Quick Answer: Under What Conditions Does COVID-19 Spread Easily?

What is a coronavirus?

Coronaviruses (CoV) are a large family of viruses transmitting between animals and people that cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV)..

How dangerous is the coronavirus disease?

Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.

Who is most at risk for COVID-19?

COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system.​

What are the factors that can determine transmission risk of COVID-19?

Factors that determine transmission risk include whether a virus is still replication-competent, whether the patient has symptoms, such as a cough, which can spread infectious droplets, and the behavior and environmental factors associated with the infected individual.

Can the coronavirus disease spread through feces?

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.

Can COVID-19 cause severe disease?

While COVID-19 is spreading rapidly, most people will experience only mild or moderate symptoms. That said, this coronavirus can cause severe disease in some people.

Is it normal to experience pandemic fatigue during the COVID-19 pandemic?

In recent weeks, many countries have been reporting an increase in “pandemic fatigue” – people are feeling demotivated about following recommended behaviours to protect themselves and others from the virus.Finding effective ways to tackle this fatigue and reinvigorate public vigilance is a growing challenge as the crisis continues. Pandemic fatigue evolves gradually over time and is affected by the cultural, social, structural and legislative environment.

How can the virus that causes COVID-19 spread through surfaces?

The virus can also spread after infected people sneeze, cough on, or touch surfaces, or objects, such as tables, doorknobs and handrails. Other people may become infected by touching these contaminated surfaces, then touching their eyes, noses or mouths without having cleaned their hands first.

How does COVID-19 mostly spread?

The virus spreads mainly through the air when people are near each other. It leaves an infected person as they breathe, cough, sneeze, or speak and enters another person via their mouth, nose, or eyes. It might also spread via contaminated surfaces.

What should I do if I feel unwell during the COVID-19 pandemic?

See full answer• Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches and pains, headache, sore throat, nasal congestion, red eyes, diarrhoea, or a skin rash.• Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever, until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.• If you have a fever, cough and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can and follow the directions of your local health authority.• Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities.

Should you meet with other people during the COVID-19 pandemic?

In this difficult period it is best to meet virtually but if you have to meet others, do it carefully and with the right precautions.

Are smokers more vulnerable to contracting COVID-19?

Tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

What are some of the symptoms of COVID-19?

Most people who are infected with the SARS-CoV-2 virus have respiratory symptoms. They start to feel a little bit unwell, they will have a fever, they may have a cough or a sore throat or sneeze. In some individuals, they may have gastrointestinal symptoms. Others may lose the sense of smell or the sense of taste.

How can one stay physically active during COVID-19 self-quarantine?

Walk. Even in small spaces, walking around or walking on the spot, can help you remain active. If you have a call, stand or walk around your home while you speak, instead of sitting down.

What are the dangers of smoking my waterpipe during the coronavirus disease pandemic?

The main ingredient used in waterpipe is tobacco, and its use has both acute and long-term harmful effects on the respiratory and cardiovascular systems [24] [25], likely increasing the risk of diseases including coronary artery disease and COPD [26].The communal nature of waterpipe smoking means that a single mouthpiece and hose are often shared between users, especially in social settings [27]. In addition, the waterpipe apparatus (including the hose and chamber) itself may provide an environment that promotes the survival of microorganisms outside the body.

Can COVID-19 spread in hot and humid climates?

See full answerFrom the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose. 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.

What are the mild symptoms of COVID-19?

The severity of COVID-19 varies. The disease may take a mild course with few or no symptoms, resembling other common upper respiratory diseases such as the common cold.

Can people with mild COVID-19 symptoms recover at home?

People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.

How long does the virus that causes COVID-19 last on surfaces?

Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.

What is the most likely ecological reservoirs for coronavirus disease?

The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.

Do COVID-19 and tuberculosis spread in the same way?

See full answerTB bacilli remain suspended in the air in droplet nuclei for several hours after a TB patient coughs, sneezes, shouts, or sings, and people who inhale them can get infected. The size of these droplet nuclei is a key factor determining their infectiousness. Their concentration decreases with ventilation and exposure to direct sunlight.COVID-19 transmission has primarily been attributed to the direct breathing of droplets expelled by someone with COVID-19 (people may be infectious before clinical features become apparent). Droplets produced by coughing, sneezing, exhaling and speaking may land on objects and surfaces, and contacts can get infected with COVID-19 by touching them and then touching their eyes, nose or mouth . Handwashing, in addition to respiratory precautions, are thus important in the control of COVID-19.
