咳。其他较不常见但某些患者可能会遇到的症状包括：疼痛和酸痛，鼻塞，头痛，结膜炎，喉咙痛，腹泻，味觉或嗅觉丧失以及出现皮疹或手指变色或脚趾。这些症状通常较轻，并逐渐开始。有些人只感染了非常轻微的症状。
大多数人（约80％）无需特殊治疗即可从疾病中康复。但是，大约每五名患有Covid-19疾病的人中就有一个症状恶化，而且他呼吸困难。老年人和患有其他健康问题（例如高血压，心脏病和肺病，糖尿病或癌症）的人中，发生严重并发症的风险增加。任何年龄的所有人，如果发烧和/或咳嗽并伴有呼吸困难/呼吸急促，胸部疼痛或压迫，语言或动作丧失，都应立即就医。建议尽可能提前联系医生或医疗保健机构，以便可以将患者定向到适当的诊所。
如果我有COVID-19症状怎么办？什么时候应该就医？
如果您的症状较轻，例如轻微咳嗽或轻微发烧，则通常无需就医。待在家里，隔离自己，并监视症状。并遵守有关自我隔离的国家准则。但是，如果您生活在疟疾或登革热很普遍的地区，则必须不要忽视发烧的症状。寻求医疗帮助。当您去医疗机构时，请尽可能戴上枪口，与他人之间保持至少一米的距离，并避免接触手周围的表面。如果患者是小孩，请帮助他遵守这些提示。
如果呼吸困难或胸痛/压迫，请立即就医。如果可能，请提前联系医生，以便他可以将您带往适当的医疗机构。
Covid-19疾病如何传播？
人们可以从其他感染该病毒的人那里感染COVID-19。该疾病主要通过小液滴在人与人之间传播，当患者咳嗽，打喷嚏或说话时，Covid-19病毒会从他们的鼻子或嘴中分泌出小液滴。这些液滴重量较重，因为它们不会移动到遥远的地方，而是会迅速掉落到地面上。如果人们从感染病毒的人身上吸入这些飞沫，他们就会感染Covid-19疾病。因此，与他人保持至少1米（3英尺）的距离非常重要。这些水滴可能会落在人周围的物体和表面上，例如桌子，门把手和楼梯栏杆。当人们触摸这些物体或表面，然后触摸其眼睛，鼻子或嘴巴时，它们可能会被感染。因此，重要的是经常用肥皂和水洗手，或者用酒精基的手部消毒剂进行清洁。
该组织正在评估有关传播COVID-19疾病的方法的正在进行的研究，并将继续发布其最新发现。
可以从没有疾病症状的人身上感染Covid-19感染吗？
Covid-19感染主要通过咳嗽或发烧或疲劳等其他症状的人分泌的呼吸道飞沫传播。但是许多Covid-19感染者仅表现出非常轻微的症状。在疾病的早期尤其如此。它实际上可以捕获轻度咳嗽且不感到不适的人的感染。
一些报告表明，即使没有症状的人也可以传播该病毒。尚不知道这种感染的程度。

Coronavirus Disease (Covid-19): Question and Answer
The World Health Organization continues to monitor and respond to this outbreak continuously. These questions and answers will be updated as more knowledge becomes available about COVID-19, how it spreads and how it affects people around the world.
What is Corona virus?
Coronaviruses are a broad family of viruses that may cause disease in animals and humans. It is known that a number of corona viruses in humans cause respiratory diseases ranging in severity from common cold to more severe diseases such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). The recently discovered Coronavirus causes Covid-19 disease.
What is Covid-19 disease?
Covid-19 disease is an infectious disease caused by the last discovered virus of the Coronavirus strain. There was no knowledge of the existence of this new virus and its disease before the outbreak began in the Chinese city of Wuhan in December 2019. Covid-19 has now turned into a pandemic affecting many countries of the world.
What are the symptoms of Covid-19 disease?
The most common symptoms of COVID-19 are fever, fatigue and a dry cough. Other symptoms that are less common but may be experienced by some patients include: pains and aches, nasal congestion, headache, conjunctivitis, sore throat, diarrhea, loss of sense of taste or smell, and the appearance of a rash or discoloration of the fingers or toes. These symptoms are usually mild and start gradually. Some people become infected with only very mild symptoms.
Most people (about 80%) recover from the disease without needing special treatment. However, symptoms worsen in approximately one out of every 5 people who have Covid-19 disease, and he suffers from difficulty breathing. The risk of developing severe complications increases among the elderly and people with other health problems such as high blood pressure, heart and lung disease, diabetes or cancer. All persons of any age should seek medical attention immediately if they develop a fever and / or cough accompanied by difficulty breathing / shortness of breath, pain or pressure in the chest, or loss of speech or movement. It is recommended, as much as possible, to contact a doctor or health care facility in advance, so that the patient can be directed to the appropriate clinic.
What do I do if I have COVID-19 symptoms and when should I seek medical attention?
If your symptoms are mild, such as a slight cough or a slight fever, then there is generally no need to seek medical attention. Stay home, isolate yourself, and monitor your symptoms. And follow national guidelines on self-isolation. But if you live in an area where malaria or dengue fever is common, it is imperative that you do not ignore the symptoms of a fever. Seek medical help. When you go to a health care facility, wear a muzzle if possible, keep a distance of at least one meter between yourself and others and avoid touching the surfaces around your hands. And if the patient is a child, help him adhere to these tips.
Seek medical attention right away if you have difficulty breathing or chest pain / pressure. Contact the doctor in advance, if possible, so that he can direct you to the appropriate health facility.
How does Covid-19 disease spread?
People can catch COVID-19 from other people who have the virus. The disease is spread mainly from person to person through small droplets that a person with Covid-19 secretes from their nose or mouth when they cough, sneeze or speak. These droplets are of relatively heavy weight, as they do not move to a distant place, but rather fall quickly to the ground. People can contract Covid-19 disease if they breathe in these droplets from a person who has the virus infection. Therefore it is important to keep a distance of at least 1 meter (3 feet) from others. These droplets may land on objects and surfaces surrounding a person, such as tables, doorknobs, and stair railings. People can then become infected when they touch these objects or surfaces and then touch their eyes, nose, or mouth. Therefore, it is important to wash hands frequently with soap and water, or to clean them with an alcohol-based hand rub disinfectant.
The organization is assessing ongoing research on ways to spread the COVID-19 disease and will continue to publish its latest findings.
Can Covid-19 infection be caught from a person without symptoms of the disease?
Covid-19 infection is spread mainly through respiratory droplets secreted by a person who is coughing or has other symptoms such as fever or fatigue. But many people with Covid-19 infection show only very mild symptoms. This is especially true in the early stages of the disease. And it can actually catch the infection from someone who has a mild cough and does not feel sick.
Some reports indicate that the virus can be transmitted even from people without symptoms. The extent of infection in this way is not known yet.
