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 from food?

It is highly unlikely that people can contract COVID-19 from food or food packaging. COVID-19 is a respiratory illness and the primary transmission route is through person-to- person contact and through direct contact with respiratory droplets generated when an infected person coughs or sneezes.There is no evidence to date of viruses that cause respiratory illnesses being transmitted via food or food packaging.

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.

Can I breastfeed my child if I am severely ill with coronavirus disease?

If you are severely ill with COVID-19 or suffer from other complications that prevent you from caring for your infant or continuing direct breastfeeding, express milk to safely provide breastmilk to your infant.If you are too unwell to breastfeed or express breastmilk, you should explore the possibility of relactation (restarting breastfeeding after a gap), wet nursing (another woman breastfeeding or caring for your child), or using donor human milk.

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.

Is headache a symptom of the coronavirus disease?

The virus can cause a range of symptoms, from ranging from mild illness to pneumonia. Symptoms of the disease are fever, cough, sore throat and headaches.

What is the recovery time for the coronavirus disease?

They found that for people with mild disease, recovery time is about two weeks, while people with severe or critical disease recover within three to six weeks.

Is the coronavirus disease more severe than the flu?

COVID-19 causes more severe disease than seasonal influenza.While many people globally have built up immunity to seasonal flu strains, COVID-19 is a new virus to which no one has immunity. That means more people are susceptible to infection, and some will suffer severe disease.Globally, about 3.4% of reported COVID-19 cases have died. By comparison, seasonal flu generally kills far fewer than 1% of those infected.

Are there medications to treat COVID-19?

See full answerNo pharmaceutical products have yet been shown to be safe and effective for the treatment of COVID-19. However, a number of medicines have been suggested as potential investigational therapies, many of which are now being or will soon be studied in clinical trials, including the SOLIDARITY trial co-sponsored by WHO and participating countries.In many countries, doctors are giving COVID-19 patients medicines that have not been approved for this disease. The use of licensed medicines for indications that have not been approved by a national medicines regulatory authority is considered “off-label” use.

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.

Can the coronavirus disease spread through sewage?

There is no evidence that the COVID-19 virus has been transmitted via sewerage systems with or without wastewater treatment.

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.

Can drinking alcohol help in preventing COVID-19?

Alcohol does not protect against COVID-19; access should be restricted during lockdown.

How do viruses get their name?

Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).

What is the coronavirus disease?

The coronavirus disease (COVID-19) is an infectious disease caused by a new strain of coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.

Does heat kill the coronavirus?

Heat at 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction).

Should coronavirus disease patients be isolated in hospitals?

WHO advises that all confirmed cases, even mild cases, should be isolated in health facilities, to prevent transmission and provide adequate care.But we recognize that many countries have already exceeded their capacity to care for mild cases in dedicated health facilities. In that situation, countries should prioritize older patients and those with underlying conditions.

Is smoking a risk-factors for COVID-19?

Smoking is already known to be a risk-factor for many other respiratory infections, including colds, influenza, pneumonia and tuberculosis. The effects of smoking on the respiratory system makes it more likely that smokers contract these diseases, which could be more severe. Smoking is also associated with increased development of acute respiratory distress syndrome, a key complication for severe cases of COVID-19, among people with severe respiratory infections.
