Why Do Viruses Make Us Sick?

Is COVID-19 caused by a virus or by bacteria?

FACT: The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria.The virus that causes COVID-19 is in a family of viruses called Coronaviridae.

Antibiotics do not work against viruses.

Some people who become ill with COVID-19 can also develop a bacterial infection as a complication.

In this case, antibiotics may be recommended by a health care provider.

There is currently no licensed medication to cure COVID-19.

If you have symptoms, call your health care provider or COVID-19 hotline for assistance..

Can the coronavirus disease be transmitted in hot or humid climates?

From 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.

How long have coronaviruses existed?

The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.

What is the virus called which causes the coronavirus disease?

COVID-19 is caused by the virus SARS-CoV-2.

Can the coronavirus spread via feces?

There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.

Who is at risk for coronavirus?

See full answerThe virus that causes COVID-19 infects people of all ages. However, evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people (that is people over 60 years old); and those with underlying medical conditions (such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer). The risk of severe disease gradually increases with age starting from around 40 years. It’s important that adults in this age range protect themselves and in turn protect others that may be more vulnerable.WHO has issued advice for these two groups and for community support to ensure that they are protected from COVID-19 without being isolated, stigmatized, left in a position of increased vulnerability or unable to access basic provisions and social care.

Does COVID-19 survive in sewage?

While there is no evidence to date about survival of the COVID-19 virus in water or sewage, the virus is likely to become inactivated significantly faster than non-enveloped human enteric viruses with known waterborne transmission (such as adenoviruses, norovirus, rotavirus and hepatitis A).

What are coronaviruses?

Coronaviruses are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. 2019-nCoV is a new strain that has not been previously identified in humans and causes COVID19/coronavirus disease.

Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?

See full answerAt the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, 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.

Does consuming alcohol kill the COVID-19 virus?

Consuming alcohol will not destroy the virus, and its consumption is likely to increase the health risks if a person becomes infected with the virus. Alcohol (at a concentration of at least 60% by volume) works as a disinfectant on your skin, but it has no such effect within your system when ingested.

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.

Can the coronaviruses be transmitted between animals and people?

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

Does heat prevent COVID-19?

FACT: Exposing yourself to the sun or temperatures higher than 25°C DOES NOT protect you from COVID-19. You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19.

Can the coronavirus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

Can I get the coronavirus disease from swimming in a swimming pool?

Swimming in a well-maintained, properly chlorinated pool is safe. However, it is advisable to stay away from al crowded areas including crowded swimming pools. Keep 1 metre distance from people who sneeze or cough even in a swimming area.

What is the risk of dying for the older people?

Over 95% of these deaths occurred in those older than 60 years. More than 50% of all fatalities involved people aged 80 years or older. Reports show that 8 out of 10 deaths are occurring in individuals with at least one comorbidity, in particular those with cardiovascular disease, hypertension and diabetes, but also with a range of other chronic underlying conditions.

Is coronavirus a disease?

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
